Endotoxin:
< 0.1 EU/μg of the protein by LAL method.
Purity:
≥ 95 % as determined by SDS-PAGE;≥95 % as determined by HPLC.
Formulation:
Lyophilized from a 0.22 μm filtered solution of PBS, pH 7.4.Contact us for customized product form or formulation.
Bio-Activity:
Measured by its binding ability in a functional ELISA. Immobilized Human CD38 Protein at 1μg/mL (100 μL/well) can bind CD38 Rabbit pAb with a linear range of 0.244-3.2 ng/mL.
Loaded CD38 Rabbit mAb (Catalog:A20215) on ProA Biosensor, can bind Human CD38 Protein, C-His (RPCB0248) with an affinity constant of 4.1 nM as determined in BLI assay (Gator).
Reconstitution:
Centrifuge the vial before opening. Reconstitute to a concentration of 0.1-0.5 mg/mL in sterile distilled water. Avoid vortex or vigorously pipetting the protein. For long term storage, it is recommended to add a carrier protein or stablizer (e.g. 0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose), and aliquot the reconstituted protein solution to minimize free-thaw cycles.
Storage:
Store at -20℃.Store the lyophilized protein at -20℃ to -80 ℃ up to 1 year from the date of receipt. After reconstitution, the protein solution is stable at -20℃ for 3 months, at 2-8℃ for up to 1 week.
The protein is a non-lineage-restricted, type II transmembrane glycoprotein that synthesizes and hydrolyzes cyclic adenosine 5'-diphosphate-ribose, an intracellular calcium ion mobilizing messenger. The release of soluble protein and the ability of membrane-bound protein to become internalized indicate both extracellular and intracellular functions for the protein. This protein has an N-terminal cytoplasmic tail, a single membrane-spanning domain, and a C-terminal extracellular region with four N-glycosylation sites. Crystal structure analysis demonstrates that the functional molecule is a dimer, with the central portion containing the catalytic site. It is used as a prognostic marker for patients with chronic lymphocytic leukemia.
