Storage Conditions | Store at -80°C. The enzyme is stable on ice for 30 to 60 min, but may lose activity with dilution and/or prolonged storage on ice. It is recommended that thawing and addition of the enzyme to assay wells be done within as short a time as possible before start of the assay and that the thawed enzyme be kept on ice throughout. Best performance will be obtained by adding the chilled, undiluted enzyme directly to pre-warmed buffer and proceeding immediately to the addition of pre-warmed substrate. The remaining, unused enzyme should be refrozen quickly by, for example, snap freezing in a dry/ice ethanol bath or liquid nitrogen. The enzyme is stable to at least 4 freeze/thaw cycles. To minimize the number of freeze/thaw cycles, aliquot the HDAC2 into separate tubes before storing at -80°C. |
