Factor Xa (FXa) is a serine endopeptidase composed of two disulfide-linked subunits. FXa leads to blood clot formation by converting prothrombin to thrombin through the prothrombinase complex. FXa is generated from zymogen Factor X via the intrinsic and extrinsic pathways and is the rate-limiting step in the propagation of thrombin generation. In the presence of Ca2+ ions, FXa forms prothrombinase with factor Va on the phospholipid membrane of the activated platelets. FXa has emerged as an attractive target for drug discovery for thromboembolic diseases. The SensoLyte® 520 Factor Xa Assay Kit provides a convenient assay for high throughput screening of FXa inhibitors or continuous assay of enzyme activity. It detects FXa activity using a 5-FAM/QXL® 520 fluorescence resonance energy transfer (FRET) peptide. In the intact FRET peptide, the fluorescence of 5-FAM is quenched by QXL® 520.Upon cleavage into two separate fragments by FXa, the fluorescence of 5-FAM is recovered, and can be monitored at excitation/emission wavelengths = 490 nm/520 nm. With excellent fluorescence quantum yield and longer wavelength, 5-FAM shows less interference from autofluorescence of test compounds and cellular components. The assays are performed in a convenient 96-well microplate format. Kit size: 100 assays | |

而方波是一种数字信号，其电信号在一应时间内保持持续稳定的点击，并在点击后瞬间消失，对细胞的损伤较小，转化效率较高。
t=RC，其中t是时程，R是电阻，C是电容，我不知道这个电阻是不是电转杯的电阻还是电转仪本身有个电阻，如果有哪位大侠知道能不能告诉?

表皮分布于幼嫩的根、茎、叶、花、果实和种子的表面，通常是一层由初生分生组织的原表皮分化而来的生活细胞（夹竹桃等植物的叶上表皮，具有多层生活细胞所组成的复表皮），是保护植株免于风、雨、病原微生物和虫害等伤害的初生保护组织。表皮以表皮细胞为主，另有保卫细胞、副卫细胞及外生物等，有些植物的表皮中还有特化的异细胞。表皮的形态特征是物种鉴定的依据之一。
