- Weitere Details:
- Beta-2-microglobulin (B2M) is found in the serum of normal individuals and in the urine in elevated amounts in patients with Wilson disease, cadmium poisoning, and other conditions leading to renal tubular dysfunction. Like immunoglobulins, prealbumin, and the beta protein found in the amyloid of Alzheimer disease, B2M has a predominantly beta-pleated sheet structure that may adopt the fibrillar configuration of amyloid in certain pathologic states. The protein is a single polypeptide chain of molecular weight 11,600 (human 119aa, chromosome 15). B2M associates with heavy chain of class I MHC antigens on the cell surface. A transient complex of MHC-heavy chain and B2M is known to be assembled into the TAP molecule involving interation with a number of chaperones. Binding of the processed peptide releases the class I-B2M complex to the cell surface. Absence of binding leads to degradation in the proteasome. Progressive hepatic iron overload, indistinguishable from that observed in HFE, was found only in mice homozygous for the mutated B2M gene. Applications: Suitable for use in ELISA. Other applications not tested. Recommended Dilutions: Optimal dilutions to be determined by the researcher. Storage and Stability: May be stored at 4°C for short-term only. Aliquot to avoid repeated freezing and thawing. Store at -20°C. Aliquots are stable for 12 months after receipt. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap.
