  • Product overview

    The CD14 ELISA is to be used for the in-vitro quantitative determination of CD14 in serum, plasma, or cell lysates. The assay will recognize both natural and recombinant CD14. This kit has been configured for research use only and is not to be used in diagnostic procedures.

    Principle

    The CD14 Kit is a solid phase sandwich Enzyme Linked-Immuno-Sorbent Assay (ELISA). A monoclonal antibody specific for CD14 has been coated onto the wells of the microtiter strips provided. Samples, including standards of known CD14 concentrations and unknowns are pipetted into these wells.

    During the first incubation, the CD14 antigen is added to wells. After washing, a biotinylated monoclonal antibody specific for CD14 is incubated. Then the enzyme (streptavidin-peroxydase) is added. After incubation and washing to remove all unbound enzyme, a substrate solution which acts on the bound enzyme is added to induce a coloured reaction product. The intensity of this coloured product is directly proportional to the concentration of CD14 present in the samples.

     

    Recognizes both natural and recombinant human CD14

    Range: 6.8 ng/ml - 220 ng/ml

    Sensitivity < 6 ng/ml

  • Notes

    Safety Information:

    • For research use only.
    • The human blood components included in this kit have been tested and found non reactive for HBsAg and anti-HIV. Nevertheless, no known method can offer complete assurance that human blood derivatives will not transmit hepatitis, AIDS or other infections. Therefore, handling of reagents, serum or plasma specimens should be in accordance with local safety procedures , e.g. CDC/NIH Health manual : "Biosafety in Microbiological and Biomedical Laboratories" 1984.
    • Avoid any skin contact with H2SO4 and TMB. In case of contact, wash thoroughly with water.
    • Do not eat, drink, smoke or apply cosmetics where kit reagents are used.
    • Do not pipette by mouth.
    • The stop solution in this kit contains 9.8% sulphuric acid.

  • Research Areas
  • RelevanceCD14 is a single copy gene encoding 2 protein forms: a 50 to 55 kDa glycosylphosphatidylinositol anchored membrane protein (mCD14) and a monocyte or liver derived soluble serum protein (sCD14) that lacks the anchor. Both molecules are critical for lipopolysaccharide (LPS) dependent signal transduction, and sCD14 confers LPS sensitivity to cells lacking mCD14. Increased sCD14 levels are associated with inflammatory infectious diseases and high mortality in gram negative shock.

    Thanks for your reply.

    The lab has already re-tested the lot you are using and found it to be within the CoA guidelines for their testing criteria. So I don't think it would be so useful to re-test one of the kits you have purchased.
