Human Integrin alpha M beta 2 (ITGAM&ITGB2) Heterodimer Protein, His Tag&Tag Free (MALS verified)

Integrin ITGAM/ITGB2 is implicated in various adhesive interactions of monocytes, macrophages and granulocytes as well as in mediating the uptake of complement-coated particles and pathogens. It is identical with CR-3, the receptor for the iC3b fragment of the third complement component. It probably recognizes the R-G-D peptide in C3b. Integrin ITGAM/ITGB2 is also a receptor for fibrinogen, factor X and ICAM1. It recognizes P1 and P2 peptides of fibrinogen gamma chain. In association with beta subunit ITGB2/CD18, required for CD177-PRTN3-mediated activation of TNF primed neutrophils. May regulate phagocytosis-induced apoptosis in extravasated neutrophils. May play a role in mast cell development. Required with TYROBP/DAP12 in microglia to control production of microglial superoxide ions which promote the neuronal apoptosis that occurs during brain development.

Human ITGAM&ITGB2 Heterodimer Protein, His Tag&Tag Free, produced by co-expression of ITGAM and ITGB2, has a calculated MW of 127.2 kDa (ITGAM) and 80.2 kDa (ITGB2) . Subunit ITGAM is fused with an acidic tail at the C-terminus and followed by a polyhistidine tag and subunit ITGB2 contains no tag but a basic tail at the C-terminus. The non-reducing (NR) protein migrates as 150-180 kDa (ITGAM) and 90-100 kDa (ITGB2) respectively due to glycosylation.

● -20°C to -70°C for 12 months in lyophilized state; ● -70°C for 3 months under sterile conditions after reconstitution. For long term storage, the product should be stored at lyophilized state at -20°C or lower.
