Amplification: Protocols and Information
Amplification

Amplification

Learning to manipulate the number of phage on a plate is an important part of the phagehunting process. Making a high titer lysate of your phage is an essential part of success of your project. Correct amplification process ALWAYS begins with picking a single isolated plaque. In particular, when making lysates of phages with a predictable clear plaque mutant, making lysates from lysates can distort the proportion of those mutants.

How many phage particles do you need to obtain maximum yield for your high titer lysates? It is an empirical investigation, but remember to do the math! This explanation shows data for a large, medium and small plaque forming phage.
