Amino acid sequence
The sequence of the first five N-terminal amino acids was determined and was found to be Thr-Leu-Cys-Gly-Ala.
The ED50, calculated by the dose-dependant proliferation of murine BALB\C 3T3 cells (measured by 3H-thymidine uptake) is < 1ng/ml, corresponding to a specific activity of 1MIU/mg.For most in-vitro applications, IGF-I des1-3 exerts its biological activity in the concentration range of 0.2-20 ng/ml corresponding to a specific activity of 50,000IU-5MIU/mg.
IGF-I Des(1-3) Human Recombinant produced in E.Coli is a single, non-glycosylated, polypeptide chain containing 67 amino acids (aa 4-70) and having a molecular mass of 7372 Dalton.
IGF-1 Des1-3 is purified by proprietary chromatographic techniques.
The protein was lyophilized after extensive dialysis against 50mM acetic acid buffer.
Sterile Filtered White lyophilized (freeze-dried) powder.
Greater than 95.0% as determined by(a) Analysis by RP-HPLC.
(b) Analysis by SDS-PAGE.
It is recommended to reconstitute the lyophilized IGF-I Des(1-3) in 100mM Acetic acid not less than 100¦Ìg/ml, which can then be further diluted to other aqueous solutions.
Lyophilized IGF-I des(1-3) although stable at room temperature for 3 weeks, should be stored desiccated below -18¡ãC. Upon reconstitution IGF1 des-1-3 should be stored at 4¡ãC between 2-7 days and for future use below -18¡ãC.
For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).
Please prevent freeze-thaw cycles.
