Biological processes are driven by molecules that interact through specific molecular contacts, often to form a stable complex. These interactions are typically defined by the principles of thermodynamics as well as biomolecular structure and recognition. At the simplest level is the interaction between a target molecule with a specific binding site and a probing molecule that binds to that site, resulting in the bound complex.

The most straightforward solution would be to determine sequences of the dominating antibody forms in a polyclonal mixture to enable recombinant antibody generation and ensure reproducibility. This was recently made possible by the development of polyclonal antibody sequencing technology, which will be reviewed in this article.
The origin of hydrogen-deuterium exchange (HDX) dates back to the 1950s, when protein scientist Linderstrøm-Lang created a method involving protein deuteration to distinguish amide hydrogens participating in secondary structures. Today, scientists frequently rely on HDX data to investigate protein structure, conformational dynamics, and protein-ligand interaction.

Recombinant antibodies are artificially synthesized antibodies. Recombinant antibodies are generated from expression systems (e.g., E.coli, yeast, mammalian cell lines) via transfection with two separate plasmids encoding the amino acid sequences for the light and heavy chains, respectively. In order to recombinantly produce mAbs, the amino acid sequence of the light and heavy chains must be known. There are many ways to obtain the sequence of an antibody.
Since 2006, the One Health Initiative (OHI)’s goal has been to demonstrate the inextricable link between humans, animals, and the environment.

Peptide mapping is a widely used analytical technique to verify the primary structure (amino acid sequence) and characterize the chemical modifications of a protein. It analyzes peptides generated from the digestion of an isolated protein, or a protein mixture
Amino acids are small organic molecules that make up peptides and proteins. All living organisms share the same set of amino acids. Amino acids come together in different orders (sequences) to form proteins. As such, each type of protein has a different three-dimensional structure and biological activity.
Our team, along with four other industry panelists, discuss ways to safeguard their research through recombinant antibodies, cell culturing procedures, antibody protein sequences, and reference identifiers.
The transition from polyclonal antibody drugs to a more targeted monoclonal approach was made possible through a series of scientific and technological advancements; the most notable of which is the hybridoma technique developed by Köhler and Milstein, which allowed the generation of pure antibodies at scale.
Protein sequencing is a method that typically utilizes mass spectrometry (MS) to determine the amino acid code of a protein1. Prior to the development of mass spectrometry, Edman degradation, a method involving the stepwise degradation of peptides to derive the order of amino acids, was the mainstream approach. Nowadays, mass spectrometry is favored due to its ease of use and high throughput capabilities, though Edman degradation is still employed for specific applications in which the technique is well suited.
Monoclonal antibodies (mAbs) are homogenous antibodies that bind to a single epitope on an antigen. Kohler and Milstein generated the first mAbs when they developed hybridoma technology in the 1970s. Because of the specificity, homogeneity and unlimited availability, mAbs are valuable reagents used in a variety of important applications including treatment and diagnosis of diseases
Amino acids (aa)—the building blocks of proteins—are simple molecules characterized by a variable R group flanked either side by an amino group and a carboxyl group. With around 20 different commonly found amino acids, each one can bond with another to produce chains that can be classified as peptides (typically below 50 aa) and proteins (sequences above 50 aa)—molecules ubiquitous to every known organism.
Amino acid sequencing is commonly performed using Edman degradation or mass spectrometry (MS). While mass spectrometry is favoured for its high throughput capabilities and ease of use, both techniques possess their own features and limitations. This article summarizes some of the key pain points inherent in the two methodologies when determining the amino acid sequence.
Antibodies are used in a variety of ways in academia and industry, from tools to therapeutics. Because antibodies are produced using live processes, which are naturally error-prone, validation is required from time to time. Furthermore, to develop biological therapeutics, the protein sequence must be confirmed as part of the regulatory process.
DNA sequencing is the process of determining the precise order of four nucleotides bases—adenine (A), guanine (G), cytosine (C), and thymine (T)—that make up the DNA molecule. From Sanger sequencing to next-generation sequencing (NGS), DNA sequencing’s accessibility and ease of use make it one of the most widely used technologies in life sciences.
As proteins are assembled, they fold into different structural orders: from primary to quaternary. The exact sequence of the primary structure (the amino acid sequence) will dictate how a protein will fold and function. The importance of the primary structure has been noted in several studies, where changes in the original amino acid sequence have resulted in affinity problems, binding disruption, reduced half-life, and higher aggregation odds.
Proteins are composed of peptide chains, which in turn are made up of a string or linear sequence of amino acids. Every amino acid has a basic structure containing an amino (-NH2) group and a carboxylic (-COOH) group (Figure 1B). To form a peptide, amino acids link to each other via a peptide bond, which involves the reaction between the carboxylic group of one amino acid and the amine group of another amino acid.
Protein mass spectrometry refers to the use of mass spectrometry in studying and characterizing proteins, including their quantification, profiling, interaction mapping, and identification of their post-translational modifications. Protein mass spectrometry may also be referred to as mass spectrometry-based proteomics. Mass spectrometry-based proteomics comprises three approaches: top-down, middle-down, and bottom-up proteomics.
This webinar offers insight into how DNA and protein sequencing compare to each other.
Antibody sequences are critical for antibody engineering and protein characterization in therapeutic development. For antibody reagent users, knowing the sequences allows them to perform sequence analysis/alignment to identify binding and cross-reactivity so they can conduct rational experiment design.
Because they share the same mass, isoleucine and leucine are known as isobaric amino acids. Conventional mass spectrometry-based proteomics cannot be easily used to distinguish between isoleucine and leucine.
Amino acid sequencing is the process of identifying the arrangement of amino acids in proteins and peptides. Numerous distinct amino acids have been discovered in nature but all proteins in the human body are comprised of just twenty different types.
Bispecific therapeutics are monoclonal antibodies that carry a specific antigen-binding capability on each arm. Bispecifics are thus capable of having two specificities that can either double the binding affinity of the antibody toward the same antigen (increased avidity), or can now bind to two targets. Bispecifics are most often described as two types: trispecifics and bispecific T-cell engaged antibodies (BiTE).

