產(chǎn)品規(guī)格:5μg/20μg/1mg
Synonyms | IBP-1, IGF-Binding Protein 1, AFBP, PP12, IGF-BP25, hIGFBP-1, IGFBP-1. |
Intorduction | IGFBP1 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 binds both insulin-like growth factors (IGFs) I and II and circulates in the plasma. Binding of this protein prolongs the half-life of the IGFs and alters their interaction with cell surface receptors. alternate transcriptional splice variants, encoding different isoforms, have been characterized. |
Description | Insulin-like Growth Factor Binding Protein-1 Human Recombinant is a single, glycosylated, polypeptide chain containing 218 amino acids and having a molecular mass of 28806 Dalton. IGF-Binding Protein 1 is purified by proprietary chromatographic techniques. |
Source | NSO cells. |
Physical Appearance | Sterile Filtered White lyophilized (freeze-dried) powder. |
Formulation | The protein was lyophilized with 10mM HCL. |
Solubility | It is recommended to reconstitute the lyophilized IBP-1 in sterile 18MΩ-cm H2O not less than 100μg/ml, which can then be further diluted to other aqueous solutions. |
Stability | Lyophilized IGFBP1 although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution IGF-BP1 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 95.0% as determined by(a) Analysis by RP-HPLC. (b) Analysis by SDS-PAGE. |
Biological Activity | Inhibition of IGF-I stimulated proliferation of NUC-1 cells: IC50 ~ 100 ng/ml Inhibition of serum-induced stimulation of DNA synthesis in chick embryo fibroblast primary cultures: IC50 (1% serum) ~300 ng/ml. |
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. |
