Concentration:
1 unit/l
Tested User FriendlyTM Functional Test:
Isolation of linearized plasmid from low-melting agarose, > 50% recovery.

Applications:

*
Quantitative recovery of DNA from low-melting point agarose gels.

PROTOCOL FOR RECOVERING FRAGMENTS FROM LOW-MELT AGAROSE

*Equilibrate DNA/agarose in at least 2 volumes of 1X Beta-Agarase Reaction Buffer for approximately 20 min.
*Spin briefly and remove the supernatant.
*Incubate DNA/agarose at 70C for 10 min to melt the agarose.
*Cool to 40C and maintain the temperature at 37C.
*Add an equal volume of 1X Beta-Agarase Reaction Buffer.
*Add one unit of Beta-Agarase for every 50 l of agarose gel. Do not include the volume of the buffer for this determination.
*Incubate the enzyme/DNA/agarose for 1-18 hours at 37C. The treated DNA may be used directly for ligation, restriction digests, etc. or further purified as in steps 8-12.
*Extract once with buffer equilibrated phenol.
*Extract once with buffer equilibrated phenol:chloroform (1:1).
*Extract twice with chloroform:isoamyl alcohol (24:1).
*Add 2 volumes of TE (pH 7.6) to prevent precipitation of the oligosaccharides. Precipitate with 0.05 volumes of NaCl and 2 volumes of 95% ethanol. Incubate at -20C for 30 min, then spin in a microcentrifuge. Wash the pellet twice with 70% ethanol.
*The DNA solution may be used directly for ligation, restriction digests, transformation and sequencing or the purified DNA may be concentrated.
