Source:<\/strong> An E.coli strain that carries the cloned Apa I gene from Acetobacter pasteurianus
\nUnit definition:<\/strong>
\nOne unit of the enzyme is the amount required to hydrolyze 1 \u03bcg of Lambda DNA (dam-dcm-, BamHI-digest) in 1 hour at 37\u00b0C in a total reaction volume of 50 \u03bcl.

Storage conditions<\/strong>: 10 mM Tris-HCl (pH 7.5); 200 mM NaCl; 0.1 mM EDTA; 7 mM 2-mercaptoethanol; 200 \u03bcg\/ml BSA; 50% glycerol. Store at -20\u00b0C.
\nLigations<\/strong>:
\nAfter 20-fold overdigestion with enzyme > 95% of the DNA fragments can be ligated and recut.
\nNon-specific hydrolisis<\/strong>:
\nNo nonspecific activity was detected after incubation of 1 \u03bcg of Lambda DNA with 40 u.a. of enzyme for 16 hours at 37\u00b0C.Reagents Supplied with Enzyme<\/b><\/p>\n
