Recombinant Human Gastric Intrinsic Factor (vitamin B synthesis)

Cat. No. : GIF-5359H
Product Overview : Recombinant Human GIFproduced in baculovirus is a glycosylated, polypeptide chain containinghaving a molecular mass of 55,000 Dalton. rHu GIF is fused to ahexa-histidine at the C-terminus and purified by proprietary chromatographictechniques for removal of bound Vitamin B-12.
Description : GIF is a memberof the cobalamin transport protein family. It encodes a glycoprotein secretedby parietal cells of the gastric mucosa and is required for adequateabsorption of vitamin B12 in the terminal ileum.
Source : Sf9 Insect Cells
Species : Human
Form : The protein solution (0.7 mg/ml)contains 20 mM HEPES pH8, 100 mM NaCl, 20% Glycerol.
Purity : Greater than 95.0% asdetermined by: (a) Analysis by RP-HPLC. (b) Analysis by SDS-PAGE.
Endotoxin Level : Less than 0.1 ng/ug(IEU/ug) of recombinant Human GIF.
Biological Activity : Standard ELISA test(checker-board analysis of positive/negative sera panels), immunodot withanti-IF autoantibody positive patient sera. Can be used for solid ELISA andfluid phase diagnostic assays, 0.25-0.65µg/ml. Suitable for biotinylation andiodination.
Storage : GIF althoughstable at 10°C for 1 week, should be storeddesiccated below -18°C. For long termstorage it is recommended to add a carrier protein (0.1% HSA or BSA). Pleaseprevent freeze-thaw cycles.
