Target Name: 
Human CD38, T10, ADP­ribosyl cyclase, 
Source: 
Human CD38 protein (NP_001766.2) (Val43-Ile300) with C-terminus His tag and Avi tag is expressed in HEK293 cells. This protein was site-specifically labeled with Biotin by BirA ligase. 
Molecular Weight: 
The 285 amino acid protein has a predicted molecular weight of 33 kDa. The protein migrates at approximately 35-45 kDa on SDS-PAGE with DTT-reduced conditions.
Purity: 
>95% based on SDS-PAGE
Formulation: 
1xPBS buffer, pH7.4, 0.22 µm filtered
Vial Size: 
25µg, 100µg
Protein Concentration: 
25µg size is bottled at 0.2mg/mL concentration. 100 µg size is bottled at lot specific concentration.
Storage and Handling: 
Quick spin the vial after receiving. An unopened vial can be stored at 4°C for 2 weeks or at -20°C and below for six months. The protein can be further diluted to 0.1 mg/mL with 0.22 µm filtered Tris PH 7.5 buffer. This stock solution should be aliquoted and stored at ≤ -70°C to minimize the freeze/thaw cycles. Carrier proteins such as FBS and BSA need to be added if further dilution is needed.
