2,4,5,6 tetraaminopyrimidine

2,4,5,6-Tetraaminopyrimidine is a coloring agent.

bis-ANS is a high-affinity non-covalent extrinsic fluorescent dye used to analyze protein conformation.[1] Its predominant interaction with proteins is through its hydrophobic phenyl and naphthyl rings.[2] bis-ANS has an excitation maxima of 390 nm.[3] It has an emission maximum of 523 nm when free in solution but undergoes a blue shift with an increase in fluorescence intensity when bound to protein; for example, when bound to intestinal fatty acid binding protein (FAPB2) it has emission maxima of 484-496 nm. bis-ANS has been used to label mechanically damaged neurons in acute brain slices.4 It also potently inhibits microtubule assembly.[5],[6]

Biotin-11-dUTP [tetra(triethylammonium) salt] [(2S,3S,4R,5R,6R)-5-(2,4-dioxopyrimidin-1-yl)-4-hydroxy-6-(hydroxymethyl)-2-[(3aR,4S,6R,6aS)-2-oxohexahydro-2H-thieno[3,4-d]imidazol-4-yl]-tetrahydro-2H-furo[3,2-d][1,3,2]dioxaphosphorin-3-yl]phosphonate] is used as a fluorescent substitute for dTTP.

CelRed nucleic acid gel stain 10,000× concentrate in water is a fluorescent dye used for nucleic acid staining, suitable for staining and detecting dsDNA, ssDNA, or RNA in agarose gels or polyacrylamide gels.
