ICOS Ligand (CD275, Inducible T cell co-stimulator ligand, B7-H2, B7 homolog 2, B7-like protein Gl50, B7 related protein 1, B7H2, B7RP-1, B7RP1, GL50, ICOS LG , ICOSLG, KIAA0653, LICOS, Transmembrane protein B7 H2 ICOS ligand)
Description:
B7-H2 is detected on the surface of monocyte derived immature dendritic cells. It is a putative ligand for ICOS (inducible costimulator) from CD28 family of T cell-costimulators. Costimulatory interactions between the B7 family ligands and their receptors like CD28, CTLA-4 and ICOS play critical role in the growth, differentiation and death of T cells. B7-H2 has four conserved structural cysteins in its extracellular domain which are believed to form the Ig V like and IgC-like domain. In addition, B7-H2 has a conserved tyrosine residue in the Ig V-like domain at position of aa80. B7-H2 shares ~46% homology at amino acid level to B7h/B7RP-1, a recently described B7 like protein of mouse origin.

Applications:
Suitable for use in Flow Cytometry. Other applications not tested.

Recommended Dilutions:
Flow Cytometry: Tested on BOSC cells transiently transfected with an ICOS Ligand expression vector.
Optimal conditions to be determined by the researcher.

Storage and Stability:
May be stored at 4C for short-term only. For long-term storage and to avoid repeated freezing and thawing, add sterile glycerol (40-50%), aliquot and store at -20C. Aliquots are stable for at least 12 months at -20C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
