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

Supplied as a 1 ml vial of Grade 2 material, this partially purified Parainfluenza Virus type 2 antigen from Antibodies.com is concentrated by centrifugation to enrich viral components for use as coating or control material in enzyme immunoassays. The antigen is intended for EIA applications and supports the development of respiratory pathogen detection assays targeting PIV-2, one of the four recognized human parainfluenza serotypes associated with croup, bronchiolitis, and lower respiratory tract infections, particularly in pediatric populations. The Grade 2 designation reflects a partially purified preparation suitable for diagnostic kit manufacturing and serological research where high purity is not strictly required. Researchers working on respiratory virus surveillance, vaccine development, and diagnostic assay validation can integrate this antigen into immunoassay workflows as a positive control or a calibrator.
