Rhodamine Dyes

Rhodamine dyes are membrane-permeable cationic fluorescent probes that specifically recognize mitochondrial membrane potentials, thereby attaching to mitochondria and producing bright fluorescence, and at certain concentrations, rhodamine dyes have low toxicity to cells, so they are commonly used to detect mitochondria in animal cells, plant cells, and microorganisms.

PE-Cy5.5 is a far-red emitting tandem dye designed based on the principle of fluorescence resonance energy transfer (FRET), and is widely used in multicolor flow cytometry. PE-Cy5.5 consists of phycoerythrin (PE) as the energy donor and the cyanine dye Cy5.5 as the energy acceptor. Upon excitation by blue or green laser light, PE absorbs energy and transfers it to Cy5.5 via FRET, ultimately resulting in Cy5.5 emitting characteristic far-red fluorescence (Ex/Em = 450-500 nm/698 nm).

TAMRA azide, 5-isomer is a click chemical containing azide groups that can be used as a linker for TAMRA.
