Sep September 13, 2011 | 15 Comments Polymerase chain reaction is a molecular biology technique in which small amounts of DNA can be amplified exponentially to generate millions of copies in a test tube.

When this technique was invented by Kary Mullis in 1983, it was revolutionary — so much that he received the 1993 Noble Prize in Medicine. Since then, PCR has become an absolute requirement for most biological sciences and is widely used for many applications (e.g., forensic analysis, paternity testing, basic research, drug discovery, blood screening, etc). The different steps of each PCR cycle must occur at different temperatures ranging from 200 degrees ( denaturation ) to 39 degrees Fahrenheit (final hold).

Classically, this was done using water baths of different temperatures, but this was a very tedious process since water bath transfer was done manually. To solve this problem, the thermal cycler was invented. Traditionally, thermal cyclers tend to be on the expensive side. THE MACGYVER PROJECT: GENOMIC DNA EXTRACTION AND GEL ELECTROPHORESIS EXPERIMENTS USING EVERYDAY MATERIALS. Abstract:DNA extraction and separation by agarose gel electrophoresis is a simple and exciting process that anyone can perform. However, the high cost of specialized equipment and chemicals often hinder such an experiment from being carried by members of the high school community.

Here, we describe a cost effective way of extracting and electrophoresing DNA under a prescribed MacGyver limitation – that is using only materials available from a grocery store or shopping mall. In order to carry out this project, we decided to first divide the procedure into three specific sections, each to be addressed individually. Doing this, you find that the following challenges are present. Extraction of DNA in a Research Setting: In a conventional research setting, the first step in extracting DNA involves breaking open the cell’s membrane by using physical or chemical means.

A genomic prep is also interesting from an educational point of view. A: “Saline Buffer”0.9% saline (contact lens solution) Arduino PCR (thermal cycler) for under $85. This tutorial will show you how to make a thermal cycler from scratch for about $85. In short, PCR (polymerase chain reaction) amplifies bits of DNA, creating millions of copies of a target sequence. You can use it to test a DNA sample for a specific gene, for instance, to check for genetic modification in food and for hereditary gene testing.

During PCR, a mixture of DNA, primer and DNA polymerase is cycled between three different temperature settings, over and over again. This project uses an arduino to control two high-power resistors to heat up the sample, a computer fan to cool down, and a thermocouple to keep track of the temperature. The design supports two samples at a time, though it could probably be extended to support more. The parts are all off-the shelf, and the assembly should take a few hours. This project is still a work in progress by Stacey Kuznetsov ( and Matt Mancuso ( LavaAmp: cheapest pocket PCR thermocycler dreamed for DIY biologists « Pimm – Partial immortalization.

The LavaAmp is a portable PCR thermocycler that has the potential to become the default garage biology (home biology, bioDIY, DIYbio) tool once it hits the market. Think of Apple II for personal computing or MakerBot for 3D printing. The 1st LavaAmp prototype was shipped this week from Biodesic to Gahaga Biosciences and the process is documented and engineering details uncovered in Rob Carlson’s post. The people behind are mainly ex SciFoo Campers and open science advocates: Guido Nunez-Mujica, Joseph Jackson, Rob Carlson, Jim Hardy and a cool engineer Rik Wehbring. Here’s the pic of the prototype: In the 2007 proof-of-concept paper, entitled A Pocket-Sized Convective PCR Thermocycler, authors Nitin Agrawal, Yassin A.

Herein, we introduce an innovative thermocycling system that harnesses natural convection phenomena to amplify DNA rapidly by the PCR in a greatly simplified format. The intended initial customers are hobbyists and schools. Like this: Like Loading... Build it | OpenPCR - Open source, hackable, personal PCR machine. OpenPCR takes about 3 hours to build.
