The R-phycoerythrin (PE)-Cy7® tandem conjugate permits simultaneous multicolor labeling and detection of multiple targets with excitation by a 488 nm laser without occupying traditional channels associated with FITC and PE. Alternatively, the PE dye tandem can be excited using a 532 nm or 561 nm laser.
This antibody recognizes the alpha chain alone as well as the alpha/beta heterodimer.
