神经丝(NF)被归类为第四型中间丝,在神经元的细胞质中发现。它们是直径为10纳米、长度为数微米的蛋白质聚合物。它们与微管(约25纳米)和微丝(7纳米)一起构成神经元的细胞骨架。据信它们的功能主要是为轴突提供结构支持,并调节轴突直径,从而影响神经传导速度。形成神经丝的蛋白质是中间丝蛋白家族的成员,根据其基因组织和蛋白质结构分为六种类型。I型和II型是角蛋白,在上皮细胞中表达。第三类包含蛋白Vimentin、Desmin、Peripherin和胶质纤维酸性蛋白(GFAP)。第四类由神经丝蛋白L、M、H和internexin组成,即神经丝蛋白L(低分子量;NFL)、M(中分子量;NFM)和H(高分子量;NFH)。第五型由核苷酸组成,第六型由蛋白巢素组成。 本试剂盒采用双抗体夹心法酶联免疫吸附试验(ELISA)。往预先包被有人神经丝蛋白多肽(NFL)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人神经丝蛋白多肽(NFL)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 Human NFL. 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 Human NFL 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.
