抗菌肽PR-39(PR-39)来源于嗜中性粒细胞等免疫细胞，是含有39个氨基酸残基的cathelicidin家族抗菌肽。Cathelicidin是一个最大的抗菌肽家族，有PR-39，PG1-5，PF 1-2和PMAPs 9种抗菌肽，其中PR-39和Protegrin-1是比较重要的2种。它能诱导合成Syndecan-1（一种跨膜的肝磷脂蛋白多糖）。硫酸盐蛋白多糖参与细胞与基质的相互作用和伤口愈合。 本试剂盒采用竞争法酶联免疫吸附试验（ELISA）。往预先包被有猪抗菌肽PR-39(PR-39)抗原的微孔中，依次加入样本、标准品、Biotin标记的抗体，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猪抗菌肽PR-39(PR-39)呈负相关。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 competitive enzyme-linked immunosorbent assay (ELISA) principle. Microplate wells are pre-coated with Pig PR-39 antigen. The sample, standards, a biotin-labeled antibody, and an HRP enzyme conjugate are then added sequentially to the wells. The procedure includes incubation and wash steps between each addition. TMB substrate is used for color development. In the presence of the peroxidase (HRP) enzyme, TMB is catalyzed to produce a blue color, which is then converted into a final stable yellow color upon the addition of an acid stop solution. The intensity of the resulting yellow color is inversely proportional to the concentration of Pig PR-39 in the sample. The optical density (OD) is measured at a wavelength of 450 nm using a microplate reader, and the concentration of the target analyte in the sample is calculated based on the standard curve.
