Application

Cytochalasin B is used to inhibit sugar transport in fibroblasts [1], decrease cytoskeletal actin and myosin in rabbit neutrophils [2], and to stimulate B lymphocytes [3].
Cytochalasin B from Drechslera dematioidea has been used:
  • to block cytokinesis, to obtain binucleated cells[4]
  • as a specific glucose transporter inhibitor
  • to inhibit glucose transport by class I and III GLUTs to determine the 50% inhibitory concentration (IC50) in HCMV-infected and mock-infected cells

Biochem/physiol Actions

Cell permeable fungal toxin that disrupts contractile microfilaments by inhibiting actin polymerization. This, in turn, induces DNA fragmentation, inhibits cell division, and disrupts many cell processes. Inhibits glucose transport.
One of a group of fungal metabolites that interfere with a wide variety of cellular movements. Useful tool for characterizing some of the polymerization properties of actin, and in studies on cytokinesis. Probe for the two hexose-transport systems in rat L6 myoblasts.
Cytochalasin B can prevent cytoplasmic division without affecting nuclear division.

Other Notes

Keep container tightly closed in a dry and well-ventilated place. Containers which are opened must be carefully resealed and kept upright to prevent leakage.

Questions

1–4 of 4 Questions  
  1. 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.
