Description | 1. CAPS buffer with pH of 11, is a buffer that is commonly used in sequencing and amino acid analysis applications. As the pH is 11, this buffer can be used for the blotting of proteins with a pl ≥8.5. 2. CAPS buffer is recommended for tank transfer systems. In semi-dry transfer, it may produce variable transfer efficiency. 3. CAPS is an alkaline buffer for protein transfer after SDS polyacrylamide gel electrophoresis on nitrocellulose filters. |
