Relevance
CD2 interacts with lymphocyte function-associated antigen CD58 (LFA-3) and CD48/BCM1 to mediate adhesion between T-cells and other cell types. CD2 is implicated in the triggering of T-cells, the cytoplasmic domain is implicated in the signaling function.
Endotoxin
Less than 1.0 EU/μg as determined by LAL method.
Purity
Greater than 95% as determined by SEC-HPLC. Greater than 95% as determined by SDS-PAGE.
Activity
Yes
Bioactivity
Measured by its binding ability in a functional ELISA. Immobilized Human CD2 at 5 μg/mL can bind Human CD58 (CSB-MP6138HUj8-B) . The EC50 is 337.0-430.1 ng/mL.
Form
Lyophilized powder
Buffer
Lyophilized from a 0.2 μm sterile filtered PBS, 6% Trehalose, pH 7.4
Reconstitution
We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Please reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg/mL.We recommend to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20°C/-80°C. Our default final concentration of glycerol is 50%. Customers could use it as reference.
Molecular Weight
22.7 kDa

Storage Conditions
The shelf life is related to many factors, storage state, buffer ingredients, storage temperature and the stability of the protein itself. Generally, the shelf life of liquid form is 6 months at -20°C/-80°C. The shelf life of lyophilized form is 12 months at -20°C/-80°C.
