产品说明
一般描述
SILu™ Lite B2M is a recombinant human protein expressed in human 293 cells. It is a monomer of 119 amino acids (including C-terminal polyhistidine and flag tags), with a molecular weight of ~14 kDa. SILu™ Lite B2M is an analytical standard designed to be used as starting material for preparation of calibrators and controls in LC-MS applications.

生化/生理作用
B2M is the light chain of the major histocompatibility class (MHC) I molecule expressed on the cell surface of all nucleated cells. Increased urinary B2M excretion has been observed to be an early marker of tubular injury in a number of settings, including nephrotoxicant exposure, cardiac surgery, and renal transplantation, preceding rises in serum creatinine by as many as 4−5 days. B2M may also serve as an early biomarker for AKI (Acute Kidney Injury).
