Used for high-resolution separation of proteins in the molecular weight range of approximately 10–250 kDa. Ideal for resolving closely sized proteins in research and diagnostic applications. Commonly used in Western blotting workflows to transfer proteins for immunodetection. Provides consistent gel quality for reproducible electrophoretic results. Suitable for both denaturing and native PAGE depending on sample preparation. Compatible with standard electrophoresis buffers and staining methods such as Coomassie Blue or silver staining.
