IGF-I, human, recombinant
The IGFs are mitogenic polypeptide growth factors that stimulate the proliferation and survival of various cell types including muscle, bone, and cartilage tissue in vitro. IGFs are predominantly produced by the liver, although a variety of tissues produce the IGFs at distinctive times. The IGFs belong to the Insulin gene family, which also contains insulin and relaxin. The IGFs are similar by structure and function to insulin, but have a much higher growth-promoting activity than insulin. IGF-II expression is influenced by placenta lactogen, while IGF-I expression is regulated by growth hormone. Both IGF-I and IGF-II signal through the tyrosine kinase type I receptor (IGF-IR), but, IGF-II can also signal through the IGF-II/Mannose-6-phosphate receptor. Mature IGFs are generated by proteolytic processing of inactive precursor proteins, which contain N-terminal and C-terminal propeptide regions. Recombinant human IGF-I and IGF-II are globular proteins containing 70 and 67 amino acids, respectively, and 3 intra-molecular disulfide bonds.

Protein A (recombinant), 5 mg
Recombinant protein A binds immunoglobulins (primarily IgG) at the Fc region with high affinity. In some cases, IgM and IgA will also bind. This property provides a rapid, simple and economical method for purification and analysis of a broad-spectrum of antibodies. Fractionation of IgG subclasses can also be performed using recombinant protein A. Because of its high affinity for immunoglobulins of many species and its low level of non-specific binding, recombinant protein A is useful for the study of cell surface antigens and receptors, and for detecting antibody-secreting cells. Recombinant protein A is produced in an E. coli strain which contains the gene for mature protein A from Staphylococcus aureus Cowan I strain.
