Interferons

Interferons are the antiviral proteins that inhibit both the transcription and translation of the viral genome. It was first studied by the two scientists named Isaac and Lindenmann in the year 1957, while they experimented on the chick chorioallantoic membrane fragments with the live influenza virus. On experiment, Isaac and Lindenmann found that the interaction …

Micropropagation Technique

The micropropagation technique is an in-vitro plant tissue culture method that can prepare many clones from the small tissue of the stock plant. It is now the most preferred method over the traditional techniques of vegetative propagation. A botanist Frederick Campion Steward first introduced the process of micropropagation. Micropropagation also gives rise to genetically modified plants …

Difference Between Agarose and Polyacrylamide Gel

The difference between agarose and polyacrylamide gel relies upon factors like origin and molecular complexity. Both gels help in biomolecular separation, due to their porous nature. We can separate, identify and purify different biomolecules using agarose and polyacrylamide gels. 1. Origin: Agarose is a natural polymer extracted from several red seaweeds. So, it is a …
