AgarACE Agarose-Digesting Enzyme 25u M1741
500u M1743
AgarACE Enzyme is supplied in a storage buffer containing 20mM Tris-HCl (pH 7.3
at 23°C).
Unit Definition: One unit of AgarACE Enzyme completely degrades 200µl
(200mg) of molten 1% Cambrex SeaPlaque ® agarose in 1X TBE (pH 8.3) in
15 minutes at 42–47°C as judged by release of reducing sugars.
Storage Conditions: Store AgarACE Enzyme at –15 to –25°C. AgarACE
Enzyme may be stored at 2–8°C for up to 3 weeks. AgarACE Enzyme is
stable to at least 10 freeze-thaw cycles and is stable at room temperature
(15–30°C) for at least 1 day.

General Considerations
Figure 1 depicts a basic protocol for the digestion of a 1% (w/v) Promega LMP,
Preparative Grade Agarose gel in 1X TAE buffer using AgarACE Enzyme. A
more detailed protocol is described in Section V. If you are using TAE and a 1%
agarose gel prepared from preparative grade LMP agarose, this basic protocol
should be sufficient for your needs. In general, using different buffers or
agarose types will have very little effect on the number of units of AgarACE
Enzyme required. However, the protocol must be modified when non-LMP
agaroses are used (these changes are noted in the protocol in Section V). Using
a different agarose percentage or digestion time effect how much AgarACE
Enzyme is needed. The following subsections provide information on the
amount of enzyme required under various digestion conditions.
