Biotech Proteintech announces new line of highly validated conjugated antibodies

ROSEMONT, Ill.–()–Proteintech, the benchmark in antibodies and proteins, announces the launch of over 500 antibodies directly conjugated with high-performance CoraLite®488 and CoraLite®594 dyes.

The rapid expansion of biomarkers and microscopic methods has led to an increased demand for multiplex imaging of specific proteins. Unfortunately, it is technically challenging to image using more than 2 unconjugated antibodies. To solve this issue, Proteintech now offers its same KD/KO validated and highly published antibodies in an off-the-shelf directly conjugated form to CoraLite® dyes.

“It is great to be able to save our customers’ time by offering our highly validated products that are conjugated for their immediate use,” said Jeff Lee, Proteintech Chief Operating Officer, “we plan to continue to grow this portfolio with daily launches of new conjugations.”

Proteintech’s CoraLite® conjugated antibodies have the most validation in the market, including genetic manipulation to confirm specificity. Having highly validated, specific antibodies directly conjugated to dyes simplifies multiplex imaging and accelerates the immunostaining procedure. CoraLite® dyes fluoresce at the most frequently excitation wavelengths of 488 and 594 nm to integrate easily into the majority of fluorescent microscope workflows. They are high performance dyes with identical activity as the leading competitor. For a product listing, please visit
