HeLaScribe Nuclear Extract in vitro Transcription System

by Promega
€ 550.08

The most well characterized cell-free system for in vitro transcription of eukaryotic genes is derived from HeLa cell nuclei. HeLa nuclear extracts can support accurate transcription initiation by RNA polymerase II and exhibit both basal and regulated patterns of RNA polymerase transcription. The nuclear extract is also a source for a variety of transcription factors, DNA-binding proteins and the enzymatic machinery involved in RNA processing. The HeLa Nuclear Extract included in the HeLaScribe Nuclear Extract in vitro Transcription System is prepared by a method that has been shown to allow transcription from the human transferrin gene promoter and the adenovirus 2 major late promoter. The system includes all of the necessary components for in vitro transcription as well as a positive control template (CMV immediate early promoter DNA).
