How to dilute and store IGF1 Des-1?
- Aug 06, 2021 -

IGF1 Des-1 (Insulin-like Growth Factor-1, IGF 1) is an important member of insulin-like growth factor and is highly homologous to the insulin. Other members of this system also include IGF II and 1GF-1 receptor (IGFIR) , IGF Ⅱ receptor (IGFIIR) and 4 kinds of insulin growth factor binding protein (IGF

BP-1, -2, -3, -4). Insulin-like growth factor-1 (IGF-1) is a single-chain basic polypeptide molecule composed of 70 amino acids, with a molecular weight of 7649 It is derived from many cells in the body, through autocrine, paracrine and endocrine mechanisms and combined with IGF-1 receptor (IGF-1R) to play a variety of physiological functions. As a type of factor that promotes cell growth and has an insulin-like metabolic effect .IGF-1 is regulated by multiple factors such as nutritional status, hormones, genetics, etc., and plays an important role in the pathophysiological process of cardiovascular diseases, endocrine and metabolic diseases and tumors.


The human (IGF1 Des1-3) product provided is a filter-sterilized white freeze-dried powder; the freeze-dried powder is made from 50mM acetic acid containing human insulin-like growth factor-1, Des(1-3) (IGF1 Des1-3) The buffer solution is produced by further dialysis and lyophilization. We recommend adding 100mM acetic acid to prepare a working stock solution to 100ug/ml, and it can be further diluted according to the experimental requirements during subsequent experiments.


Human insulin-like growth factor-1, Des (1-3) (IGF1 Des1-3) freeze-dried powder can be stored at room temperature for 3 weeks, or stored at -18°C for long-term storage. After re-dissolution, it can be stored at 4°C Store in refrigerator for at least 2-7 days; if you want to extend the storage time, it is recommended to aliquot (load body protein such as 0.1% HSA or BSA) and store at -18°C. Please avoid repeated freezing and thawing.
