products name syn :
[BMG; B2MG]
other names :
[beta-2-microglobulin; Beta-2-microglobulin; beta-2-microglobulin; beta-2-microglobulin]
products gene name :
[b2M]
other gene names :
[B2M; B2M]
uniprot entry name :
B2MG_HUMAN
specificity :
This assay has high sensitivity and excellent specificity for detection of Beta-2-Microglobulin (b2M). No significant cross-reactivity or interference between Beta-2-Microglobulin (b2M) and analogues was observed.
storage stability :
The stability of kit is determined by the loss rate of activity. The loss rate of this kit is less than 5% within the expiration date under appropriate storage condition. To minimize extra influence on the performance, operation procedures and lab conditions, especially room temperature, air humidity, incubator temperature should be strictly controlled. It is also strongly suggested that the whole assay is performed by the same operator from the beginning to the end.

products description :
The test principle applied in this kit is Sandwich enzyme immunoassay. The microtiter plate provided in this kit has been pre-coated with an antibody specific to Beta-2-Microglobulin (b2M). Standards or samples are then added to the appropriate microtiter plate wells with a biotin-conjugated antibody specific to Beta-2-Microglobulin (b2M). Next, Avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. After TMB substrate solution is added, only those wells that contain Beta-2-Microglobulin (b2M), biotin-conjugated antibody and enzyme-conjugated Avidin will exhibit a change in color. The enzyme-substrate reaction is terminated by the addition of sulphuric acid solution and the color change is measured spectrophotometrically at a wavelength of 450nm 10nm. The concentration of Beta-2-Microglobulin (b2M) in the samples is then determined by comparing the O.D. of the samples to the standard curve.

ncbi summary :
This gene encodes a serum protein found in association with the major histocompatibility complex (MHC) class I heavy chain on the surface of nearly all nucleated cells. The protein has a predominantly beta-pleated sheet structure that can form amyloid fibrils in some pathological conditions. The encoded antimicrobial protein displays antibacterial activity in amniotic fluid. A mutation in this gene has been shown to result in hypercatabolic hypoproteinemia.[provided by RefSeq, Aug 2014]
uniprot summary :
B2M: Component of the class I major histocompatibility complex (MHC). Involved in the presentation of peptide antigens to the immune system. Heterodimer of an alpha chain and a beta chain.
