Parainfluenza Virus type 1 (PIV-1) Grade 2 Ag

Partially purified and concentrated by centrifugation, this 1 ml Grade 2 antigen preparation targets Parainfluenza Virus type 1 (PIV-1), a leading cause of croup, bronchiolitis, and viral pneumonia in young children. Antibodies.com supplies the material for EIA workflows used in respiratory virus surveillance, serological testing, and immunoassay development. PIV-1 antigens are commonly incorporated into multiplexed respiratory pathogen panels or used as coating antigens in microplate-based detection systems targeting the viral HN and F glycoproteins. Reference laboratories, vaccine researchers, and public health teams handling nasopharyngeal specimens rely on characterized viral antigens to validate antibody cross-reactivity, establish positive controls, and standardize assay performance. The single-use vial format supports reproducible downstream applications, and handling guidance provided with the shipment helps preserve conformational epitopes critical for antibody recognition across respiratory diagnostics pipelines.
