Applications of Polyclonal Antibodies Challenges of Polyclonal Antibodies De Novo Polyclonal Antibody Sequencing Introduction Polyclonal antibodies (pAbs) are a heterogeneous mix of antibodies derived from B cells in the adaptive immune system.

Circulating in blood is a multitude of biologically important antibodies. These pools of polyclonal antibodies (pAb) are invaluable sources for drug discovery against various diseases, and for the development of robust immunoreagents for diagnostics, and research.
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.
Written by María Gerpe, PhD July 23, 2021 Why the Amino Acid Sequence Matters 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 therefore function. The importance of [...]
Antibodies are integral to life sciences research and therapeutic and diagnostics discovery and development. However, they are inherently prone to variability.
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.
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, [...]
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.
