[DIYbio] Re: first, cheap and effective termal cycler PCR at home

PCR was originally done by setting up three water baths at different temperatures (annealing 55-65C, extension 72C,  denaturation-boiling), and moving the PCR reaction tubes by hand between water baths.  This is the easiest way to test PCR.  Estimate about 2 min total per cycle, in one hour a PCR amplification can be done.  This gets tedious--sitting there, watching a timer--which is why PCR machines were developed, but you can start trying it without building/buying a machine.

Cheers,

Jim Lund

Hello everyone,

I am biology teacher and I discovered this DIYbio movement one week ago, and it is amaizing. I am thinking of buying a thermal cycler for me and maybe then bring it somehow to the school.

I would like to know your opinion about the 2 opensource thermal cycler that I have found:

I have read about this one and it seems it works well.

This is much cheaper and for me would be perfect buy this one, but I know nothing about this one and it seems too simple...

Futher, I would like to ask if you  think it is a bit crazy and if it's going to be too much
expensive the rest of material, primers, buffers,... If I just want to play in my home.

thanks,
