Description
| Product Name: | Human IGFBP3 Recombinant Protein |
| Product Code: | RPPB0431 |
| Size: | 25µg |
| Species: | Human |
| Target: | IGFBP3 |
| Synonyms: | GH-dependant binding protein, IBP3, BP-53, IGFBP-3. |
| Source: | Escherichia Coli |
| Physical Appearance: | Sterile Filtered White lyophilized (freeze-dried) powder. |
| Formulation: | Lyophilized from a 0.2�m filtered concentrated (0.5mg/ml) solution in PBS, pH 7.4. |
| Solubility: | It is recommended to reconstitute the lyophilized�IGFBP3 in sterile 20mM AcOH (acetic Acid) not less than 100�g/ml, which can then be further diluted to other aqueous solutions. |
| Stability: | Lyophilized IBP3 although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution IGF-BP 3 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. |
| Purity: | Greater than 97.0% as determined by:(a) Analysis by RP-HPLC.(b) Analysis by SDS-PAGE. |

| Biological Activity: | The ED50, calculated by by its ability to inhibit IGF-II induced proliferation of MCF-7 is�< 0.2 �g/ml in the presence of 15 ng/ml of Human IGF-II, corresponding to a specific activity of 5,000,000units/mg. |
IGFBP3 is a member of the IGFBP family and encodes a protein with an IGFBP domain and a thyroglobulin type-I domain. The protein forms a ternary complex with IGFALS and either 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.
IGFBP3 Human Recombinant produced in E.Coli is a homodimeric, non-glycosylated, polypeptide chain containing 2x264 amino acids and having a molecular mass of 28806 Dalton. IGFBP-3 is purified by proprietary chromatographic techniques.
| UniProt Protein Function: | IGFBP3: IGF-binding proteins prolong the half-life of the IGFs and have been shown to either inhibit or stimulate the growth promoting effects of the IGFs on cell culture. They alter the interaction of IGFs with their cell surface receptors. Also exhibits IGF-independent antiproliferative and apoptotic effects mediated by its receptor TMEM219/IGFBP-3R. |

| NCBI Summary: | This gene 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. [provided by RefSeq, Jul 2008] |
