The detection performance of immunoassay, which is one of the effective methods to monitor PEAA residues in animal urine, has been hindered by high concentration of salt. Herein, we produced one highly salt-tolerant monoclonal antibody (mAb) 3E2 by hybridoma technology. Homologous modelling and molecular docking were used to analyse the antibody salt tolerance mechanism. Results show that the tight hydrophobic binding cavity is the key to high tolerance. Then the mAb 3E2 was used for specific detecting PEAA by enzyme-linked immunosorbent assay (ELISA) with the IC50 value of 0.36 ng mL−1and the LOD value of 0.065 µg L−1. Benefiting from the high salt tolerance of antibodies, swine urine and sheep urine spiked with PEAA can be detected directly by ELISA, and the acceptable recovery rates of 80.1–108.8% were obtained.","PeriodicalId":12300,"journal":{"name":"Food and Agricultural Immunology","volume":null,"pages":null},"PeriodicalIF":3.0,"publicationDate":"2022-07-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45750293","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Hydrolysed collagen has long been used as a functional ingredient, showing multiple physiological activities, including enhancement of immune functions. However, how collagen peptides may affect the immune system still needs further research. This study investigates bone collagen peptides (BCP) immunomodulatory activity on human monocytic THP-1 and human Jurkat T lymphocyte cell lines, using cytokine mRNA expressions as biomarkers. In vitro, gastrointestinal digestion and Caco-2 cell absorption allow obtaining digested and absorbed BCP fractions, respectively, which are tested on immune cells. Results show: (1) Immunostimulatory effect on M0 macrophages, but not on M1 macrophages (lipopolysaccharide (LPS)-activated), (2) Significant T lymphocyte proliferation after incubation with absorbed BCP fraction. (3) Significant increase of anti-inflammatory IL-10 cytokine biomarker. These results suggest that BCP could act as an immunonutrient, modulating the immune response and inflammatory processes.

CP treatments have had effects on the color, pH, lipid oxidation, and microbial quality of different meat products.
