Introduction	IGFBP5 is a member of the insulin-like growth factor binding protein (IGFBP) family and encodes a protein with an IGFBP domain and a thyroglobulin type-I domain. The protein forms a ternary complex with insulin-like growth factor acid-labile subunit (IGFALS) and either insulin-like growth factor (IGF) I or II. In this form, it circulates in the plasma, prolonging the half-life of IGFs and altering their interaction with cell surface receptors. Alternate transcriptional splice variants, encoding different isoforms, have been characterized.
Description	IGFBP5 Human Recombinant produced in E.Coli is a single, non-glycosylated, homodimeric polypeptide chain containing 252 amino acids and having a molecular mass of 28.6 kDa. IGFBP5 is purified by proprietary chromatographic techniques.
Source	Escherichia Coli.
Physical Appearance	Sterile Filtered White lyophilized (freeze-dried) powder.
Formulation	IBP-5 was lyophilized from a concentrated (1mg/ml) solution containing 10mM sodium Citrate pH-3 .
Purity	Greater than 98.0% as determined by: (a) Analysis by RP-HPLC. (b) Analysis by SDS-PAGE.
Usage	ProSpec's products are furnished for LABORATORY RESEARCH USE ONLY. The product may not be used as drugs, agricultural or pesticidal products, food additives or household chemicals.

Biological Activity	The ED₅₀, calculated by its ability to inhibit IGF-II induced proliferation of MCF-7. The expected ED50 for this effect is 0.4 g/ml, corresponding to a specific activity of 2500 IU/mg in the presence of 15 ng/ml of rHuIGF-II.
Storage	Lyophilized IBP5 although stable at room temperature for 3 weeks, should be stored desiccated below -18C. Upon reconstitution IGFBP 5 should be stored at 4C between 2-7 days and for future use below -18C. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA). Please prevent freeze-thaw cycles.
