| IGF is a well-characterized basic peptide believed to be secreted by the liver and to circulate in the blood. It has growth-regulating, insulin-like, and mitogenic activities. This growth factor has a major, but not absolute, dependence on Somatotropin. It is believed to be mainly active in adults in contrast to Insulin like Growth Factor 2, which is a major fetal growth factor. | | | Catalog # | I7661-09P | | Endotoxin | <0.01ng/ug or <0.1EU/ug as per LAL | | Biological Activity | Recombianant Interferon gamma is fully biologically active when compared to standard.
