    摘要: Embodiments of a composition for stabilizing fluorescent signal of nanoparticles and methods for its use are disclosed. In some embodiments, the composition has a pH from 7 to 10 and includes borate, protein and/or protein hydrolysate, an amine, a preservative, and a nonionic surfactant. In particular embodiments, the amine is an N-ethanol substituted amine, such as ethanolamine, diethanolamine, triethanolamine, N-methyldiethanolamine, N,N-dimethylethanolamine, or a combination thereof. In some embodiments, a fluorescent particle solution, such as a quantum dot solution or quantum dot conjugate solution, is diluted in the composition and stored at 4° C. In certain embodiments, the fluorescence intensity of the diluted fluorescent particle remains substantially the same when stored at 4° C. for at least one month or at least three months. In particular embodiments, a diluted quantum dot conjugate is used to detect a hybridized probe or a protein antigen.

    摘要: The present invention provides a method and kit for detection of two or more target molecules in a single tissue sample, such as for gene and protein dual detection in a single tissue sample. Methods comprise treating a tissue sample with a first binding moiety that specifically binds a first target molecule. Methods further comprise treating the tissue sample with a solution containing a soluble electron-rich aromatic compound prior to or concomitantly with contacting the tissue sample with a hapten-labeled binding moiety and detecting a second target molecule. In one example, the first target molecule is a protein and the second is a nucleic acid sequence, the first target molecule being detected by immunohistochemistry and the second by in situ hybridization. The disclosed method reduces background due to non-specific binding of the hapten-labeled specific binding moiety to an insoluble electron rich compound deposited near the first target molecule.
