Gel Electrophoresis – Consumables – Blotting Membranes

Blotting membranes are essential consumables used in gel electrophoresis, specifically in blotting techniques like Western, Southern, and Northern blotting. These membranes, typically made from materials such as nitrocellulose or polyvinylidene difluoride (PVDF), serve as the solid support to which proteins or nucleic acids are transferred after electrophoresis. Once the molecules are immobilised on the membrane, they can be probed with specific antibodies or nucleic acid probes to detect and quantify target biomolecules. Blotting membranes are available in different pore sizes and chemistries, allowing researchers to select the most suitable type for their specific application. These membranes play a critical role in molecular biology, helping researchers visualise and analyse proteins, DNA, or RNA with precision in research areas such as diagnostics, genetics, and proteomics.
