I want to amplify a RNA product from a single cell and I try to get more yield. I want to use the LAMP method but I haven't bought any software yet. I only try to design primer by myself.
Actually you can use the free software available on the net. Try this link
primerexplorer.jp/e/ . I've tried to design primers using this software, but the length of your gene of interest need to be long enough,but not too long, for the software to generate primer for you.
However, you might need to further analyse the primer and suggested to order a few sets, because some of the primer might not work.
