产品描述:
Insulin-like Growth Factor-1 (IGF-1) is the principal hormonal mediator of statural growth. Under normal circumstances, growth hormone (GH) binds to its receptor in the liver, and other tissues, and stimulates the synthesis/secretion of IGF-1. In target tissues, the Type 1 IGF receptor, which is homologous to the insulin receptor, is activated by IGF-1, leading to intracellular signaling which stimulates multiple processes leading to statural growth. The metabolic actions of IGF-1 are in part directed at stimulating the uptake of glucose, fatty acids, and amino acids so that metabolism supports growing tissues. The LR3 is a long-term analog of human IGF-1, specifically designed and manufactured for mammalian cell culture to support large-scale manufacturing of recombinant biopharmaceuticals.


表达系统 :
Escherichia coli


溶解方法:
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 0.1-1.0 mg/mL. Stock solutions should be apportioned into working aliquots and stored at < -20°C. Further dilutions should be made in appropriate buffered solutions.


产品组成:
Lyophilized from a 0.2 μm filtered concentrated solution in 20 mM PB, pH 7.2.


存储条件:
This lyophilized preparation is stable at 2-8°C, but should be kept at -20°C for long term storage, preferably desiccated. Upon reconstitution, the preparation is stable for up to one week at 2-8°C. For maximal stability, apportion the reconstituted preparation into working aliquots and store at -20°C to -70°C. Avoid repeated freeze/thaw cycles.


分子量:
Approximately 9.1 kDa, a single non-glycosylated polypeptide chain containing 83 amino acids.


内毒素:
Less than 5 EU/100μg of LR3IGF-1 as determined by LAL method.


产品用途:
This material is offered by Cyagen Biosciences for research, laboratory or further evaluation purposes. FOR RESEARCH USE ONLY. NOT INTENDED FOR ANY ANIMAL OR HUMAN THERAP EUTIC OR DIAGNOSTIC USE.


生物学活性:
The ED50 determined by the stimulation of protein synthesis using rat L6 myoblasts is less than 10 ng/mL, corresponding to a specific activity of > 1.0 × 105 IU/mg.


产品形态:
Sterile filtered white lyophilized (freeze-dried) powder.
