Overview

  • Product name(S)-(-)-Blebbistatin
  • Description
    Selective myosin II ATPase activity inhibitor
  • Biological descriptionSelective myosin II ATPase activity inhibitor (IC50 = 8.5 μM). Active enantiomer of blebbistatin (ab120425). Inhibits actin-activated MgATPase activity and in vitro motility of class II myosins. Also inhibits contraction of the cytokinetic ring. Blocks cell blebbing and disrupts directed cell migration and cytokinesis.
  • Purity> 99%

    (S)-(-)-Blebbistatin images

    • ab32084 staining paxillin in MEF1 cells treated with (S)-(-)-Blebbistatin (ab120491), by ICC/IF. Decreased membrane expression of paxillin correlates with increased concentration of (S)-(-)-Blebbistatin , as described in literature.
      The cells were incubated at 37°C for 2h in media containing different concentrations of ab120491 ( (S)-(-)-Blebbistatin ) in DMSO, fixed with 4% formaldehyde for 10 minutes at room temperature and blocked with PBS containing 10% goat serum, 0.3 M glycine, 1% BSA and 0.1% tween for 2h at room temperature. Staining of the treated cells with ab32084 (1/100 dilution) was performed overnight at 4°C in PBS containing 1% BSA and 0.1% tween. A DyLight 488 goat anti-rabbit polyclonal antibody (ab96899) at 1/250 dilution was used as the secondary antibody. Nuclei were counterstained with DAPI and are shown in blue.
