With a broad range of excitation wavelengths, R-PE can be easily excited by two laser sources (488 nm & 561 nm), and used in most fluorescence detection applications, e.g. Flow Cytometry (FC), Immunofluorescence microscopy (IF), and Microarrays. Home Algae's R-PE absorbance maxima are at 496, 546, and 565 nm, with a resolvable emission peak at 578 nm. It shows minimal fluoresence quenching.
R-PE won't penetrate into the cell and cause a false-positive reaction.
R-PE has multiple sites for stable conjugation with Biotin, Streptavidin, and other fluorophores, e.g., Cy-3, Cy-5, Cy-7.
Non-toxic, with less chance of affecting characteristics of the sample, human body, and environment.
