Abstract
2021 year 8 month 24 On [date], the Biochemistry Group of the company’s Quality Control Department conducted an activity in the company’s biochemistry laboratory. Lowry “Protein Content Assay Skills Competition” event. With the theme “Strengthening Fundamentals, Striving for Excellence,” this competition aims to establish a platform for exchange and learning, foster skill‑sharing, build camaraderie, and enhance the assay expertise of the Biochemistry Testing Group within the Quality Control Department, thereby ensuring robust product quality control across the enterprise. The event is coordinated by the Trade Union, supervised by Human Resources, and implemented by the Quality Control Department. Attending the competition were Liu Cui, Manager of the Quality Control Department; Zhang Ning, Deputy Manager of the Human Resources Department; Ma Hongjuan, Senior Supervisor of the Trade Union; as well as all members of the Biochemistry Testing Group of the Quality Control Department.
This competition will be conducted in an open, fair, and transparent manner, with participants divided into… 6 Group, each group consists of 2-3 People, contestants based on Lowry The protein content was determined in accordance with the standard operating procedure for protein assay, and each participant took… 1 One internal quality control sample and one blind sample are prepared, with each group commencing simultaneously. Lowry Detection of protein content in food. Lowry The determination of protein content by UV spectrophotometry serves as the foundation for quantitative experiments, assessing the analyst’s experimental technique and attention to detail. Biological experiments involve biological processes and materials, which inherently exhibit variability, thereby placing higher demands on the operator compared to other types of quantitative assays. Ultimately, the correlation coefficient of the standard curve ( r2 ≥ 0.9900 , the closer it is to 1 The better ) , Protein internal control range (41~46 district g/ml , the closer it is to 43.5 district g/ml The rankings were determined based on the accuracy of the results (the closer to the initial values, the better) and the blind‑sample outcomes (the closer to the initial results, the better). After a day of intense competition, Qi Qiuhuan from the Quality Control Department took first place, Wang Lin placed second, and Wang Zhijuan secured third.
After the experiment concluded, Manager Liu Cui convened a debriefing session to review the day’s procedures, analyze each team member’s strengths and weaknesses, and standardize operational details. The participants gained valuable insights, recognizing that they still need to further enhance their skills in biochemical experiments and adhere strictly to… GMP In accordance with the requirements, we adopt a conscientious and responsible approach, meticulously attend to every experimental detail, and strive for continuous improvement, thereby obtaining more accurate and reliable experimental results and ensuring the quality of our company’s products.
