Aat Bioquest 7-Hydroxy-4-methylcoumarin [4-Methylumbelliferone] *Fluorescence reference standard*
This compound is used as a calibration standard for 7-hydroxy-4-methylcoumarin-based enzyme substrates. It has pH-dependent fluorescence.
Biotium DNP Tyramide
DNP tyramide conjugates can be used for tyramide signal amplification (TSA), which is an enzyme-mediated detection method that uses horseradish peroxidase (HRP) to generate high-density labeling of a target protein or nucleic acid in situ.
Sartorius Incucyte Mouse IgG2a
Incucyte Mouse IgG2a Fabfluor Antibody Labeling Dye is designed for quick easy labeling of Fc containing test antibodies with a green or red fluorophore. Once labeled the Fabfluor-antibody complex can be used for identification of surface expressed antigens in live cells. In the absence of expressed specific antigen little or no signal is seen on the cells. With the Incucyte integrated analysis software background fluorescence is minimized.
Biotium 5-(AND-6)-CARBOXYTetramethylrhodamine SU
5(6)-TAMRA SE (full name: 5-(and-6)-Carboxytetramethylrhodamine succinimidyl ester (mixed isomers)) is the amine reactive form of TAMRA, one of the most commonly used red fluorescent dyes. The succinimidyl ester reacts readily with primary or secondary amines under mild conditions. Properties: Ex/Em (MeOH) = 540/565 nm; e = 95,000; Red solid soluble in DMF or DMSO; Store at -20°C and protect from light; C 29 H 25 N 3 O 7; MW: 527.5; [150408-83-6]
Aat Bioquest Fluorescein-5-maleimide *CAS 75350-46-8*
Maleimides are among the most frequently used reagents for thiol modification. In most proteins, the site of reaction is at cysteine residues that either are intrinsically present or resulted from reduction of cystines.
Aat Bioquest Cyanine 5 amine [equivalent to Cy5® amine]
A variety of cyanine 5 ( Cy5®) dyes has been used to label biological molecules for fluorescence imaging and other fluorescence-based biochemical analysis. They are widely used for labeling peptides, proteins and oligos etc.
Biotium CF640R Biocytin
Fluorescent biocytin conjugates are cell-impermeant, fixable polar tracers with biotin and an aldehyde-fixable primary amine groups. Polar tracers are commonly used to investigate cell-cell and cell-liposome fusion as well as membrane permeability and transport through gap junctions or cell uptake during pinocytosis. CF dyes are Biotium's line of next-generation fluorescent dyes with advantages in brightness, photostability, and conjugate specificity compared to other fluorescent dyes. Far-red fluorescent CF640R dye has excitation/emission at 642/662 nm.
Biotium CF514 Succinimidyl Ester
CF Dye Succinimidyl Esters (SE, also known as NHS esters) are amine-reactive fluorescent dyes. SE dyes are commonly used to label antibodies and other proteins on free amine groups, such as lysine residues. CF dyes are Biotium's line of next-generation fluorescent dyes with advantages in brightness, photostability, and conjugate specificity compared to other fluorescent dyes. Green fluorescent CF514 dye has excitation/emission at 516/548 nm.
Biotium MitoView™ 405 (Sample size)
MitoView™ 405 is a blue fluorescent mitochondrial dye for live cells. It has excitation/emission at 398/440 nm for detection in the DAPI or Pacific Blue channels. It is a replacement for our original MitoView™ Blue, with improved photostability.
Biotium Fluorescein Methotrexate, Triammonium Salt, 1mg
Fluorescein methotrexate is useful for studying anti-metabolite resistance and spontaneous gene amplification. The dye is actively taken up by cells and binds to dihydrofolate reductase (DHFR) quantitatively.Properties: Ex/Em nm 496/516 nm; Yellow solid soluble in pH>6.5 buffer, DMF or DMSO; Store desiccated at 4°C and protect from light; C46H54N14O9S; MW:979.08
Lumiprobe Sulfo-Cyanine7 azide, 1 mg
A water-soluble NIR dye azide for Click Chemistry. Sulfo-Cyanine7 is a cyanine dye, an analog of Cy7 with improved photophysical properties. This dye is a perfect choice for NIR imaging studies in live organisms.
