Feline Immunodeficiency Virus (FIV) Antigen

A liquid, 1 mg antigen reagent from Antibodies.com supports ELISA-based workflows targeting Feline Immunodeficiency Virus (FIV) in feline diagnostic and research applications. FIV is a lentivirus in the Retroviridae family that causes progressive immune dysfunction in domestic cats, and reliable antigen reagents underpin both serological screening and viral protein studies.

Supplied ready-to-use in liquid form, the preparation can be diluted directly into coating buffer for plate-bound immunoassays, used as a positive control to verify antibody binding, or applied as an immunogen when raising anti-FIV reagents. Aliquoting upon receipt helps preserve activity and supports reproducible lot-to-lot comparisons across runs.

FIV shares structural and functional parallels with human immunodeficiency virus, including the gag, pol, and env gene products, making its antigens valuable in comparative retrovirology. Laboratories investigating viral tropism, receptor binding, or lentiviral pathogenesis can incorporate the antigen into ELISA plates to evaluate feline antibody responses following infection or vaccination. Diagnostic manufacturers building confirmatory tests for clinical veterinary labs, as well as academic groups characterizing feline immune responses, will find the 1 mg format practical for both assay development and ongoing screening programs.
