应用

源于Drechslera dematioidea的细胞松弛素B已被用于:
  • 阻断胞质分裂,获得双核细胞[1]
  • 作为特异性葡萄糖转运体抑制剂[2]
  • 抑制I、III类GLUT对葡萄糖的转运,测定HCMV感染细胞和模拟感染细胞的50%抑制浓度(IC50)[3]

细胞松弛素B用于抑制成纤维细胞[4]中的糖转运,减少兔中性粒细胞[5]中的细胞骨架肌动蛋白和肌球蛋白,并刺激B淋巴细胞[6]

生化/生理作用

一种干扰多种细胞运动的真菌代谢物。用于表征肌动蛋白某些聚合特性以及研究胞质分裂的有用工具。大鼠L6成肌细胞中两个己糖转运系统的探针。
一种通过抑制肌动蛋白聚合来破坏收缩微丝的细胞渗透性真菌毒素。反过来,这会诱导DNA片段化,抑制细胞分裂并破坏许多细胞过程。抑制葡萄糖转运。
细胞松弛素B可以阻止胞质分裂而不影响核分裂。[7]

Questions

1–4 of 4 Questions  
  1. What is the Department of Transportation shipping information for this product?

    1 answer
    1. 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.

  2. Is Product C2743, Cytochalasin B, cell culture grade?

    1 answer
    1. The product has been sterile filtered, but it has not been cell culture tested by Sigma.

      Helpful?

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

    1 answer
    1. 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.

  4. I have a solution of Product C2743, Cytochalasin B, in DMSO. Is the DMSO toxic to cultured cells?

    1 answer
    1. At a low enough concentration, the DMSO should not hurt the cells. The final concentration of DMSO in the aqueous working medium typically should not exceed 0.1% because higher DMSO concentrations can adversely affect many cultured cells. Dilute the product in the appropriate aqueous medium to provide a physiologically acceptable final concentration.
