      no they use an IVT reaction and no cell production

    Is it needed to lyse the cells with lysis buffer? My protein is a cytosolic protein. Thanks!

    Hi, adding enhancers 24 hours after transfection also works? Or does it have to be within 18 hours?

      I know science can seem spooky sometimes, but can you pls explain to me why you think expressing proteins using cells is satanic? I'm baffled lmao

    Add diluted ExpiFectamin TO diluted DNA??? The protocol says "Add diluted DNA to diluted Expifectamine."

      We apologize for the delay in response. Typically, we add diluted transfection reagent to diluted DNA, but both methods will work and give comparable results. Thanks for your question.
