Single-use One Shot aliquots for unparalleled convenience

The single-use One Shot Kits offer the highest level of convenience

The single-use One Shot kits offer the highest level of convenience

The unique format provides 50 μl aliquots of chemically competent cells in single-use tubes. Transformation is performed directly in the tube, saving you time and effort. There are no extra pipetting steps, no extra tubes, and no loss of efficiency due to repeated freeze-thaw cycles. These kits come with SOC medium and pUC19 positive control.
