Active Recombinant Human CD38 protein, His/Avi-tagged, Biotinylated

• Cat.No.: CD38-051H
• Product Overview: Biotinylated Recombinant Human CD38(Val43-Ile300) protein, fused to His/Avi tag at the C-terminus, was expressed in HEK293 cells .

Specification

• Species: Human
• Source: HEK293
• Tag: Avi&His
• Protein Length: Val43-Ile300
• Description: CD38, also known as ADP-ribosyl cyclase, is a Type II integral membrane protein. The enzyme is able to transform NAD(P)+ into three different products with calcium mobilizing ability, cyclic ADP-ribose, NAADP+, and ADP-ribose (1). CD38 is expressed in B and T lymphocytes, osteoclasts, and in cardiac, pancreatic, liver and kidney cells (2, 3). Through its production of cyclic ADP-ribose, CD38 modulates calcium-mediated signal transduction in many types of cells, including neutrophils and pancreatic beta cells (4, 5). Our Avi-tag Biotinylated Recombinant Human CD38 features biotinylation at a single site contained within the Avi-tag, a unique 15 amino acid peptide. Protein orientation will be uniform when bound to streptavidin-coated surface due to the precise control of biotinylation and the rest of the protein is unchanged so there is no interference in the protein's bioactivity.
• Predicted N Terminal: Val43
• Form: Supplied as a 0.2 μm filtered solution in PBS.
• Bio-activity: Measured by its ability to convert the substrate nicotinamide guanine dinucleotide (NGD+) to cyclic GDP-ribose.
  The specific activity is >1500 pmol/min/μg, as measured under the described conditions.
  Measured by its binding ability in a functional ELISA.
  When Human CD38 Antibody is immobilized at 1 µg/mL (100 µL/well), it binds to Biotinylated Recombinant Human CD38
  His-tag Avi-tag with an ED50 of 1-6 ng/mL.
• Molecular Mass: 40-52 kDa, under reducing conditions
