Predicted Molecular Weight
The 190 amino acid recombinant protein has a predicted molecular mass of approximately 22 kD. The protein migrates as above 25 kD in SDS-PAGE in DTT-reducing condition and above 22 kD in non-reducing condition. The N-terminal amino acid is Gln.
Expression System
CHO Cells
Source Species
Hamster-Chinese
Purification
Greater than 95% by SDS-PAGE
Bio-Activity
Measured by its ability to bind all-trans retinoic acid. The binding of retinoic acid results in the quenching of tryptophan fluorescence in RBP4. The ED50 of RBP4 to all-trans rentinoic acid is >0.5 µM.
Endotoxin
Less than 0.1 EU/µg protein (determined by LAL method).
Presentation
0.22 µm filtered protein solution in PBS
Storage
Store unopened at 2°C to 8°C for up to 3 months, at -20°C for up to 6 months, or at -70°C for up to 1 year. Store diluted at 2°C to 8°C for up to 1 month, or at -20°to -70°C for up to 3 months. Avoid freeze/thaw cycles. For maximum results, quick spin vial prior to opening.
Restrictions
For research use only. Intended for use by laboratory professionals.
