Ion exchange chromatography
Lyophilized from 16 mM NaHCO3, containing 0.05% CHAPS and 0.05% Tween 20.
It is recommended to reconstitute this product with deionized water to its initial concentration.
Lyophilized and reconstituted at -70°C (-65 … -80 °C allowed)
Avoid repeated freezing and thawing. It is recommended to aliquot the product after reconstitution.
The storage of lyophilized protein at -20°C may lead to a loss of 20% of immunochemical activity over two years.
For protein dilutions, we do not recommend PBS or other buffers with high ionic strength. This may lead to precipitation.
This product is sold for research or further manufacturing use only. Standard Laboratory Practices should be followed when handling this material.
