fragment (AA 1-200) is
produced from a
E. coli expression system, purified from freshly extracted
cell lysates, and purified to homogeneity using methods developed by LAE
Biotechnology Co., LTD. The final fraction of
contains a single polypeptide band of
50 kDa in a concentration of 0.5 ug/ul and is devoid of contaminating nuclease activity.
In PBS buffer with 20% glycerol.
In general the
is less stable when diluted. We recommend that you
not dilute the enzyme before storage at -70 C. In addition, it is a good
practice to aliquot the enzyme after the first thaw.
The enzyme is shipped on
ice and must be stored at -20 degree or lower.
