Growth Hormone Human Recombinant, HEK

Lyophilized powder at room temperature.

Growth Hormone Human Recombinant produced in HEK cells is a non-glycosylated monomer, having a total molecular weight of 22kDa.The GH is purified by proprietary chromatographic techniques.
Physical Appearance and Stability: Lyophilized GH although stable at room temperature for 3 weeks, should be stored desiccated below -18C. Upon reconstitution GH should be stored at 4C between 2-7 days and for future use below -18C.For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).Please prevent freeze-thaw cycles.
Formulation and Purity: The GH was lyophilized from 1mg/ml in 1xPBS. Greater than 95% as obsereved by SDS-PAGE.
Solubility: It is recommended to reconstitute the lyophilized GH in sterile 1xPBS containing 0.1% endotoxin-free recombinant HSA.
Biological Activity: The activity was determined by the dose dependent stimulation of the proliferation of rat lymphoma line Nb2-11 cells (prolactin indicator cell line), the ED50 is < 2ng/ml.
