The plasma membrane (PM), consists of a lipid bilayer separating the intracellular environment from the extracellular space. Consequently, the PM plays a central role in many cell behaviors, such as cell migration, cell stretching, and signaling cascades. Additionally, PM dysfunction is an important biomarker because it is related to the cell status and is linked to many diseases.
Dojindo’s PlasMem Bright dyes overcome these limitations. PlasMem Bright dyes are designed to stain PMs for over a day. Furthermore, the PlasMem Bright dyes are more water-soluble compared with other commercially available dyes and can be diluted with culture medium. The PlasMem Bright dyes offer two different color options (green and red) and are provided as ready-to-use DMSO solutions. A working solution can be prepared easily via a single dilution step using growth medium or HBSS.

Low toxicity, No washing, and High retentivity
High retentivity on plasma membrane
HeLa cells stained with each plasma membrane staining reagent were incubated for 24 hrs and each the resulting fluorescent image was compared. PlasMem Bright series had higher retentivity on plasma membrane than other products.
