核微探针研究纤细裸藻细胞对稀土元素的强摄取性

Euglena gracilis demonstrated remarkable ability to transport rare earth ions to the cell body. Their contents, distributions, valence states in Euglena gracilis and correlation with certain macro-molecule were investigated by microprobe, EPR, SXRF, EXAFS, Raman spectra etc. Calcium channels in the cell were shown by immuno-gold method and fluorescence probe. Summing up the evidences, it could be concluded that L-type calcium channel is an important entryway for rare earth ions on intact cell.
