In order to mimic this repair process of apoenzyme, we synthesized two model compounds, in which tryptophan and/or tyrosine was covalently linked to cyclobutane thymine dimer, and measured the splitting quantum yield of dimer under 295 nm light. By investigating the photosensitized splitting properties of the dimer, some new insights into the intramolecular electron-transfer process were gained.

為了模擬酶蛋白的這一修復過程，合成了色氨酸和/或酪氨酸與胸腺嘧啶二聚體共價連接的化合物，作為酶-底物復合物的模型，研究了它們在295 nm光照射下氨基酸殘基光敏化二聚體裂解的性質，測定了二聚體裂解量子產率国产AV色浴，獲得一些新的結果并對其進行了分析。

The enzyme amplified lanthanide luminescent spectrometry of horseradish peroxidase was developed and applied to the analyse of HRP and tuberculosis. The deconvolution curve method was used for synchronous fluorimetric determination of two component systems of highly overlapped spectra, such as phenol and p-dihydroxybenzene, phenol and o-dihydroxybenzene, and tyrosine and tryptophan. A novel mathematical method, combining Gorry's deconvolution method, was presented to remedy data loosing of SavitzkyGolay's deconvolution method and applied to dealing with fluorescent signal.
