Target Name: 
Human CD200 Protein, OX-2 Membrane Glycoprotein; CD200; MOX1; MOX2
Source:
Recombinant Human CD200 is produced in CHO cells, and the target gene encoding Gln31-Gly232 is expressed with a 8His tag at the C-terminus. 
Molecular Weight:
The protein has a predicted molecular weight of 24kDa and migrates at approximately 40-50kDa on SDS-PAGE with DTT-reduced condition.
Purity:
>95% based on SDS-PAGE under reducing condition
Formulation:
1xPBS buffer, pH7.4, 0.22 µm filtered
Endotoxin Level:
Not Tested
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. 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 PBS 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.
