Gasdermin D(N-端)是Gasdermin家族中参与热化作用的孔隙形成蛋白的一个成员。Gasdermin-D对诱导热化细胞死亡以应对病原体和损伤相关的分子模式至关重要,从而发挥了对先天免疫防御重要的作用。Gasdermin-D以非活性状态定位在细胞膜上,但在炎症性Caspase-1、4或5将其裂解为N和C端片段后,N端片段转移到质膜上,在那里形成大的寡聚物孔。骨髓树突状细胞(BMDCs)、骨髓衍生巨噬细胞(BMDMs)和中性粒细胞分泌促炎症细胞因子IL-1β和IL-18也依赖于Gasdermin-D,通过细胞裂解释放和直接通过其N端片段在质膜上形成孔隙。Gasdermin-D通过其N端与细菌细胞膜的心磷脂结合以及随后的膜穿孔表现出杀菌特性。 本试剂盒采用双抗体夹心法酶联免疫吸附试验(ELISA)。往预先包被有小鼠Gasdermin-D, N末端(GSDMD-N)捕获抗体的微孔中,依次加入样本、标准品、生物素标记的检测抗体,HRP酶结合物,中间经过温育和洗涤,用底物TMB显色,TMB在过氧化物酶(HRP)的催化下转化成蓝色,并在酸的作用下转化成最终的黄色。颜色的深浅和样本中的小鼠Gasdermin-D, N末端(GSDMD-N)呈正相关。用酶标仪在450nm 波长下测定吸光度(OD值),计算样本浓度。
This kit employs the sandwich enzyme-linked immunosorbent assay (ELISA) principle. Microplate wells are pre-coated with a capture antibody specific to Mouse GSDMD-N. Following this, the sample, standards, a biotin-conjugated detection antibody, and an HRP (horseradish peroxidase)-labeled conjugate are added sequentially to the wells. The procedure involves incubation and wash steps between each addition. For detection, TMB substrate is used. TMB yields a blue color in the presence of the peroxidase activity of HRP. The reaction is then stopped with an acid solution, which converts the blue color to a final yellow color. The intensity of the yellow color is directly proportional to the concentration of Mouse GSDMD-N present in the sample. The optical density (OD) is measured at a wavelength of 450 nm using a microplate reader. Finally, the concentration of the target analyte in the sample is calculated based on the standard curve generated from the standards.
