Abcam Coomassie Brilliant Blue R-250 Protein Stain, 25G
MW 825.99 g/mol. Triphenylmethane dye used in SDS-PAGE for the analysis of proteins. The dye molecule binds to proteins to form a protein-dye complex. This complex stabilizes the negatively charged anionic form of the dye producing the blue color, even under acidic conditions.

Biotium DIHYDROETHIDIUM (HYDROETHIDIUM)
Dihydroethidium (also called hydroethidium) is the chemically reduced form of the commonly used DNA dye ethidium bromide. The probe is useful to detect oxidative activities in viable cells, including respiratory burst in phagocytes. Dihydroethidium itself has blue fluorescence Ex/Em: 355/420nm) in cells, while the oxidized form ethidium has red fluorescence Ex/Em: 518/605 nm) upon DNA intercalation.Properties: Off-white to light brown solid soluble in DMF or DMSO; Store at -20°C under nitrogen or argon, and protect from light, especially when in solution; C21H21N3; MW: 315; [38483-26-0]

Biotium DAPI, 10mg/mL in H2O
DAPI (4',6-Diamidino-2-Phenylindole) is a popular blue DNA dye that is used as a nuclear counterstain in fluorescence microscopy, chromosome staining and flow cytometry. The dye binds to the minor groove of dsDNA with approximately 20-fold fluorescence enhancement, with higher affinity for A-T rich regions. Because of the potential toxicity of DAPI, we offer DAPI dilactate dissolved in H2O as a safer alternative to weighing out the powdery form. We also offer DAPI dilactate solid, which is more water soluble than the dihydrochloride form of the dye. Classic blue nuclear counterstain for fixed cells Can be used at higher concentrations to stain live cells &lamba;Ex/&lamba;Em (with DNA) = 358/461 nm Yellow solution Store at 4°C and protect from light C22H27N5O6 MW: 457.49
Biotium PMA 1MG
PMA (propidium monoazide) is a high affinity photoreactive DNA binding dye invented by scientists at Biotium for viability PCR of bacteria and other organisms. It preferentially binds to dsDNA with high affinity. Upon photolysis, the dye covalently reacts with DNA, thus resulting in permanent DNA modification. The dye is cell membrane-impermeable, and thus can be selectively used to modify only exposed DNA from dead cells while leaving DNA from viable cells intact. This feature allows selective detection of viable pathogenic cells by quantitative real-time PCR in the presence dead cells whose DNA has been PMA-modified and thus can not be amplified. PMA has been used extensively in bacterial detection related to food and water safety, medical diagnosis and biodefense. 1 mg Molecular weight: 511 Abs = 464 nm (before photolysis) Abs/Em = 510/610 nm (following reaction with DNA/RNA) Dark red solid soluble in DMSO or DMF Store at 4�C and protect from light at all times
