B7-CD28ファミリー：免疫調節における重要な共刺激経路

Immobilized Human ICOS, Fc Tag (Cat. No. ICS-H5258) at 1 μg/mL (100 μL/well) can bind Human B7-H2, His Tag (Cat. No. B72-H5221) with a linear range of 5-78 ng/mL (QC tested).             
 

Serial dilutions of Ipilimumab were added into Human CTLA-4, Fc Tag (Cat. No. CT4-H5255): Biotinylated Human B7-1, Fc,Avitag (Cat. No. B71-H82F2) binding reactions. The half maximal inhibitory concentration (IC50) is 0.8260 μg/mL (Routinely tested).

Flow Cytometry assay shows that Biotinylated Human B7-1, Fc,Avitag (Cat. No. B71-H82F2) can bind to 293 cell overexpressing human CTLA-4. The concentration of Human B7-1 is 0.3 μg/mL (Routinely tested).
 
 

FACS analysis shows that the binding of Biotinylated Human B7-1, Fc,Avitag (Cat. No. B71-H82F2) to 293 overexpressing CTLA-4 was inhibited by increasing concentration of neutralizing Anti-Human CTLA-4 antibody. The concentration of B7-1 used is 0.3 μg/mL. The IC50 is 3.025 μg/mL (Routinely tested).

Human B7-H3 (4Ig), His Tag (Cat. No. B7B-H52E7) inhibits Anti-CD3-induced proliferation of PBMC. The EC50 for this effect is 7.95 μg/mL (Routinely tested).

Immobilized cell surface PD-1 (5x104 of cells per well) can bind Human PD-L1, Fc Tag (Cat. No. PD1-H5258) with an EC50 of 0.029 μg/mL (Routinely tested).
