Infectious Peritonitis Virus, Feline (FIPV) Ag

The feline infectious peritonitis virus (FIPV) antigen from Antibodies.com is a liquid preparation supplied at 1 mg for incorporation into ELISA workflows. FIPV, a pathogenic feline coronavirus biotype, causes feline infectious peritonitis, a systemic and frequently fatal disease in domestic cats. The antigen provides defined viral epitopes recognized by feline antibodies, supporting serological assays that probe immune responses to natural infection or experimental immunization.

Primary use cases include developing and validating diagnostic immunoassays for FIP screening, profiling antibody titers in clinical feline samples, and serving as a reference reagent in studies of coronavirus tropism, replication, and immune evasion. Veterinary diagnostic laboratories and academic research groups studying feline virology, mucosal immunity, and coronavirus pathogenesis employ this antigen during assay development and characterization phases.

The liquid formulation permits direct dilution into coating buffers for microplate adsorption, and the material should be stored frozen in aliquots to preserve antigenicity over multiple experiments. Each vial supports consistent batch-to-batch performance when handled to limit repeated freeze-thaw cycles. This reagent is intended for research use only in laboratory settings and is supplied as a single-use format suitable for downstream immunoassay work, viral neutralization studies, and immunization protocols in appropriate animal models.
