Promega offers a variety of cloning enzymes including DNA and RNA ligases and polymerases. T7, T3, and SP6 RNA Polymerases are popular choices for in vitro transcription, as they are highly specific for their respective promoters, and produce high-quality transcripts that can later be used as templates for in vitro translation.

DNA modifying enzymes such as phosphatases, nucleases, and polynucleotide kinase are also available. In addition, we provide radiolabeling systems for linear DNA templates, and PCR and sequencing primers for sequencing inserts that have been cloned into various vectors.
