The Annexin V Apoptosis Detection Kits include an Annexin V conjugate or a tagged Annexin V, respectively, as well as binding buffer and partially also propidium iodide (PI) for differentiating between early apoptotic and necrotic cells. The kits allow a one-step staining procedure that takes only 10 minutes. In addition, the assay can be directly performed on living cells.The Annexin V-Biotin Detection Kit can be used in combination with any streptavidin/avidin-conjugate e.g. steptavidin-HRP or streptavidin coupled to a common fluorescent dye, allowing for colorimetric as well as fluorometric apoptosis detection.

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。
