Denaturing Urea Polyacrylamide Gel Electrophoresis (Urea PAGE)

Overview

Denaturing urea polyacrylamide gel electrophoresis is a technique used to separate single-stranded DNA or RNA fragments. This method relies on the combination of urea and heat to denature samples, allowing unstructured single strands to migrate through the gel matrix based on their molecular weight.
