Descripción general

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[1]. 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.

Aplicación

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[2]
  • microneutralization assay[3]
  • single radial hemolysis (SRH) repeatability assay[4]

Cantidad

Each vial contains at least 25 mg protein

Reconstitución

Reconstitute with 0.5 mL deionized water.

Questions

1–2 of 2 Questions  
  1. Are the serum proteins of human complement cascade still active in the product S5393?

    1 answer
    1. The presence of complement components and the activation cascade have not been investigated for this product. This is not included in the quality testing. However, the serum has not been heat inactivated. In theory, serum complement should still be present and the cascade system can be activated. The end user would have to determine the suitability of this product for compliment studies.

  2. How is the serum treated to deplete it from IgG, IgA and IgM?

    1 answer
    1. Methods of preparation are considered proprietary.
