A highly sensitive stain for post-electrophoresis staining of RNA and single-stranded DNA (ssDNA) in agarose or polyacrylamide gels.

ROX maleimide is a thiol reactive dye derivative based on isomerically bright rhodamine X fluorophore.

Control for chromatography with tandem mass spectrometry for assessment of concentrations in biological samples.

Activated NHS ester of ROX (rhodamine X or rhodamine 101), pure 5-isomer, for the labeling of amine groups of biomolecules.

Pure 6-isomer of ROX (Rhodamine X, R101) NHS-ester for amine labeling.

ROX is a passive reference dye for qPCR amplification. The dye can be used to normalize fluorescence intensity of reporter dye in qPCR.

A tetrazine derivative of bright red-emitting dye ROX (Rhodamine X, Rhodamine 101) for copper-free bioconjugation. Pure 5-isomer.

Serotonin-d4 is deuterium labeled serotonin and intended for use as an internal standard for the quantification of serotonin by LC-MS.
