- Abstract:
- The coding part of the cDNA of cardiac fatty acid-binding protein (cFABP) from bovine heart was cloned into the vector pKK233-2. After induction with isopropyl-beta-D-thiogalactopyranoside cFABP was found in a soluble form in the cytosol of plasmid transformed E. coli amounting up to 5.7% of the soluble protein. cFABP was detected after SDS-polyacrylamide gelelectrophoresis and/or isoelectric focusing and Western blot by immuno-staining and was determined quantitatively by a solid phase enzyme-linked immuno sorbent assay. The cFABP produced by bacteria binds oleic acid with high affinity as shown by comigration of protein and ligand in both gelfiltration and isoelectric focusing. cFABP was purified from bacterial lysates to near homogeneity and resolved into four isoproteins.
