Invitrogen™ Anza™ 23 PstI is a restriction enzyme that cuts DNA at this recognition site: CTGCA^G, completely digesting the DNA in 15 minutes at 37°C.

For superior convenience, a single buffer and protocol are used with all Anza™ restriction enzymes. The single Anza buffer allows multiple restriction enzymes to be used simultaneously in one reaction. This helps eliminate the need for sequential digests and the DNA clean-up necessary when changing buffers. Additionally, the Anza buffer and restriction enzymes have been designed for flexibility in digestion times. Digestions of up to 16 hours can be carried out without star activity.

• Convenient—all Anza enzymes are 100% functional in the single Anza buffer
• Fast—complete digestion in 15 minutes
• Flexible—overnight digestion without star activity
• Simple—a single digestion protocol for all DNA types
• Complete system—incorporates Anza DNA Modifying Enzymes for a complete cloning experience

Anza DNA Modifying Enzymes include the Anza T4 DNA Ligase Master Mix, Anza Alkaline Phosphatase Kit, Anza T4 PNK Kit, Anza DNA Blunt End Kit, and Anza DNA End Repair Kit. Use these enzymes for a complete cloning workflow.

Anza Red Buffer, which contains a density gradient and tracking dyes, is supplied for added convenience. Digestion reactions are as efficient in the Anza Red Buffer as in the Anza Buffer. Use of the Anza Red Buffer helps reduce pipetting steps when preparing multiple digestion reactions and a subsequent step includes agarose gel electrophoresis. For applications that require product analysis by fluorescence excitation, the colorless Anza Buffer without the tracking dyes is recommended.
