Summary Introduction
Â
To review:
The working principle of western blotting technique.
Introduction:
The manipulation of genes and their expression can be assessed through various molecular techniques like northern blotting, Southern blotting, and western blotting. These techniques function at various molecular levels like DNA (deoxyribonucleic acid), RNA (ribonucleic acid), and proteins. The western blotting technique is able to examine the expression of genes through the detection of their protein products.
