Reconstitute the lyophilized protein in sterile deionized water. The product concentration should not be less than 100 μg/ml. Before opening, centrifuge the tube to collect powder at the bottom. After adding the reconstitution buffer, avoid vortexing or pipetting for mixing.

Upon receiving, this product remains stable for up to 6 months at lower than -70°C. Upon reconstitution, the product should be stable for up to 1 week at 4°C or up to 3 months at -20°C. For long term storage it is recommended that a carrier protein (example 0.1% BSA) be added. Avoid repeated freeze-thaw cycles.

CD38 (also referred to as T10 antigen) is a nonlineage-restricted type II transmembrane glycoprotein that has emerged as an intracellular calcium ion mobilizing messenger. It can serve as an ectoenzyme that catalyzes the synthesis and hydrolysis of cyclic ADP-ribose. The enzymatic functions of CD38 probably contribute to an array of its immunoregulatory functions. It has been found on the surface of many immune cells (white blood cells), including CD4+, CD8+, B lymphocytes and natural killer cells. Soluble CD38 and the ability of membrane-bound CD38 to become internalized in response to appropriate stimuli suggest that extracellular and intracellular roles for this protein are equally plausible.
