The Promokine Bioluminescent Cell Viability Kit I employs bioluminescence to measure the ATP level as a marker for cell viability in mammalian cells. It utilizes the enzyme luciferase to catalyze the ATP-dependent, light-producing oxidation of luciferin. This light formation can be measured using a luminometer or beta counter.The assay can be performed directly in culture plates requiring no harvest, washing, or sample preparation and can be fully automated for high throughput (10 seconds/sample). It is highly sensitive, detecting 10-100 mammalian cells/well, and it also offers new applications besides cell viability testing, e.g., detecting low level bacterial contamination in blood, milk, urine, soil, and sludge.

PromoKine细胞生物学(Cell Biology)是在显微、亚显微和分子水平三个层次上，研究细胞的结构、功能和各种生命规律的一门科学。细胞生物学由细胞学发展而来，细胞学是关于细胞结构与功能(特别是染色体)的研究。现代细胞生物学从显微水平、超微水平和分子水平等不同层次研究细胞的结构、功能及生命活动。在我国基础学科发展规划中，细胞生物学与分子生物学、神经生物学和生态学并列为生命科学的四大基础学科。
