Replica plating is a microbiological technique in which one or more secondary Petri plates containing different solid (agar-based) selective growth media (lacking nutrients or containing chemical growth inhibitors such as antibiotics) are inoculated with the same colonies of microorganisms from a primary plate (or master dish), reproducing the ...
The problem is to find out these phage resistant mutants from within the confluent lawn of cells and to isolate it. This is accomplished by replica plating method. Principle: Using the threads of velvet or chamios leather which act as inoculating needles, the mutants can be replicated and isolated. Requirements: 1.
The replica plating experiment, devised by Joshua and Lederberg in 1952, is a simple process for screening large populations of microbial colonies on culture plates for genetic markers of interest. It has proved useful for discovery of rare auxotrophic mutations, detection and isolation of recombinant organisms after gene transfer procedures ...
Replica plating is an experimental technique that uses a printing-like transfer employing fabric with a pile (e.g., velveteen) to make multiple copies of an original culture plate with each microbial colony identified by its position on the culture plate.
Replica plating provides a rapid screening method for analyzing phenotypes. Colonies on a master plate are transferred to a sterile piece of velveteen. Copies of the mater plate are transferred to additional selective or indicator media to monitor phenotypes under additional conditions.

May 11, 2012 · Replica plating is a method that permits simultaneous screening of a large number of microorganisms. For instance, after mutagenizing a culture of wild-type cells, one can spread-plate dilutions of the culture to obtain plates with single colonies.
The procedure of replica plating technique is as follows; the master plate (mixture of prototroph and auxotroph) will be duplicated to medium with and without leucine by means of rubber stamp like device (called as replica plate).
In molecular biology and microbiology, replica plating is a technique in which one or more secondary Petri plates containing different solid (agar-based) selective growth media (lacking nutrients or containing chemical growth inhibitors such as antibiotics) are inoculated with the same colonies of microorganisms from a primary plate (or master ...
Jun 24, 2024 · Quick Reference. A technique used to produce identical patterns of bacterial colonies on a series of petri plates. A petri plate containing bacterial colonies is inverted, and its surface is pressed against a cylindrical block covered with velveteen.
