HIT™-JM109 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.
HIT™ Value 108-JM109:
Minimum efficiency is 1 x 107 transformants/μg pUC19

Applications and Genotype
The HIT™-JM109 strain allows blue-white color screening for recombinant lasmids and is an excellent host strain for routine cloning application using plasmid or lambda vectors.
Transform at 9am, pick at 5 pm!
Due to the rapid growth of this strain, HIT™ transformation and picking of colonies may be achieved in one day, potentially eliminating one day from the work schedule.
