CF®532 is a green fluorescent dye with absorption/emission at 527/558 nm (Figure 1). Developed by Biotium, it’s a new rhodamine dye that’s bright, photostable, and highly water-soluble. CF®532 antibody conjugates are exceptionally soluble and brighter than similar dyes like Alexa Fluor® 532 (Figures 2, 3).
