Oligonucleotide labeling and dyes for test kits

6-ROX NHS-ester

Pure single isomer for the labeling of amino-groups in peptides, proteins, and amino-oligonucleotides.

ROX (also known as rhodamine X or R101) is a highly fluorescent, and photostable rhodamine dye for various applications. ROX labeled oligonucleotide probes are often used in qPCR.

ROX Reference Dye for qPCR

Passive reference dye for qPCR application

The ROX dye is recommended for:

• Normalization of fluorescence intensity of qPCR reporter dyes
• Correct for pipeting errors and instrumental drift such as change of lamp intensity output over time

ROX reference dye is compatible with all qPCR instruments with ROX channel. Most instruments require either 500nM or 50nM end concentration of ROX. .

FAM Phosphoramidite, 6-Isomer

Fluorescent dye for synthesis of labeled DNA, RNA, and other nucleic acids.

Standard fluorescein (FAM) phosphoramidite for 5′-terminal oligonucleotide labeling, high isomeric purity single isomer. This highly purified amidite reagent ensures excellent coupling results with various synthesizers..

Quality control: NMR ¹H and ³¹P, HPLC-MS (95+%), isomeric purity > 97%
