Ac-DEVD-AFC is a fluorogenic substrate for activated caspase-3 (CPP32) with Km value of 9.7 μM, and related cysteine proteases [1][2].
Apoptosis is a process of programmed cell death that occurs in multicellular organisms. Caspase are a family of protease enzymes playing essential roles in programmed cell death (including apoptosis, pyroptosis and necroptosis) and inflammation. Caspase activation is a major event in apoptosis. Caspase-3 cleaves and activates caspases 6 and 7, and is processed and activated by caspases 8, 9, and 10 [1][2][3].
Ac-DEVD-AFC (N-Acetyl-Asp-Glu-Val-Asp-7-amido-4-Trifluoromethylcoumarin) is a fluorogenic substrate for activated caspase-3 and related caspases. During apoptosis, activated caspase-3 cleaves poly (ADP-ribose) polymerase, which it specifically targets at the amino sequence Asp-Glu-Val-Asp (DEVD). Sequence is based on PARP cleavage at Asp216 for caspase-3 [1][2]. Caspase activity can be quantified by fluorescent detection of free AFC (7-amino-4-trifluoromethylcoumarin) at excitation 400 nm and emission 505 nm [2].

希望有大神赐教!谢谢!
指导意见:
毕竟阴道上皮是鳞状上皮,而输尿管,膀胱,尿道的上皮是柱状上皮,形态上是不一样的.所以您要是对您的结果出怀疑态度,首先:重新留尿,做一个复检(留尿时注意防止阴道分泌物污染);或者让值班医生分析一下是那种类型的上皮(鳞状还是柱状).所以不要担心这个结果.一般情况下污染的比较多.
病情描述(发病时间、主要症状等):
体检血常规中血小板计数343.血小板比积0.39.
尿检中白细胞计数26.2.上皮细胞计数10.30
心电图下写窦性心律,p-r间期偏短
