Biology blot tests

WebWestern blotting (or immunoblotting) is a widely used method for protein detection, using antibody-based probes to obtain specific information about target proteins from complex samples. It is a routine method in molecular biology, biochemistry, and cell biology fields with a multitude of applications. WebA mainstay of molecular biology research is the nucleic acid blot. "Blots" are membranes such as nitrocellulose or coated nylon to which nucleic acids have been permanently bound. Blot hybridizations with specific nucleic acid probes provide critical information regarding gene expression and genome structure. The most common blot applications ...
