What is Peptide Mapping?

2022-04-25T20:15:08-04:00October 28th, 2021|Articles|

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

Antibody Validation and its Use Cases

2022-04-25T18:20:45-04:00August 4th, 2021|Articles|

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.

Why Verifying the Protein Sequence Is Crucial for Antibody Validation

2022-04-25T19:13:45-04:00July 23rd, 2021|Articles|

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 [...]

Major Antibody Databases and Their Applications

2022-04-25T19:04:14-04:00June 18th, 2021|Articles|

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, [...]
