Recombinant Human IGFBP 4 General Information
Alternate Names
Insulin-like growth factor-binding protein 4, IBP-4, IGF-binding protein 4, IGFBP-4, IGFBP4, IBP4, BP-4, HT29-IGFBP.
Curated Database and Bioinformatic Data
UniProt ID(s)P22692
General Description of Recombinant Human IGFBP 4.
Human IGFBP-4 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 using an optimized multi-step FPLC method for maximum separation from contaminants.

Human IGFBP 4 Bioactive Protein Product Attributes

Product Type: Bioactive Protein
Recombinant IGFBP 4 based upon sequence from Human
Host: QP10684 protein expressed in HEK 293.
Available Tags: His
Protein Construction: A cDNA sequence encoding the sequence of IGFBP 4 was constructred and used to recombinantly synthesize the protein.
Recommended Applications: Bioactive
Application Notes
Recommended Reconstitution Instructions: 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.
Bioactivity Data: 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.

Purity: Greater than 95.0% as determined by SDS-PAGE.
Endotoxin Levels:
Buffer: IGFBP 4 was lyophilized after extensive dialysis against PBS.
Storage Conditions: 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.
Physical Appearance: Sterile Filtered White lyophilized (freeze-dried) powder.
