  • 製品の概要

    Abcam’s beta 2 Microglobulin (B2M) Human ELISA (Enzyme-Linked Immunosorbent Assay) kit is an in vitro enzyme-linked immunosorbent assay for the quantitative measurement of Human beta 2 Microglobulin in serum, plasma and cell culture supernatants.

    This assay employs an antibody specific for Human beta 2 Microglobulin coated on a 96-well plate. Standards and samples are pipetted into the wells and beta 2 Microglobulin present in a sample is bound to the wells by the immobilized antibody. The wells are washed and biotinylated anti-Human beta 2 Microglobulin antibody is added. After washing away unbound biotinylated antibody, HRP-conjugated streptavidin is pipetted to the wells. The wells are again washed, a TMB substrate solution is added to the wells and color develops in proportion to the amount of beta 2 Microglobulin bound. The Stop Solution changes the color from blue to yellow, and the intensity of the color is measured at 450 nm.

    Get higher sensitivity in only 90 minutes with Human Beta-2-Microglobulin ELISA Kit (ab181423) from our SimpleStep ELISA® range.

  • 研究分野
  • 関連性Beta 2 Microglobulin non-covalently associates with the 44 kDa alpha chain to form the HLA Class I antigen complex. Human beta 2 Microglobulin associated with HLA Class I antigens are expressed on many types of cells including lymphocytes, thymocytes, monocytes, granulocytes, platelets, endothelial cells, and epithelial cells. It is absent on erythrocytes.

Product Wall

This kit has not been tested for cross-reactivity with mouse samples. However, since human and mouse Beta-2M differ by 30% in their primary sequence it is unlikely this kit will detect mouse Beta 2M.

Thank you for contacting us.

As you mention, the kit can be stored up to 6 months at temperatures between 4-8°C.

The standard is stable at these temperatures as long as it has not been reconstituted.

Once reconstituted...

Thank you for your inquiry.

I can confirm that serum/plasma samples usually require a 5,000˜100,000 fold dilution. I am sorry, I am unable to give a morenarrow range.

I agree that aserial dilutionis the best approach.
