IGFBP-4 Human Recombinant amino acids Asp22- Glu258, produced in HEK293 cells and fused with a polyhistidine tag at the C-terminus. IGFBP4 predicted Mw is 27kDa and on SDS-PAGE appears as a 32kDa band under denaturing conditions.
- Expression host: HEK293 cells.
- Purity: Greater than 95.0% as determined by SDS-PAGE.
- Biological activity: The ED50 range is 0.01-0.09ug/ml as measured by its ability to inhibit the biological activity of IGFII (20ng/ml) on MCF7 human breast adenocarcinoma cells.
- Formulation: IGFBP 4 was lyophilized after extensive dialysis against PBS.
- Appearance: Sterile Filtered White lyophilized (freeze-dried) powder.
- Stability: Lyophilized IGFBP4 although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution IGFBP-4 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 ...
