U
Supplied with
its own unique reaction buffer that is different from the four standard
NEBuffers. Its compatibility with the four standard NEBuffers is indicated
by the chart.
BSA
Supplied
with a separate vial of bovine serum albumin (10 mg/ml). To obtain
100% activity BSA should be added to the 1X reaction mix to a final
concentration of 100 µg/ml.
SAM
Supplied
with a separate vial of S-adenosyl-methionine (SAM). To obtain 100%
activity, SAM should be added to the 1X reaction mix as specified
on the product data card.
dd
When performing
a double digest with this enzyme, this NEBuffer is recommended because
it minimizes star activity.
*
Purified by scientists at SibEnzyme and
supplied with a SibEnzyme buffer (B, K, O, W or Y) which ensures 100%
activity. Its compatibility with the NEBuffer System is indicated
on the chart.
NR
This buffer
is not recommended for use with with this enzyme.
