Product Description
The inducible costimulator (ICOS, T cell activation molecule H4) is similar to human CD28 (24% homology), and plays an analogous role in the T cell activation process. Each secondary signal from CD28 or ICOS results in a discrete cytokine secretion profile displayed by the activated T cell. 1 Both activation processes are effectively down regulated by CD152 (CTLA-4) engagement.2 Human GL50 is a member of the B7 family sharing ~20% homology with CD80 (B7-1) and CD86 (B7-2), and has been shown to be a ligand for ICOS.3 ICOS-muIg recombinant protein binds to recombinant GL50-muIg in EIA. Functional Application: ICOS-muIg binds to recombinant GL50-muIg in EIA. Human ICOS-muIg Fusion Protein*l Molecular Structure: A soluble molecule consisting of the extracellular (121aa) domain of mature human ICOS fused to the murine IgG2a Fc (232 aa). Transfectant Cell Line: CHO Applications: Suitable for use in Flow Cytometry, ELISA. Other applications not tested. Recommended Dilution: Optimal dilutions to be determined by the researcher. Storage and Stability: May be stored at 4C. For long-term storage, aliquot and store at 4C. Do not freeze. Aliquots are stable for at least 6 months. For maximum recovery of product, centrifuge the original vial prior to removing the cap. Further dilutions can be made in assay buffer.
