This chemical is primarily used in protein electrophoresis, a technique for separating proteins based on their size. It is particularly useful in research and diagnostic laboratories for analyzing protein samples with high resolution. The precast gel format ensures convenience and consistency, reducing preparation time and variability. It is compatible with various staining and blotting methods, making it versatile for applications such as protein quantification, purity assessment, and biomarker identification. The 4-12% gradient allows for the separation of a wide range of protein molecular weights, while the 15-well design accommodates multiple samples for parallel analysis. Its plastic backing provides durability and ease of handling during electrophoresis and subsequent processing.
