Tan H, Qiu Y, Chen S, Chen X, Wu Y, He S, Li X, Chen H. A rapid immunomagnetic beads-based sELISA method for the detection of bovine αs1-casein based on specific epitopes. Food Chem 2024; 444:138565. [PMID: 38340505 DOI: 10.1016/j.foodchem.2024.138565] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/26/2023] [Revised: 01/15/2024] [Accepted: 01/22/2024] [Indexed: 02/12/2024]
Abstract
Although αs1-casein poses significant health risks to individuals with milk allergies, the availability of quantification methods for this allergen remains limited. In this study, we developed an immunomagnetic beads-based immunoassay (IMBs-ELISA) for the precise quantitative detection of bovine αs1-CN, specifically targeting epitope AA173-194. No cross-reactivity was observed with the other 7 food allergens including milk allergen. The linear detection range of the established IMBs-ELISA method was 0.125 μg/mL-2.000 μg/mL, with a limit of detection of 0.099 μg/mL. The accuracy of this method was 1.048 %, and the intra-plate and inter-plate precision achieved 4.100 % and 6.777 %, respectively. Notably, the entire IMBs-ELISA process could be completed within 75 min, representing a substantial time-saving advantage over traditional ELISA methods. These results proved the reliability and rapidity of the IMBs-ELISA method for detecting αs1-CN in real food.

[PMID: 37935975 DOI: 10.1007/s00203-023-03713-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/12/2023] [Revised: 10/14/2023] [Accepted: 10/16/2023] [Indexed: 11/09/2023]
Abstract
Microbial proteases are enzymes secreted by a variety of microorganisms, including bacteria and fungi, and have attracted significant attention due to their versatile applications in the food and pharmaceutical industries. In addition, certain proteases have been used in the development of skin health products and cosmetics. This article provides a review of microbial proteases in terms of their classification, sources, properties, and applications. Moreover, different pharmacological and molecular investigations have been reviewed. Various biological activities of microbial proteases, such as Arazyme, collagenase, elastin, and Nattokinase, which are involved in the digestion of dietary proteins, as well as their potential anti-inflammatory, anti-cancer, antithrombotic, and immunomodulatory effects have been included. Furthermore, their ability to control infections and treat various disorders has been discussed. Finally, this review highlights the potential applications and future perspectives of microbial proteases in biotechnology and biomedicine, and proposes further studies to develop new perspectives for disease control and health-promoting strategies using microbial resources.
