July 2018—Binding Site’s Immunologicals Group has added three parainfluenza virus antigens for in vitro diagnostic manufacturing and research applications. The Parainfluenza Virus Type 1, Type 2, and Type 3 antigens have been designed for use in solid phase enzyme immunoassay test procedures, especially ELISAs. The antigens exhibit exceptional purity levels as a result of chromatographic manufacturing techniques while demonstrating exceptional lot-to-lot consistencies and high degrees of activity and specificity, the company says. The Immunologicals Group also added two polyclonal sheep anti-human, affinity-purified, fluorescein isothiocyanate–conjugated, monkey-adsorbed antibodies for use in a variety of testing procedures, especially enzyme immunoassays. The anti-immunoglobulin antibody and the anti-IgG Fc targeted antibody demonstrate minimal species cross-reactivity with monkey serum proteins due to insoluble adsorption techniques used during manufacturing.
