Insulin-like growth factor II (IGF-II) is an important foetal growth hormone.IGF-II is made by theca cells during gestation. IGF-II binds the sink IGF-II receptor (IGF2R) which results in IGF-II degradation.IGF-II also engages the IGF-I receptor (IGF1R) to arbitrate embryonic growth.
IGF2 Mouse Recombinant produced in E.Coli is a single, non-glycosylated, monomeric polypeptide chain containing 67 amino acids and having a total molecular mass of 7.4kDa.
The IGF2 is purified by proprietary chromatographic techniques.
Lyophilized from a sterile (0.2µ) filtered solution containing 0.1 % trifluoroacetic acid (TFA).
It is recommended to reconstitute the lyophilized IGF2 in sterile water at a concentration of 0.1 mg/ml, which can then be further diluted to other aqueous solutions.
Lyophilized IGF2 although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution IGF2 Human should be stored at 4°C between 2-7 days and for future use below -18°C. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA). Please prevent freeze-thaw cycles.
