It shares several characteristics with ADP-ribosyl cyclase 2 CD157. CD38 is a multifunctional ectoenzyme that catalyzes the synthesis and hydrolysis of cyclic ADP-ribose (cADPR) from NAD+ to ADP-ribose. It also functions in cell adhesion, signal transduction and calcium signaling. CD38 has been used as a prognostic marker in leukemia. It can also be used to identify plasma cells. This enzyme is validated for CD38 Enzymatic activity application.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"font-size: 18px\"\u003e\u003cstrong\u003e\u003cu\u003eProduct Details\u003c\/u\u003e\u003c\/strong\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cu\u003eSource:\u003c\/u\u003e Mouse\u003c\/p\u003e\n\u003cp\u003e\u003cu\u003eExpression system:\u003c\/u\u003e HEK293 Cells.\u003c\/p\u003e\n\u003cp\u003e\u003cu\u003eProtein Construction:\u003c\/u\u003e Met1-Thr304 with a C terminal 6 His tag.\u003c\/p\u003e\n\u003cp\u003e\u003cu\u003eUniProt No:\u003c\/u\u003e P56528\u003c\/p\u003e\n\u003cp\u003e\u003cu\u003eAlternative Names:\u003c\/u\u003e ADP-ribosyl cyclase\/cyclic ADP-ribose hydrolase 1, CD38, ADPRC 1, ADPRC1.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"font-size: 18px\"\u003e\u003cstrong\u003e\u003cu\u003eProduct Specification\u003c\/u\u003e\u003c\/strong\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cu\u003eN Terminal Sequence Analysis:\u003c\/u\u003e Leu 45.\u003c\/p\u003e\n\u003cp\u003e\u003cu\u003ePredicted Molecular Weight:\u003c\/u\u003e 31.3 kDa (271aa)\u003c\/p\u003e\n\u003cp\u003eSDSPAGE: 38-42 kDa in SDS-PAGE under reducing conditions.\u003c\/p\u003e\n\u003cp\u003e\u003cu\u003eConcentration:\u003c\/u\u003e 1mg\/ml.\u003c\/p\u003e\n\u003cp\u003e\u003cu\u003eFormulation:\u003c\/u\u003e Liquid in 50mM MES buffer (pH 6.5) containing 100mM NaCl, 10% glycerol.\u003c\/p\u003e\n\u003cp\u003e\u003cu\u003eConcentration:\u003c\/u\u003e 1mg\/mL.\u003c\/p\u003e\n\u003cp\u003e\u003cu\u003ePurity:\u003c\/u\u003e \u0026gt; 95% by SDS-PAGE.\u003c\/p\u003e\n\u003cp\u003e\u003cu\u003eTag:\u003c\/u\u003e His-Tag.\u003c\/p\u003e\n\u003cp\u003e\u003cu\u003eBiological Activity:\u003c\/u\u003e Measured by its ability to convert the substrate nicotinamide guanine dinucleotide (NGD+) to cyclic GDP ribose.
