Water soluble sulfo-Cyanine3 SE activated ester for amino-biomolecule labeling.

Conjugate of hydrophilic sulfo-Cyanine3 dye with biotin, affinity label for avidin/streptavidin.

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.

Azide of green-yellow emitting dye SIMA for conjugation with oligonucleotides via [3+2]-dipolar cycloaddition.

Derivative of SIMA fluorophore with non-activated free carboxylic acid group.

Phosphoramidite for synthesis of oligonucleotides labeled with SIMA in the middle of sequence.
