Used for high-resolution protein separation in SDS-PAGE electrophoresis, particularly ideal for achieving sharp, well-defined bands (HD band) in molecular weight range around 10–150 kDa. The pre-cast 12% acrylamide gel ensures consistent performance and reproducibility, eliminating manual gel pouring and reducing preparation time. Suitable for western blotting, protein expression analysis, and quality control in research and diagnostic laboratories. The filtration and sterilization process minimizes contamination and ensures long shelf life. Compatible with standard Tris-glycine running buffers and widely used in routine protein analysis.
