Amino Acid Sequence



E. coli


˃ 90 % by SDS-PAGE


14% SDS-PAGE separation of Human FABP-2
1. M.W. marker – 97, 66, 45, 31, 21, 14 kDa
2. reduced and boiled sample, 5μg/lane
3. non-reduced and non-boiled sample, 5μg/lane


< 1.0 EU/µg


Filtered (0.4 μm) and lyophilized from 0.5 mg/ml solution in phosphate buffered saline, pH 7.4


Add deionized water to prepare a working stock solution of approximately 0.5 mg/mL and let the lyophilized pellet dissolve completely.


Western blotting, ELISA


At ambient temperature. Upon receipt, store the product at the temperature recommended below.


Store lyophilized protein at -80°C. Lyophilized protein remains stable until the expiry date when stored at -80°C. Aliquot reconstituted protein to avoid repeated freezing/thawing cycles and store at -80°C for long term storage. Reconstituted protein can be stored at 4°C for a week.

Quality Control Test

BCA to determine quantity of the protein.
SDS PAGE to determine purity of the protein. Endotoxin level determination.
