General description
Insulin is a two-chain polypeptide hormone produced by the β-cells of pancreatic islets. Its molecular weight is ~5800 Da. The α and β chains are joined by two interchain disulfide bonds. The α chain contains an intrachain disulfide bond.
Application
Insulin solution human has been used as a supplement in Dulbecco′s modified eagle′s medium (DMEM) to culture epithelial cell line and human endometrial cell line, minimum essential medium eagle to culture human breast adenocarcinoma cell line and medium 199 to culture normal ovarian cell line.
Insulin solution human is recommended for use in cell culture applications at 0.5 to 1mL per liter of medium.
Insulin solution human has been used for insulin tolerance test in mice and rats.[1] It has also been used for adipogenic differentiation of human embryonic stem cells (hESCs)-derived outgrowth cultures and hMSCs (human mesenchymal stromal cells).[2]

Biochem/physiol Actions
Insulin plays a role in various cellular processes, such as promoting cell growth, regulating the cell cycle, and facilitating glucose uptake. It is commonly used as a protein supplement in serum-free mammalian cell culture media to help promote the optimal growth and maintenance of mammalian cells.

OCT4 (Octamer-binding transcription factor 4) is essential for embryonic stem cell self-renewal. Here we show that OCT4 increases the aggressiveness of high-grade serous ovarian cancer (HG-SOC) by inactivating the Retinoblastoma tumor suppressor pathway and enhancing mitotic stability in cancer cells.

Can I aliquot the insulin and freeze it? Is it still functional after thawing?
1 answer-
This product is recommended to be stored at 2-8°C. For research applications, freezing insulin solution is a common practice. However, solutions available on the commercial market for therapeutic use are not frozen to maintain maximum activity. No stability studies have been performed on the shelf life of frozen insulin solutions.
