General description

Serum is the liquid component of blood that includes proteins, immunoglobulin and electrolytes. The product can be used for selective removal of contaminating antibodies when immobilized on a solid matrix. This product can also be used in anti-protective antigen (anti-PA) IgG measurements using PA coupled microspheres. Human serum deficient of IgG, IgA, and IgM can react specifically with anti-human whole serum but does not show reactivity with anti-human IgG, IgA, or IgM.

Application

Serum minus IgA/IgM/IgG human has been used as a control serum in immunoelectrophoresis, immunodiffusion,enzyme linked immunosorbent assay. It has also been used as
  • control sera to assess neuraminidase inhibition
  • microneutralization assay
  • single radial hemolysis (SRH) repeatability assay

Quantity

Each vial contains at least 25 mg protein

Reconstitution

Reconstitute with 0.5 mL deionized water.

The hemagglutination inhibition (HAI) assay is an established technique for assessing influenza immunity, through measurement of antihemagglutinin antibodies. Improved reproducibility of this assay is required to provide meaningful data across different testing laboratories. This study assessed the impact of harmonizing
