Rhodamine 110 (R110) azide for click chemistry, pure 6-isomer.

Rhodamine 6G is a xanthene dye that has been used for DNA sequencing and qPCR. This azide derivative is used for the attachment of the dye to DNA and other molecules by means of click chemistry.

Highly sensitive and selective reagent for fluorometric quantification of protein concentration, using both fluorescence microplate readers and cuvette-based devices. The dye is highly tolerant to non-protein impurities, except surface acting agents.

Random-sequence oligonucleotide can be used as a universal primer.

Phosphoramidite for synthesis of oligonucleotides labeled at the 5′-terminus with rhodamine 6G (R6G). Pure 6-isomer.

R6G (rhodamine 6G) NHS ester, pure 5-isomer. This dye is often used for the labeling of oligonucleotides for qPCR.

An alkyne derivative of bright red-emitting dye ROX (Rhodamine X, Rhodamine 101) for copper-catalyzed click chemistry bioconjugation. Pure 6-isomer.

Fast-response potential-sensitive fluorescent probe for imaging functional activity of mitochondria, neurons, and heart cells.

Azide derivative of ROX (Rhodamine X, Rhodamine 101) dye for biomolecule labeling via click chemistry. Pure 5-isomer.

Retinol-d5 is a biologically active form of fat-soluble vitamin A, with a stable deuterium label for quantitative studies by MS methods.
