CirclegrowT Powder 454g

CIRCLEGROW® is used for growth of E.coli and extends plasmid production past log phase. Molecular Biology Certified™ Obtain rapid growth of E.coli High yields of plasmid DNA At the end of log phase, cells growing in Circlegrow begin to utilize a proprietary second carbon source that becomes available on a delayed basis. Cell growth and plasmid replication continue long after cells in conventional media have reached stationary phase or expired. Bacteria commonly grow in Circlegrow to a density triple that achieved in other media. The slow post-log phase growth of bacteria in Circlegrow eliminates the need for constant OD monitoring. Circlegrow cultures left overnight or over the weekend will have a much lower percentage of dead cells, and a higher percentage of plasmid DNA, than cultures prepared with any other media. The result is a higher yield of plasmid DNA in less volume with less attention.
