Gram Staining – Fast Differentiation of Gram-positive and Gram-negative

CDX-P0023 25 mg | 500 mg | 5 g

The most common red-fluorescent nuclear stain. Membrane-impermeant and generally excluded from viable cells. It can easily penetrate dead or damaged cells and as such is commonly used for identifying cell viability in a population or as a counterstain in multicolor fluorescent techniques. It binds to DNA and RNA by intercalating between the bases. Spectral Properties: lex 488-535 nm; lem 617 nm.

PRODUCT NAME	SUK	DESCRIPTION
Acridine Orange HCl hydrate	A0005	Cell-permeable metachromatic fluorescent dye that stains DNA and RNA.
DAPI 2HCl	D0025	Cell-permeable, fluorescent dye that is a minor groove-binding probe for DNA.
Ethidium homodimer	E0012	Staining dye for ssDNA, dsDNA, RNA, oligonucleotides and triplex DNA. It does not cross intact cell membranes and can be used to test cell viability.
Ethidium bromide	E0005	Commonly used nucleic acid stain for PAGE or agarose gel electrophoresis.
Hoechst 33258	B0029	Useful for staining DNA, chromosomes and nuclei. For determining the DNA content of viable cells without detergent treatment or fixation.

Other Cell Viability Dyes

PRODUCT NAME	SUK	DESCRIPTION
Calcein-AM	C0009	Non-fluorescent cell-permeable and hydrophobic probe that, upon entering live cells, is cleaved by intracellular esterases, releasing the membrane-impermeable, hydrophilic and intensely bright green fluorescent calcein.
5(6)-CFDA N-succinimidyl ester	C0037	Useful fluorescent tracer that can passively diffuse into cells and covalently label intracellular proteins, resulting in long-term cell labeling. The reagent itself is colorless and nonfluorescent but becomes brightly green fluorescent once it is hydrolyzed by intracellular esterases.
Fluorescein dioctanoate	F0087	Non-fluorescent hydrophobic fluorescein derivative that can pass through the cell membrane whereupon intracellular esterases hydrolyze the dioctanoate group producing the highly fluorescent product fluorescein.
Resorufin-isobutyrate	I0005	Cell-permeable resorufin derivative used as a fluorogenic indicator for cell viability.
