產(chǎn)品介紹

ROX NHS ester, pure 6- isomer

ROX (rhodamine X aka R101) is a highly fluorescent, and photostable rhodamine dye for various applications. ROX labeled oligonucleotide probes are often used in PCR, and PCR instruments have ROX channel.

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

This dye can replace Alexa Fluor 568, Texas Red.
