Im using mMESSAGE mMACHINE T7 ULTRA Transcription Kit to transcribe my DNA. It produced 30 ng/ul which is 750 ng although the kit promises to yield atleast 15-20 ug of RNA. Even the control DNA provided in the kit produced 6.2 ug RNA. I followed the protocol as it was instructed. Kindly share tips to increase the yield upto 10 ug atleast. TIA!
