Fai I

Source: Flavobacterium aquatile B15

 

5000 – 1000 u/ml Store at -20°C

Recognition Sequence:
YATR

RTAY

Source: Flavobacterium aquatile B15
Fai I cleaves 4 expected recognition sites as well as several other sites with a weaker activity.In the case of long incubation with Fai I DNA can be digested to small oligos.

 

Supplied in: 10 mM Tris-HCl (pH 7.5); 100 mM KCl; 0,1 mM EDTA; 200 µg/ml BSA; 7 mM  2-mercaptoethanol; 50% glycerol.

Reaction Conditions:

1X SEBuffer B.

Incubate at 50°C.

Warranty period for the enzyme storage at -20˚C is two years from the date of the last assay indicated on the enzyme vial.

1X SEBuffer B  (pH 7.6 @ 25ºC)

10 mM Tris-HCl, 10 mM MgCl2,1 mM DTT

Unit Definition: One unit is defined as the amount of enzyme required to cleave 1 pmol of the double stranded oligonucleotide with the following structure

5′-CGAGTTCA^TAGCTGGGCCCAAC-3′

3′-GCTCAAGT^ATCGACCCGGGTTG-5′

in 1 hour at 50°C in a total reaction volume of 20 μl.

Quality Control Assays

Ligation: After 3-fold overdigestion with Fai I, ~50% of pUC19 DNA fragments can be ligated with T4 DNA Ligase and recut.

Oligonucleotide Assay: No detectable degradation of a single- and double-stranded oligonucleotide was observed after incubation with 1 unit of enzyme for 3 hours.
