FD Apop™ Kit is designed for the microscopic detection of cells undergoing apoptosis based on the principle of in situ DNA nick-end labeling (TUNEL) technique1. The assay uses terminal deoxynucleotidyl transferase to catalyze the incorporation of biotinylated deoxyuridines onto the free 3′-hydroxyl termini of DNA fragments, which are considered one of the most characteristic features of apoptosis2, 3. The integrated biotins are amplified and visualized with the avidin-biotin-complex (ABC) method4, enabling light microscopic identification.

The reagents and procedure of FD Apop™ Kit have been optimized to achieve a high degree of both specificity and sensitivity for detecting apoptotic cells with minimal background. This kit can be used with frozen and paraffin sections, as well as cultured cells. The procedure of the kit takes approximately 4 hours.

艾美捷FD NeuroTechFD Apop TUNEL凋亡檢測試劑盒（#PK101）設計用于基于原位DNA切口標記（TUNEL）技術原理的細胞凋亡的顯微鏡檢測。該測定使用末端脫氧核苷酸轉移酶催化生物-素化脫氧尿苷摻入DNA片段的游離3′-羥基末端，這被認為是細胞凋亡極為典型的特征之一2, 3.整合的生物-素通過親和素-生物-素復合物（ABC）方法進行擴增和可視化4，可實現光學顯微鏡識別。

FD NeuroTech FD Apop TUNEL凋亡檢測試劑盒的試劑和程序已經過優化，可實現高度的特異性和靈敏度，以極小的背景檢測凋亡細胞。該試劑盒可用于冷凍和石蠟切片以及培養細胞。該套件的過程大約需要 4 小時。
