Recombinant Human CD58 protein, His-tagged

Specification :
| Description : CD antigen CD58 is also known as Lymphocyte function-associated antigen 3 (LFA-3). CD58 is a cell adhesion molecule expressed on Antigen Presenting Cells (APC), particularly macrophages. CD58/LFA3 is ligand of the T-lymphocyte CD2 glycoprotein, which binds to CD2 (LFA-2) on T cells and is important in strengthening the adhesion between the T cells and Professional Antigen Presenting Cells. In addition, the LFA-3/CD2 interaction may prime response by both the CD2+ and LFA-3+ cells. Polymorphisms in the CD58 gene are associated with increased risk for multiple sclerosis. | Source : HEK293 | Species : Human | Tag : His | Predicted N Terminal : Phe29 | Form : Lyophilized from 0.22 μm filtered solution in PBS, pH7.4, 10% trehalose. | Molecular Mass : The protein has a calculated MW of 22.3 kDa. The protein migrates as 30-45 kDa under reducing (R) condition (SDS-PAGE) due to differtent glycosylation. | Protein length : Phe29-Arg215 | Endotoxin : Less than 1.0 EU per μg by the LAL method. | Purity : >95% as determined by SDS-PAGE. | Storage : For long term storage, the product should be stored at lyophilized state at -20 centigrade or lower.Please avoid repeated freeze-thaw cycles.This product is stable after storage at:-20 to -70 centigrade for 12 months in lyophilized state;-70 centigrade for 3 months under sterile conditions after reconstitution. | Reconstitution : It is recommended that sterile water be added to the vial to prepare a stock solution of 0.2 ug/ul. Centrifuge the vial at 4℃ before opening to recover the entire contents.
