我们描述了一种自动化的方法来分离突变体C。elegans动物,这些动物不能适当地执行我们用基于GFP的报告基因技术监测的细胞分化程序。在COPAS Biosort机器中实施的荧光激活分选机制能够分离具有gfp表达的细胞特异性的细微改变的突变体。这种方法比类似的手动筛选更有效,使我们能够分离出多巴胺神经元不能适当分化的突变体。
We describe an automated method to isolate mutant C. elegans animals, which fail to appropriately execute a cellular differentiation program that we monitor with gfp-based reporter gene technology. A fluorescence activated sorting mechanism implemented in the COPAS Biosort machine is able to isolate mutants with subtle alterations in the cellular specificity of gfp expression. This methodology is significantly more efficient than comparable manual screens and enabled us to isolate mutants in which dopamine neurons fail to differentiate appropriately.
