HIT™-Blue are unique chemically competent cells, which utilise a novel transformation protocol-High Ice Transformation. A simple ice incubation from 1-10 minutes is all that is required to transform the cells to high efficiency. There is no requirement for heat shock or recovery step.
Efficiency Levels
Each HIT™ shipment is -70°C electronically monitored and recorded for minimum efficiency guarantee.
