Real-time qPCR using SYBR Green and melting curve analysis to verify specific product amplification has become a standard laboratory technique for rapid, high throughput gene quantification. An extension of this melting curve method – High Resolution melting analysis (HRMA)– is now doing the sa... Read More
We give a lot of troubleshooting help on DNA and RNA isolation on Bitesize Bio because almost everything we do in molecular biology requires DNA or RNA at the very first step. These days, most labs use commercial kits, which employ spin columns, for the isolation of nucleic acids. The spin colu... Read More
