Weiyel Reference Materials
Weiye launched a new product - serum albumin series of standard substances. Serum albumin is a biochemical reagent widely used in many biological disciplines and in various fields of medicine and pharmacy. In the serum-free culture of animal cells, the addition of albumin can play a physiological and mechanical protection and carrier role.

High-purity serum albumin is used as raw material, and after qualitative analysis and preliminary purity analysis meet the requirements, it is divided into vials under sterile and clean environment conditions. And further use a specific solvent to dissolve, and prepare a solution standard substance of corresponding concentration. Refer to JJF1343 National Metrology Technical Specification(equivalent to ISO Guide 35), random sampling is performed on the subpackaged samples, and high performance liquid chromatography is used for the homogeneity test and long-term Stability tracking survey. The results show that the uniformity conforms to the F test rule, and the stability test is good.
Serum albumin series reference materials are mainly used for the traceability and quality control of the measurement results of protein content in food analysis, drug analysis, clinical testing, the calibration of analytical instruments such as nucleic acid and protein analyzers, and the confirmation and evaluation of related methods.
Serum albumin series reference materials should be frozen and protected from light, and the solution should be stored in cold storage and protected from light. Before use, it should be equilibrated at room temperature (20±3℃) and shaken sufficiently to ensure uniformity. Once the ampoule is opened, it should be used immediately. It should not be used as reference materials after being melted and sealed again. Strictly prevent contamination during use.
