Purity |
> 95% as determined by Bis-Tris PAGE |
Endotoxin Level |
Less than 1 EU per μg by the LAL method. |
Biological Activity |
Measured by its binding ability in a functional ELISA. Immobilized Integrin alpha M beta 2 (ITGAM&ITGB2) Heterodimer, His, Human at 2μg/ml (100 μl/well) on the plate can bind AntiITGB2 Antibody, hFc Tag. Test result was comparable to standard batch. |
Expression System |
HEK293 |
Theoretical Molecular Weight |
126.10 kDa (ITGAM) and 79.50 kDa (ITGB2) |
Apparent Molecular Weight |
Due to glycosylation, the protein migrates to 140-160 kDa (ITGAM) and 90-100 kDa (ITGB2) based on Bis-Tris PAGE result. |
Formulation |
Lyophilized from 0.22 μm filtered solution in PBS (pH 7.4). |
Reconstitution |
Centrifuge the tube before opening. Reconstituting to a concentration more than 100 μg/ml is recommended. Dissolve the lyophilized protein in distilled water. |
Storage & Stability |
Upon receiving, the product remains stable up to 6 months at -20 °C or below. Upon reconstitution, the product should be stable for 3 months at -80 °C. Avoid repeated freeze-thaw cycles. |
Target Background |
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]. |
