一般描述

离子霉素(Ionomycin)是一种由密团链霉菌(Streptomyces conglobatus)产生的钙离子载体，可穿过细胞膜运输钙离子。常作为一种高效工具用以研究钙离子介导信号转导及钙离子在各种生物过程中的作用，包括细胞激活、分泌、增殖和凋亡。

离子霉素在细胞生物学研究中常用于快速可控地提高胞内钙离子浓度。进而可研究钙离子信号转导通路的下游效应，例如酶激活、激素释放和基因表达变化。离子霉素也用于研究钙离子在某些细胞过程中的作用，包括细胞死亡、免疫细胞激活和肌肉收缩。具体上，比如离子霉素可用于诱导癌细胞凋亡、研究T细胞激活、探索肌肉收缩中的钙作用。

应用

离子霉素用途：
  • 研究钙离子介导信号转导及钙离子在各种生物过程中的作用
  • 研究细胞内钙浓度、钙依赖性酶和钙内流引起的细胞反应
  • 在细胞生物学研究中快速可控地提高胞内钙离子浓度
  • 联合荧光钙离子指示剂或蛋白激酶激活剂等物质研究某些细胞机制和信号通路
离子霉素已用于：
  • 诱发中枢性脱髓鞘
  • 抑制牛肾上腺TREK-1通道
  • 调节人成熟B细胞的细胞分裂

生化/生理作用

离子霉素是一种离子渗透型抗生素，可与Pb2+和Ca2+结合，用作两种阳离子的有效移动载体。

作用机制：促进钙离子(Ca2+)跨生物膜运输

抗菌谱：对革兰氏阳性菌有抗菌活性。
离子霉素是一种离子渗透型抗生素，可与Pb2+和Ca2+结合，可用作两种阳离子的有效动态载体。离子霉素作为C2+的动态载体比A23187更有效。它是非荧光的。它用于研究跨生物膜的Ca2+转运，并诱导胚胎皮质神经元的凋亡性变性。

特点和优势

  • 成品溶液，无需制备
  • 钙离子信号转导及钙在各种生物过程中作用的高效研究工具
  • 快速可控地调节胞内钙浓度
  • 功能多样，广泛用于细胞生物学研究

  1. How does the storage temperature relate to shipping conditions?

    The storage conditions that a Sigma-Aldrich catalog and label recommend for products are deliberately conservative. For many products, long-term storage at low temperatures will increase the time during which they are expected to remain in specification and therefore are labeled accordingly. Where short-term storage, shipping time frame, or exposure to conditions other than those recommended for long-term storage will not affect product quality, Sigma-Aldrich will ship at ambient temperature. The products sensitive to short-term exposure to conditions other than their recommended long-term storage are shipped on wet or dry ice. Ambient temperature shipping helps to control shipping costs for our customers. At any time, our customers can request wet- or dry-ice shipment, but the special handling is at customer expense if our product history indicates that the product is stable for regular shipment. See Shipping and Storage for more information.

  2. Which document(s) contains shelf-life or expiration date information for a given product?

    If available for a given product, the recommended re-test date or the expiration date can be found on the Certificate of Analysis.

  3. How do I get lot-specific information or a Certificate of Analysis?

    The lot specific COA document can be found by entering the lot number above under the "Documents" section.

  4. How do I find price and availability?

    There are several ways to find pricing and availability for our products. Once you log onto our website, you will find the price and availability displayed on the product detail page. You can contact any of our Customer Sales and Service offices to receive a quote.  USA customers:  1-800-325-3010 or view local office numbers.

  5. What is the Department of Transportation shipping information for this product?

    Transportation information can be found in Section 14 of the product's (M)SDS.To access the shipping information for this material, use the link on the product detail page for the product. 

  6. Is Product No. I3909 (Ionomycin calcium salt solution) hygroscopic?

    Yes, this product is hygroscopic.  It is packaged under an inert gas.  It is recommended to store I3909 under an inert gas and at -20°C protected from light.

  7. What is the concentration of the Ionomycin calcium salt solution, Product No. I3909?

    It is a 1mM solution or ~ 0.75mg/mL in DMSO.

  8. Has Ionomycin calcium salt solution, Product No. I3909, been tested for use in Cell Culture applications?

    Sigma Aldrich has not tested this material for use in cell culture.  However, several references for use of ionomycin in cell culture applications can be found in the product information sheet (under Documents, above).
