WebInvitrogen Alexa Fluor 647 dye is a bright, far-red–fluorescent dye with excitation ideally suited for the 594 nm or 633 nm laser lines. For stable signal generation in imaging and flow cytometry, Alexa Fluor 647 dye is pH-insensitive over a wide molar range. WebAlexa Fluor 350 protein conjugates are optimally excited at ~346 nm and produce bright, blue fluorescence at a wavelength slightly shorter than that of AMCA or AMCA conjugates, reducing Alexa Fluor 350 dye’s spectral overlap with … WebTetramethylrhodamine (TRITC) is a bright orange-fluorescent dye with excitation ideally suited to the 532 nm laser line. It is commonly conjugated to antibodies and proteins for cellular imaging applications. ray charles the right time
