About GORYO Chemical Inc.

Goryo Chemical, Inc. provides new fluorescent probe for cellular analysis, assay, and imaging. Our fluorescent probe is the solvatochromic probe, called POLARIC™. It can change not only the fluorescent intensity but also the fluorescent wavelength widely by each organelle in living cell. Therefore, just only it can stain both mitochondria as orange and plasma membrane as green, simultaneously. Because, it is chromatic changing probe responsed by the polarity in micro-environment like a living cell.
It is not only use as imaging regents for the cellular analysis or assay but also use as chromatic changing maker for the fluorescent labeling to the protein, peptide, antibody and oligonucleotide for molecularly-targeted drug or immunoassay.
