ReadiUse™ Preactivated PE-iFluor® 660 Tandem
R-Phycoerythrin (PE) is isolated from red algae. Its primary absorption peak is at 565 nm with secondary peaks at 496 and 545 nm. Our RPE-iFluor® 660 Tandem is an excellent color for multicolor analysis of multiple targets with flow cytometry. It has a unique emission located between the emission Cy5 and that of Cy5.5, providing a new color for spectral flow cytometry. ReadiUse™ Preactivated PE-iFluor® 660 Tandem is an activated PE protein, and can be easily conjugated to antibodies with much higher conjugation yield than the conventional PE.
Our preactivated PE-iFluor® 660 Tandem was premodified with our Buccutite™ FOL (provided). Your antibody (or other proteins) is modified with our Buccutite™ MTA (provided as free sample) to give MTA-modified protein (such as antibody). The MTA-modified protein readily reacts with FOL-modified PE-iFluor® 660 Tandem (provided) to give the desired PE-iFluor® 660 Tandem-antibody conjugate in much higher yield than the SMCC chemistry. In addition our preactivated PE-iFluor® 660 Tandem reacts with MTA-modified biopolymers at much lower concentrations than the SMCC chemistry.
