Upload NowIn this article we will discuss about the principle, requirements and procedure for Polymerase Chain Reaction (PCR). PCR is a simple method for in vitro enzymatic amplification of specific nucleic acids using multiple cycles of template denaturation, primer annealing and primer elongation. From as little as a single piece of target DNA, enough copies can […]

In this article we will discuss about the requirements and procedure for isolation of RNA using Phenol-SDS method. SDS dissociates the ribonucleoprotein complex into RNA and protein, deproteinised by phenol and the free RNA left in aqueous solution is precipitated in cold after adding alcohol. Requirements: Reagents: 1. Extraction buffer-pH 9.0: Tris HCl (0.1 M): […]

In this article we will discuss about the principle, requirements and procedure for purification of DNA. Principle: DNA is removed from gel by dissolving the gel in cesium chloride and DNA is taken out with ethidium bromide in T.E. buffer, centrifuged and DNA is removed. Ethidium bromide is extracted with n-butanol, and isopropanol precipitates out […]
