Inducible T-Cell Costimulator Ligand also known as ICOSLG, is part of the B7 family of co-stimulatory molecules related to B7-1 and B7-2. ICOSLG is a transmembrane glycoprotein with extracellular IgV and IgC domains, in addition it binds to ICOS on activated T cells. The dependent signaling of ICOSLG takes part in a proliferative response.
ICOSLG produced in Sf9 Baculovirus cells is a single, glycosylated polypeptide chain containing 480 amino acids (19-256a.a.) and having a molecular mass of 53.7kDa (Molecular size on SDS-PAGE will appear at approximately 50-70kDa).
ICOSLG is expressed with a 239 amino acid hIgG-His-tag at C-Terminus and purified by proprietary chromatographic techniques.
Sf9, Baculovirus cells.
ICOSLG protein solution (1mg/ml) contains Phosphate Buffered Saline (pH 7.4) and 10% glycerol.
For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).
Avoid multiple freeze-thaw cycles.
Greater than 90.0% as determined by SDS-PAGE.
