外观(Physical Appearance)

Sterile Filtered White lyophilized (freeze-dried) powder.

纯度(Purity)

> 97 % by SDS-PAGE and HPLC analyses.

生物活性(Biological Activity)

Fully biologically active when compared to standard. The ED50 as determined by its ability to inhibit IGF-II induced proliferation of MCF-7 cells is less than 0.1 μg/mL, corresponding to a specific activity of > 1.0 × 104 IU/mg in the presence of 14 ng/ml of rHuIGF-II.

内毒素(Endotoxin)

< 0.1 EU per 1μg of the protein by the LAL method.

制剂(Formulation)

Lyophilized from a 0.2 μm filtered concentrated solution in 20mM Tris-HCl, pH 8.0, 150mM NaCl.

复溶(Reconstitution)

We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Reconstitute in sterile distilled water or aqueous buffer containing 0.1% BSA to a concentration of 0.1-1.0 mg/mL. Stock solutions should be apportioned into working aliquots and stored at ≤ -20 °C. Further dilutions should be made in appropriate buffered solutions.

 

储存条件
