Human Integrin alpha M beta 2 (ITGAM&ITGB2) Heterodimer Protein
Recombinant Human Integrin alpha M beta 2 (ITGAM&ITGB2) Heterodimer Protein is expressed from HEK293 with His tag at the C-Terminus of ITGAM.It contains Phe17-Asn1104 (ITGAM) acidic tail and Gln23-Asn700(H354Q) (ITGB2) basic tail [Accession | P11215-1 (ITGAM) & P05107-1(H354Q) (ITGB2)].
The protein has a predicted MW of 126.10 kDa (ITGAM) and 79.50 kDa (ITGB2). Due to glycosylation, the protein migrates to 140-160 kDa (ITGAM) and 90-100 kDa (ITGB2) based on Bis-Tris PAGE result.
> 90% as determined by Bis-Tris PAGE
Less than 1 EU per μg by the LAL method.
Lyophilized from 0.22 μm filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization.
Dissolve the lyophilized protein in distilled water. Please refer to the Certificate of Analysis for detailed instructions.
-20 to -80°C for 12 months as supplied from date of receipt.
-80°C for 3 months after reconstitution.
Recommend to aliquot the protein into smaller quantities for optimal storage. Please minimize freeze-thaw cycles.
Integrin αMβ2, also called Mac-1 or complement receptor-3 (CR3), is a heterodimer expressed on monocytes. It functions as both an adhesion molecule mediating the diapedesis of leukocytes across the endothelium and a receptor for the iC3b fragment of complement responsible for phagocytic/degranulation responses to microorganisms[1]. Active αMβ2 binds iC3b, coagulation proteins fibrinogen, plasminogen and factor X, extracellular matrix (ECM) proteins fibronectin, laminin and collagen, and cell surface ICAMs, myelin basic protein and DCSIGN[2].
