ViaGram™ Red⁺ Bacterial Gram Stain and Viability Kit (Invitrogen™)

The ViaGram™ Red⁺ Bacterial Gram Stain and Viability Kit provides a simple fluorescent staining protocol for fluorescence microscopy that differentially stains many gram-positive and gram-negative bacterial species and, at the same time, discriminates live from dead cells on the basis of plasma membrane integrity.
