IGF-2 is a member of the INS family of polypeptide growth factors that is involved in development and growth. It is an imprinted gene and is expressed only from the paternally inherited allele. It is a candidate gene for eating disorders. There is a read-through, INS-IGF2, which aligns to this gene at the 3' region and to the upstream INS gene at the 5' region. Two alternatively spliced transcript variants encoding the same protein have been found for this gene.
Insulin-Like Growth Factor- II Human Recombinant produced in E.Coli is a single, non-glycosylated, polypeptide chain containing 67 amino acids and having a molecular mass of 7.5k Dalton.
IGF-II is purified by proprietary chromatographic techniques.
The protein was lyophilized from a sterile filtered solution containing 0.1 % trifluoroacetic acid (TFA).
For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).
Please prevent freeze-thaw cycles.
Greater than 95.0% as determined by SDS-PAGE.
Amino acid sequence
The activity is determined by the dose dependent proliferation of FDC-P1 cells and is typically 1.4 ng/mL corresponding to a specific activity of 7.1x105units/mg.
