Antibody Fragments
Fab and F(ab')₂ formats from Bio X Cell retain the antigen-binding specificity of trusted antibody clones while removing the Fc region, making them useful for applications where reduced Fc receptor engagement, reduced complement interaction, or smaller antibody formats are desired. These fragments are commonly used in functional in vivo and in vitro studies and also support antibody-directed delivery approaches, including conjugation or coupling to nucleic acid–containing particles. Because these fragments are generated from established Bio X Cell catalog antibodies, researchers can use well-characterized clones in a fragment format suited to their experimental needs.
Bio X Cell's Fab and F(ab')₂ are ultrapure (≥95% purity), low in endotoxin, and free from preservatives, stabilizers, and carrier proteins. Each product is accompanied by lot-specific Certificates of Analysis (CoAs), readily available for veterinarians, lab managers, and vivarium teams, ensuring transparency compliance and confidence in every experiment.
