Invitrogen™ LIVE BacLight™ Bacterial Gram Stain Kit, for microscopy & quantitative assays

The LIVE BacLight™ Bacterial Gram Stain Kit provides a novel one-step fluorescence assay for the determination of gram sign in living bacteria. When gram negative and gram-positive bacterial are simultaneously stained with the membrane-permeant SYTO™ 9 dye and hexidium iodide, gram-negative bacteria fluoresce green and gram-positive bacteria fluoresce red.
