Haoqinbio provides scientists with multiplex protein biomarker assays for cycIF.

With our patented SelfAmp technology, we have eliminated the limitation on the number of detected protein targets while amplifying the signal.

SelfAmp™ technology utilizes a mixture of DNA barcoded antibodies. After binding to the antigens and amplification, those antibodies are attached by fluorescent probes, which can be visualized using a fluorescence microscope.

Due to the spontaneous amplification without the need for any additional nucleic acid strands, there is no Cross-Reactivity within the barcoded DNA. So we can mix as many DNA barcode antibodies as possible.
