IGF2 Human

Insulin-Like Growth Factor-2 Human Recombinant

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 7505 Dalton.
IGF-II is purified by proprietary chromatographic techniques.

Accession

P01344

Amino acid sequence

AYRPSETLCG GELVDTLQFV CGDRGFYFSR PASRVSRRSR GIVEECCFRS CDLALLETYC ATPAKSE.

Biological Activity

The ED50, calculated by the dose-dependent induction of MCF-7 cell proliferation was found to be 0.85ng/ml corresponding to a Specific Activity of 1,176,470IU/mg.

Formulation

The protein was lyophilized with no additives.

Physical Appearance

Sterile Filtered White lyophilized (freeze-dried) powder.

Purity

Greater than 97.0% as determined by:
(a) Analysis by RP-HPLC.
(b) Analysis by SDS-PAGE.

Solubility

It is recommended to reconstitute the lyophilized IGF2 in sterile 18MΩ-cm H2O at a concentration of 100ug/ml, which can then be further diluted to other aqueous solutions.

Source

Escherichia Coli.

Stability

Lyophilized IGF-2 although stable at room temperature for 3 weeks, should be stored desiccated below -18oC. Upon reconstitution IGFII should be stored at 4oC between 2-7 days and for future use below -18oC.
For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).
Please prevent freeze-thaw cycles.

Synonyms

Somatomedin-A, IGF2, INSIGF, pp9974, C11orf43, FLJ22066, FLJ44734.
