Laboratory gel electrophoresis blotters and accessories are essential tools for transferring proteins or nucleic acids from gels onto membranes for further analysis, typically through Western, Southern, or Northern blotting techniques. Blotting accessories include transfer cassettes, membranes, buffers, and power supplies, which facilitate the movement of biomolecules from the gel to a solid membrane under an electric current. Once transferred, these molecules can be probed with specific antibodies or labelled nucleic acids to detect, quantify, or identify proteins, DNA, or RNA. Blotting is a critical step in molecular biology and biochemistry for verifying the presence of specific molecules in a sample and for studying gene expression or protein modifications. The precision and reliability of blotters and accessories ensure accurate, reproducible results in research and diagnostics.
