Description

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. IGFBP4 is purified by proprietary chromatographic techniques.

Storage & Handling

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 add a carrier protein (0.1% HSA or BSA). Please prevent freeze-thaw cycles.

Form

Sterile Filtered White lyophilized (freeze-dried) powder.

Formulation

IGFBP 4 was lyophilized after extensive dialysis against PBS.

Purity

Greater than 95.0% as determined by SDS-PAGE.

Predicted MW

27.934kDa

Reconstitution

It is recommended to reconstitute the lyophilized IGFBP4 in sterile 18M-cm H2O not less than 100µg/ml, which can then be further diluted to other aqueous solutions.

Biological Activity

The ED50 range is 0.01-0.09µg/ml as measured by its ability to inhibit the biological activity of IGFII (20ng/ml) on MCF7 human breast adenocarcinoma cells.

Reconstitution

It is recommended to reconstitute the lyophilized IGFBP4 in sterile 18M-cm H2O not less than 100µg/ml, which can then be further diluted to other aqueous solutions.
