无血清培养基补充剂(如胰岛素)对于常用哺乳动物细胞系的长期生长至关重要。当培养基中缺少胰岛素时,细胞形态和生长速度可能会受到干扰。重组人胰岛素已用在培养基中的间充质干细胞的成脂诱导。 它已被用作气道上皮细胞的细胞培养基中的补充剂。 它已用于细胞分化、GLUT4(4 型葡萄糖转运蛋白)易位测定的培养基中,并通过表面等离振子共振研究胰岛素与胰岛素受体的相互作用。
重组人胰岛素(rHu)在功能和结构上与天然人序列相同。由两个多肽链组成的激素,rHu 胰岛素的 A 链(21 个氨基酸)和 B 链(30 个氨基酸)通过半胱氨酸残基之间的二硫键共价连接。这种经基因工程改造的人胰岛素是全序列分子,通过重组 DNA 技术在面包酵母中生产。
产品介绍
人胰岛素是由胰岛β细胞分泌的一种多肽激素。胰岛素在许多细胞活动中发挥重要作用:如促进糖和氨基酸转运,提高合成代谢降低分解代谢,刺激细胞生长等等。胰岛素是无血清哺乳动物细胞培养基中的普遍添加物质。人胰岛素为由含有可高效表达人胰岛素基因的大肠杆菌,经发酵、分离、高度纯化、结晶和干燥制成。人胰岛素为51个氨基酸残基组成的蛋白质,分子量5808Da。

Insulin, recombinant human (rHu) is identical in function and structure to the native human sequence. A hormone consisting of two polypeptide chains, rHu Insulin′s A-chain (21 amino acids) and B-chain (30 amino acids) are covalently linked by disulfide bonds between cysteine residues. This genetically engineered human insulin is a full sequence molecule producted by recombinant DNA technology in baker′s yeast.
Product description
Human insulin is a polypeptide hormone secreted by pancreatic β-cells. Insulin plays a crucial role in numerous cellular activities, such as promoting the transport of glucose and amino acids, enhancing anabolism and reducing catabolism, stimulating cell growth, and more. Insulin is a common additive in serum-free mammalian cell culture media. Human insulin is produced through fermentation, separation, high-level purification, crystallization, and drying from Escherichia coli containing a gene that efficiently expresses human insulin. Human insulin is a protein consisting of 51 amino acid residues, with a molecular weight of 5808 Da.
Usage
Before use, dissolve it in a solution made with hydrochloric acid solution (10mM) to obtain a concentration of 1~2mg insulin per 1ml.
Purpose
It is only for R&D purposes and cannot be used for clinical treatment or consumption
Advantages and Specific
No animal-derived sources: The production process is free from exogenous viral contamination and does not utilize any animal-derived raw materials.
Stable quality: Mass production ensures stable and continuous batch production; there is no difference between product batches, and the quality remains stable.
High purity: high specific activity; host protein residuals are below the limit requirements for biological products.
Freeze-dried powder: Easy to store and transport.
Application
Serum-free medium supplements such as insulin are essential for long-term growth of commonly used mammalian cell lines. When insulin is absent from media, cell may exhibit disturbances in morphology and growth rate.
Recombinant Human Insulin has been used in the media for adipogenic induction of mesenchymal stem cells.
It has been used as a supplement in the cell culture media of airway epithelial cells.
It has been used in the culture media for differentiation of cells, GLUT4 (glucose transporter type 4) translocation assay and to study interaction of insulin with insulin receptor via surface plasmon resonance.
