Vybrant Lipid Raft Labeling Kits are designed to provide convenient, reliable and extremely bright fluorescent labeling of lipid rafts in live cells. Kits include cholera toxin subunit B (CT-B) labeled with either the green-fluorescent Alexa Fluor 488, the orange-fluorescent Alexa Fluor 555 or the red-fluorescent Alexa Fluor 594 dye, as well as an antibody that specifically recognizes CT-B. A 10X solution of phosphate-buffered saline (10X PBS), pH 7.2, and detailed instructions are also included in the kits.
