为践行科教协同育人理念,该文设计了猪尿中沙丁胺醇免疫层析技术性能提升综合实验。基于小分子竞争反应原理,通过制备不同粒径的胶体金溶液,对探针标记pH值、抗体用量、封闭剂等关键因素进行设计与优化,建立了猪尿中沙丁胺醇的胶体金免疫层析快速检测技术。该方法的cut-off值为3 ng/mL,灵敏度媲美市场同类产品。通过免疫层析技术全过程的设计与实践,提高了教学内容的前沿性和应用性,使学生可以深入系统地掌握该技术的原理和研发过程,培养学生的科研创新和实践能力。同时将思政元素引入实验教学中,培养学生矢志不渝、辩证分析以及团队合作的科研精神。
To implement the concept of integrating scientific research and education,a comprehensive experiment was designed to improve the performance of immunochromatography for salbutamol in swine urine. Based on the principle of small molecule competitive reaction,different sizes of colloidal gold were prepared. The key factors affecting the method's performance,such as labeling pH,antibody amount,and blocking agent,were designed and optimized. A rapid immunochromatography based on colloidal gold for salbutamol in swine urine was established. The cut-off value of the method was 3 ng/mL,with sensitivity comparable to similar products on the market. Through the entire design and practice of the immunochromatography,the frontiers and practical applicability of teaching contents were enhanced,enabling students to thoroughly understand the principles and development process of this technology,thus cultivating their abilities in scientific research innovation and practical application. Moreover,ideological and political education elements were introduced into experimental teaching to foster students' unwavering commitment,dialectical analysis skills,and teamwork spirit in scientific research.
