Extracts have been quality control tested by Western blot and the Electrophoretic Mobility Shift Assay (EMSA).
To ensure stability, we recommend aliquoting the extracts into single-use fractions and then storing them at -80ºC.
Shipped on dry ice. Upon delivery aliquot and store at -80ºC. Avoid freeze / thaw cycles.
