I need some TRIZOL - (Oct/27/2001 )

Hi,Everyboday,I try to conduct some RNA research recently.And I need some TRIZOL,however the TRIZOL from many Companies are too expensive,so could you tell me how to prepare it by myself?

besides ,how can i make high competen cells using one step?Thanks

TriReagent is available from Sigma. Sigma has good prices in my opinion, not as high as some other companies, and they have good delivery.
