    • A method is for determining the number of cells in cell culture is provided. In practicing the method, the cells are lysed and incubated at about 18.degree. C. to 25.degree. C. at acid pH with a benzothiazole substrate for a sufficient time to generate detectable fluorescence that is proportional to cell number, and then measuring fluorescence. The method is highly sensitive and can detect small differences or changes in cell number. Thus, the method can be used in drug screening assays. An automated high throughput screening assay for identifying compounds that modulate angiogenesis using the method is also provided.
    • 一种用于确定提供细胞培养物中的细胞数量的方法。 在实施该方法时,将细胞裂解并在酸性pH下用苯并噻唑底物在约18℃至25℃温育足够的时间以产生与细胞数成正比的可检测的荧光,然后测量荧光。 该方法高度敏感,可以检测细胞数量的小差异或变化。 因此,该方法可用于药物筛选测定。 还提供了用于鉴定使用该方法调节血管发生的化合物的自动化高通量筛选测定法。
