Human CD58 / LFA-3 Protein, Fc Tag

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) [3] 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.

Product Specifications

Background

Specifications

This protein carries a human IgG1 Fc tag at the C-terminus. The protein has a calculated MW of 48.1 kDa. The protein migrates as 60-70 kDa under reducing (R) condition, and 150 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under non-reducing (NR) condition (SDS-PAGE) due to different glycosylation.
