Description
Accession
P49745
Source
Optimized DNA sequence encoding Rat THPO mature chain was expressed in CHO. Recombinant Rat Thrombopoietin encodes amino acid residues 22-326.
Molecular weight
Recombinant THPO migrates as an approximately 19 kDa protein due to glycosylation under reducing conditions in SDS-PAGE.
Purity
>95%, as determined by SDS-PAGE and HPLC
Biological Activity
Determined by its ability to stimulate the proliferation of human MO7e cells. The expected ED50 is ≤ 0.2 ng/ml, corresponding to a specific activity of ≥ 5 x 106 units/mg.
Endotoxin
Endotoxin content was assayed using a LAL gel clot method. Endotoxin level was found to be less than 0.1 ng/µg(1EU/µg).
Presentation
THPO was Lyophilized from PBS, pH 7.2.

Reconstitution
A quick spin of the vial followed by reconstitution in distilled water to a concentration not less than 0.1 mg/mL. This solution can then be diluted into other buffers.
Storage
The lyophilized protein is stable for at least 2 years from date of receipt at -20° C. Upon reconstitution, this product can be stored in working aliquots at 2° - 8° C for one month, or at -20° C for six months, with a carrier protein without detectable loss of activity. Avoid repeated freeze/thaw cycles.
