Abstract

Abstract: Semiconductor quantum dots were used for the first time to label trichosanthin. The absorption spectrum, fluorescent spectrum and enzymatic activity of quantum dots-labeled trichosanthin were studied in this paper. The absorbane of QDs-TCSvaried to a less extent with wavelength in the range of 400-600 nm. The fluorescent spectrum of QDs-TCSunderwent a blue-shift in the emission peak, but the intrinsic spectral width was unchanged. No changes were found in the enzymatic activity of QDs-TCSin comparison with trichosanthin. Distribution of QDs-TCSwithin human choriocarcinoma cells was simultaneously observed with two-photon laser scanning microscopy and confocal laser scanning microscopy. The results indicated that QDs-TCScould enter the cytoplasm across the membrane and aggregated around the nuleolus.
