About this Antibody

Name

Recombinant Rat IGF-1 (Recombinant Rat Insulin-like Growth Factor 1; rRtIGF-1)；重组大鼠胰岛素样生长因子1

Synonyms

IGF1; IGF-1; Somatomedin A; Somatomedin C; IBP1; IGF1A; IGFI; IGF-I; IGF-IA; IGF-IB; insulin-like growth factor 1; insulin-like growth factor 1 (somatomedin C); insulin-like growth factor I; insulin-like growth factor IA; insulin-like growth factor IB; Mechano growth factor; MGF; somatomedin-C; Somatomedin-C

Purity

>97% by SDS-PAGE and HPLC analyses.

Biological Activity

Fully biologically active when compared to standard. The ED50 as determined by a cell proliferation assay using serum free human MCF-7 cells is less than 2ng/ml, corresponding to a specific activity of >5.0×10⁵IU/mg.

Physical Appearance

Sterile Filtered White lyophilized (freeze-dried) powder.

Formulation

Lyophilized from a 0.2μm filtered concentrated solution in PBS, pH7.4.

Endotoxin

Less than 1EU/μg of rRtIGF-1 as determined by LAL method.

Reconstitution

We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Reconstitute in sterile distilled water or aqueous buffer containing 0.1% BSA to a concentration of 0.1-1.0mg/ml. Stock solutions should be apportioned into working aliquots and stored at ≤-20℃. Further dilutions should be made in appropriate buffered solutions.

Background

The insulin-like growth factors (IGFs) belonged to the insulin gene family, are mitogenic polypeptide growth factors that stimulate the proliferation and survival of various cell types including muscle, bone, and cartilage tissue in vitro. The IGFs are similar by structure and function to insulin, but have a much higher growth-promoting activity than insulin. IGF-1 is produced primarily by the liver as an endocrine hormone as well as in target tissues in a paracrine/autocrine fashion. The production of IGF-1 is stimulated by growth hormone (GH) and can be retarded by undernutrition, growth hormone insensitivity, lack of growth hormone receptors, or failures of the downstream signaling pathway post GH receptor including SHP2 and STAT5B. Recombinant human IGF-1 are globular proteins containing 70 amino acids and 3 intra-molecular disulfide bonds. Mature rat IGF-1 shares 96%a.a. sequence identity with human IGF-1 and exhibits cross-species activity.
