製品名(±)-Blebbistatin, inhibitor of myosin II
製品の詳細Potent, selective, inhibitor of myosin II
生理活性の詳細Cell-permeable, reversible inhibitor of non-muscle myosin II. Shows high affinity and selectivity for vertebrate and invertebrate Myosin II (IC50 values 0.5-5 μM). 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.
保存方法Store at +4°C. Store under desiccating conditions. The product can be stored for up to 12 months.
溶解性Soluble in DMSO to 100 mM
Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20°C. Generally, these will be useable for up to one month. Before use, and prior to opening the vial we recommend that you allow your product to equilibrate to room temperature for at least 1 hour.
Refer to SDS for more information.

ab32084 staining paxillin in MEF1 cells treated with (+/-)-blebbistatin (ab120425), by ICC/IF. Decreased membrane expression of paxillin correlates with increased concentration of (+/-)-blebbistatin, as described in literature.
The cells were incubated at 37°C for 1h in media containing different concentrations of ab120425 ((+/-)-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.
