When purified anti-human CD38 antibody is immobilized at 1 µg/mL, recombinant human CD38 binds in a dose-dependent manner. HRP avidin (Cat. No. 405103) was used to detect the binding. -
Stability testing for Recombinant Human CD38. Recombinant human CD38 was aliquoted in PBS, pH 7.2 at 0.2 mg/mL. One aliquot was kept at 4°C (Control), and another was frozen and thawed four times (4x Freeze/Thaw). The samples were evaluated in a binding assay with immobilized purified anti-human CD38 antibody at 1 µg/mL and different concentration of human CD38 that binds in a dose-dependent manner. The EC50 range for this effect is 0.7 – 4.2 ng/mL.

CD38 is a 45 kD type II transmembrane glycoprotein also known as T10. It is an ADP-ribosyl hydrolase expressed at variable levels on hematopoietic cells and in some non-hematopoietic tissues (such as brain, muscle, and kidney). In humans, it is expressed at high levels on plasma cells and activated T and B cells, natural killer (NK) lymphocytes, myeloblasts, and erythroblasts. By functioning as both a cyclase and a hydrolase, CD38 mediates lymphocyte activation, adhesion, and the metabolism of cADPR and NAADP. CD31 is the ligand of CD38. ADP-ribosyl cyclase is able to transform NAD(P)+ into three different products with calcium mobilizing ability, cyclic ADP-ribose, NAADP+, and ADP-ribose.
Product DetailsProduct Details
- Source
- Biotinylated recombinant human CD38, amino acid Val 43 - Ile 300 (Accession No.NP_001766.2), with a C-terminal Avi-6His tag, was expressed in CHO cells. Human CD38-Avi tag was site-specifically biotinylated by enzyme BirA.
- Molecular Mass
- The 294 amino acid recombinant protein has a predicted molecular mass of approximately 33.5 kD. The DTT-reduced and non-reduced protein migrates at approximately 35 – 50 kD by SDS-PAGE. The predicted N-terminal amino acid is Val.
- Purity
- > 95%, as determined by Coomassie stained SDS-PAGE.
- Formulation
- 0.22 µm filtered protein solution is in PBS, pH7.2.
- Endotoxin Level
- Less than 0.1 EU per µg of protein as determined by the LAL method.
- Concentration
- 25 µg size is bottled at 200 µg/mL. 100 µg size and larger sizes are lot-specific and bottled at the concentration indicated on the vial. To obtain lot-specific concentration and expiration, please enter the lot number in our Certificate of Analysis online tool.
- Storage & Handling
- Unopened vial can be stored between 2°C and 8°C for up to 2 weeks, at -20°C for up to six months, or at -70°C or colder until the expiration date. For maximum results, quick spin the vial prior to opening. The protein can be aliquoted and stored at -20°C or colder. Stock solutions can also be prepared at 50 - 100 µg/mL in appropriate sterile buffer, carrier protein such as 0.2 - 1% BSA or HSA can be added when preparing the stock solution. Aliquots can be stored between 2°C and 8°C for up to one week and stored at -20°C or colder for up to 3 months. Avoid repeated freeze/thaw cycles.
- Activity
- Immobilized purified anti-human CD38 antibody at 1 µg/mL binds recombinant human CD38 in a dose-dependent manner. HRP avidin (Cat. No. 405103) was used to detect the binding. The ED50 for this effect is 0.7 – 4.2 ng/mL.
