WebAug 26, 2015 · DNA damage and repair is a fundamental process that plays an important role in cancer treatment. Base excision repair (BER) is a major repair pathway that often leads to drug resistance in DNA-targeted cancer chemotherapy. In order to measure BER, we have developed a near infrared (NIR) fluorescent probe. WebFluorescence is the emission of light by a substance that has absorbed light or other electromagnetic radiation. It is a form of luminescence. In most cases, the emitted light has a longer wavelength, and therefore a lower … kingsfield 4 pc download

Fluorescence - Wikipedia

• Fluorescence microscopy of tissues, cells or subcellular structures is accomplished by labeling an antibody with a fluorophore and allowing the antibody to find its target antigen within the sample. Labeling multiple antibodies with different fluorophores allows visualization of multiple targets within a single image. WebNature Chemistry - The emergence of synthetic fluorescent nucleobases that can be incorporated into DNA and RNA in place of their natural counterparts has enabled new … WebThese instruments measure the intensity of the fluorescent signal from dyes attached to biological molecules as well as naturally fluorescent molecules based on signature excitation (Ex) and emission (Em) wavelengths. Our fluorometers help to simplify fluorescence analysis while conserving precious sample and time. lvdysfunction 医療
