Description
The protein encoded by this gene is essential for T-cell proliferation and survival, cytokine production, and T-helper type-2 development. Several alternatively spliced transcript variants encoding different isoforms have been found for this gene.
Bio-activity
Measured by its binding ability in a functional ELISA. When Recombinant Human/Cynomolgus Monkey/Rhesus Macaque CD28 Fc Chimera is coated at 1 μg/mL (100 μL/well), the concentration of Recombinant Human B7-1/CD80 Fc Chimera that produces 50% of the optimal binding response is approximately 0.05-0.3 μg/mL.
Storage
Use a manual defrost freezer and avoid repeated freeze-thaw cycles.
12 months from date of receipt, -20 to -70 centigrade as supplied.
1 month, 2 to 8 centigrade under sterile conditions after reconstitution.
3 months, -20 to -70 centigrade under sterile conditions after reconstitution.
