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
Written by Yuning Wang, PhD, and María Gerpe, PhD IgBLAST Definition Developed by the National Center for Biotechnology Information (NCBI), IgBlast is a tool for the analysis of immunoglobulin and T cell receptor sequences in FASTA format. Using Basic Local Alignment Search Tool (BLAST) technology, IgBlast identifies similar sites within nucleotide or [...]
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.
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.
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, [...]
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.
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.