Antibodies are integral to life sciences research and therapeutic and diagnostics discovery and development. However, they are inherently prone to variability.
Written by María Gerpe, PhD June 18, 2021 Introduction Research publications represent an additional source of validation proof for commercially available antibodies. As such, academic and industry scientists often also rely on publication references to decide which commercial antibody to purchase. Several independent efforts exist to compile such information. For instance, [...]
Over the past 5 years Rapid Novor has perfected monoclonal antibody sequencing, and is now sequencing mAbs from polyclonal mixtures using REpAb®. After successfully launching their proteogenomics based sequencing technology to deconvolute the immune response, the team has further evolved the technology and has derived the most abundant mAb sequences directly from rabbit blood using only proteomics. The talk will surround the development, progress and use cases for REpAb®.
Over the past several years Rapid Novor has been developing the world’s best antibody protein sequencing platform, sequencing over 2700 monoclonal antibodies and proteins.

Nowadays, DNA sequencing is so popular that it is easy to forget that the first sequenced biological material was protein – insulin, by Sanger. Sanger, and another researcher, Edman, separately pioneered protein sequencing.
In this on-demand webinar, we discuss why it is important to characterize antibodies based on their physical properties not just by what they bind, and how you can easily do the former via mass spectrometry-based protein sequencing.
One of the most important pieces of information researchers need to know during early stage antibody drug research and development is the sequence information of the antibody protein. With the advancement of mass spectrometry instrumentation and technologies, it is helpful, and sometimes critical, to conduct sequence analysis using mass spectrometry experiments.
Recombinant Monoclonal Antibodies (rAbs) are highly reproducible, customizable and pure alternatives to the traditional antibodies produced by hybridomas. Get the antibody protein sequence, either by DNA sequencing or the de novo protein sequencing technology, you can rest assured that you can have the exact antibody made recombinantly anytime in the future.
