Next Generation Protein Sequencing in Veterinary Medicine and Industry

2022-07-05T14:24:01-04:00December 3rd, 2021|Whitepapers|

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

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.

What are Monoclonal Antibodies?

2022-04-25T18:42:59-04:00August 25th, 2021|Articles|

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

De Novo Protein Sequencing vs DNA Sequencing

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 [...]

What is Protein Mass Spectrometry?

2022-04-25T15:22:40-04:00July 18th, 2021|Articles|

Protein mass spectrometry refers to the use of mass spectrometry in the study and characterization of proteins, including their quantification, profiling, interaction mapping, and identification of their post-translational modifications (1,2). Protein mass spectrometry may also be referred to as mass spectrometry-based proteomics. Mass spectrometry-based proteomics consist of three approaches: top-down, middle-down, and bottom-up proteomics

How do You Obtain the Sequence of an Antibody?

2022-04-18T20:18:42-04:00July 10th, 2021|Articles|

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.

Moving Towards Recombinant Monoclonal Antibodies

2021-12-14T18:06:16-05:00June 30th, 2016|Articles|

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.
