Abstract

Native fluorescence spectroscopy of normal human oral and malignant epithelial cells was studied under uv excitation. Differences were observed in the excitation spectra between normal and malignant epithelial cells for 340 nm emission. The observed differences may be utilized for both discrimination and changes associated with the amino acid residues in the cellular proteins.

正常和恶性上皮细胞的天然荧光光谱。
研究了正常人口腔上皮细胞和恶性上皮细胞在紫外光激发下的天然荧光光谱。正常上皮细胞和恶性上皮细胞在340 nm发射时的激发光谱存在差异。所观察到的差异可用于细胞蛋白中氨基酸残基的鉴别和相关变化。
