Recombinant Human CD7/GP40 Protein (His Tag)

T-Cell Antigen CD7 is a single-pass type I membrane protein that that belongs to the the immunoglobulin superfamily. Human CD7 is synthesized as a 240 amino acid precursor that contains a 25 amino acid signal sequence and a 215 amino acid mature chain with a Ig-like (immunoglobulin-like) domain. CD7 is normally expressed on all T-lymphocytes; NK-cells; pre-B lymphocytes and pleuripotent hematopoietic stem cells. CD7 plays an essential role in T-cell interactions; T-cell/B-cell interaction during early lymphoid development; T- and NK-cell activation and cytokine production. CD7 has been shown to interact with PIK3R1and SECTM1. However; the function of the CD7 protein in the immune system is still largely unknown.

Generally, lyophilized proteins are stable for up to 12 months when stored at -20 to -80°C. Reconstituted protein solution can be stored at 4-8°C for 2-7 days. Aliquots of reconstituted samples are stable at < -20°C for 3 months.
