To develop robust mAb biologics, it is vital to fully characterize the protein, including its primary sequence, mutations, and important post-translational modifications
Since 2006, the One Health Initiative (OHI)’s goal has been to demonstrate the inextricable link between humans, animals, and the environment. Certainly, the current global pandemic is a great testament to the ties between climate change, humans, and animals that OHI has been working to highlight. The rise of other zoonotic diseases (e.g., Hendra, and Nipah viruses) not only directly affect humans through disease transmission but may also result in deep impacts to the food supply

In this study, we conducted a large-scale statistical analysis of protein sequencing data from samples digested with multiple proteases to understand the impact of using different combinations of proteases to improve the depth of sequence coverage in the application of de novo protein sequencing.
Anti-drug antibody (ADA) assays are critical to assess the clinical efficacy and safety of a biological drug and rely on control reagents that mimic the ADA response to the biological drug being tested. These positive controls typically consist of animal-derived pooled polyclonal antibodies or human monoclonal antibody reference panels against the target protein drug.

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.
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.
Written by Yuning Wang, PhD August 1, 2021 What is DNA Sequencing? 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 [...]

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.
Monoclonal antibodies (mAbs) are widely used in research, diagnosis, and pharmaceutical purposes. Lately, the relatively lower quality of research-purpose mAbs is a point of concern within the research community.

The DNA sequences of antibodies are highly diverse due to the V-(D)-J recombination and hypersomatic mutations. As such, relying on homology-based searches to sequence novel antibodies can introduce bias to sequences obtained from proteomics approaches.

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.
