Product Description	Recombinant Human IGFBP-3 Protein is expressed from HEK293 with His tag at the C-Terminus.It contains Gly28-Lys291.
Product Background	Insulin-like growth factor binding protein-3 (IGFBP-3) is a p53 tumor suppressor-regulated protein and a major carrier for IGFs in circulation. Among six high-affinity IGFBPs, which are IGFBP-1 through 6, IGFBP-3 is the most extensively investigated IGFBP species with respect to its IGF/IGF-I receptor (IGF-IR)-independent biological actions beyond its endocrine/paracrine/autocrine role in modulating IGF action in cancer.
Product Category	Recombinant Protein / Antibody discovery

Protein	IGFBP-3
Synonyms	IBP3; IGFBP3; IGFBP-3; BP-53
Accession	AAH18962
Species	Human
Biotinylated	no
Amino Acid Range	Gly28-Lys291
Molecular Weight	The protein has a predicted MW of 29.8 kDa. Due to glycosylation, the protein migrates to 45-60 kDa based on Bis-Tris PAGE result.
Activity	Immobilized Human IGFBP-3, His Tag at 2ug/ml (100ul/well) on the plate. Dose response curve for Human IGF-II, hFc Tag with the EC50 of 0.19ug/ml determined by ELISA (QC Test). The affinity constant of 2.32 nM as determined in SPR assay (Biacore T200). See testing image for detail.
Product Tag	C-His
Expression System	HEK293
Purity	> 95% as determined by Bis-Tris PAGE
Endotoxin	Less than 1EU per ug by the LAL method.

Form	Lyophilized
Shipping	Shipped at ambient temperature.
Formulation	Lyophilized from 0.22um filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization.
Reconstitution	Centrifuge the tube before opening. Reconstituting to a concentration more than 100 ug/ml is recommended. Dissolve the lyophilized protein in distilled water.
Stability And Storage	-20 to -80°C for 12 months as supplied from date of receipt.；-80°C for 3 months after reconstitution.；Recommend to aliquot the protein into smaller quantities for optimal storage. Please minimize freeze-thaw cycles.
