MW: 22.7 kDa

Purity: Greater than 95% as determined by SEC-HPLC. Greater than 95% as determined by SDS-PAGE.

Endotoxin: Less than 1.0 EU/μg as determined by LAL method.

Biological_Activity: 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℃/-80℃. Our default final concentration of glycerol is 50%. Customers could use it as reference.

Storage: 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℃/-80℃. The shelf life of lyophilized form is 12 months at -20℃/-80℃.

Notes: Repeated freezing and thawing is not recommended. Store working aliquots at 4℃ for up to one week.

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.
