IGF-I/IGF-1 Protein, Mouse (His)

IGF-I/IGF-1 Protein, Mouse (His) is a mitogenic cytokine, binds to IGF type 1 receptor, and modulates growth in many tissues, such as nervous tissue, lymphoid tissue, reproductive tissue, smooth muscle, endothelium, and bone. IGF1 also mediates neuroprotective mechanism.

Insulin-like growth factor (IGF) system has been shown to modulate growth in many tissues, such as nervous tissue, lymphoid tissue, reproductive tissue, smooth muscle, endothelium, and bone. Insulin-like Growth factor-1 (IGF-I) is produced by osteoblasts, and its mitogenic effects are mediated by their binding to the IGF plasma membrane receptors. The IGF type 1 receptor binding to both IGF-I and IGF-II, is thought to be the predominate receptor involved in mediating the effects of these growth factors in most cell types, including osteoblasts^[1]. Insulin-like growth factor-1 (IGF-1) is a neurotrophic factor capable of mediating neuroprotective and neuroplasticity mechanisms. Targeted overexpression of IGF-1 enhances the generation of hippocampal newborn neurons in brain-injured mice^[2].

11-13 kDa

Greater than 95% as determined by reducing SDS-PAGE.

Lyophilized powder.

Lyophilized from a 0.2 μm filtered solution of 20 mM NaAc, pH 4.5.

<1 EU/μg, determined by LAL method.

It is not recommended to reconstitute to a concentration less than 100 μg/mL in ddH₂O. For long term storage it is recommended to add a carrier protein (0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose).

Stored at -20°C for 2 years. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer (with carrier protein). It is recommended to freeze aliquots at -20°C or -80°C for extended storage.

Room temperature in continental US; may vary elsewhere.
