• Sequence Length: 153

• Domain: Insulin
• Host Note: Optimized DNA sequence encoding Human Insulin Growth Factor -1mature chain was expressed in Escherichia Coli.
• Endotoxin: Endotoxin content was assayed using a LAL gel clot method.; Endotoxin level was found to be less than 0.1 ng/ug (1EU/ug).
• Reconstitution: A quick spin of the vial followed by reconstitution in distilled water to a concentration not less than 0.1 mg/mL. This solution can then be diluted into other buffers.
• Molecular Weight Note: Native Human Insulin Growth Factor-1 is generated by the proteolytic removal of the signal peptide and propeptide, the molecule has a calculated molecular mass of approximately 8 kDa.; Recombinant Human IGF-1 is a disulfide-linked monomeric protein consisting of 71 amino acid residue subunits. IGF-1 migrates as an approximately 8 kDa protein under non-reducing and reducing conditions in SDS-PAGE.
• Preparation and Storage: The lyophilized protein is stable for at least 2 years from date of receipt at -20 degree C.; Upon reconstitution, this cytokine can be stored in working aliquots at 2 degree - 8 degree C for one month, or at -20 degree C for six months, with a carrier protein without detectable loss of activity. ; ; Avoid repeated freeze/thaw cycles.

Related Product Information for IGF-I recombinant protein

Insulin-like growth factor I, also known as somatomedin C, is the dominant effector of growth hormone and is structurally homologous to proinsulin. Human IGF-I is synthesized as two precursor isoforms with N- and alternate C- terminal propeptides (1). These isoforms are differentially expressed by various tissues (1). The 7.6 kDa mature IGF-I is identical between isoforms and is generated by proteolytic removal of the N- and C- terminal regions. Mature human IGF-I shares 94% and 96% aa sequence identity with mouse and rat IGF-I, respectively (2), and exhibits cross-species activity. It shares 64% aa sequence identity with mature human IGF-II. Circulating IGF-I is produced by hepatocytes, while local IGF-I is produced by many other tissues in which it has paracrine effects.
