ROX Reference Dye is an inert fluorescent dye used in real-time PCR (qPCR) or RT-PCR to normalize fluorescence signals between wells. It does not participate in the PCR reaction and maintains a stable fluorescence signal throughout the process。ROX dye can correct for variations in fluorescence signals caused by uneven lighting, differences in well optics (such as droplets, bubbles), and variations in reaction mixture concentration。

CY5-SE (Cy5 NHS Ester) is a reactive dye used to label amino groups in peptides, proteins and nucleotides. It needs to be stored away from light. Excitation wavelength (nm): 640, emission wavelength (nm): 664.

Methylene Blue trihydrate (Basic blue 9) is a compound consisting of dark green crystals or crystalline powder, having a bronze-like luster. Solutions in water or alcohol have a deep blue color. Methylene Blue trihydrate is used as a bacteriologic stain and as an indicator. It inhibits soluble guanylyl cyclase and has been used to treat cyanide poisoning and to lower levels of methemoglobin. It also inhibits tau filament formation (IC50: 1.9μM).
