HOOK™ GST Protein Purification (Yeast)
HOOK™ GST Protein Spin Purification kit allows for the rapid purification of soluble, GST tagged protein from
yeast cultures. The yeast are first lysed with Yeast PE LB™ and LongLifeTM Zymolyase® to release total
soluble protein, whilst maintaining the structure and activity of the protein. The GST tagged protein is purified
by passing the clarified lysate through prepacked columns.
Yeast-PE LB™ is useful for extraction of soluble proteins from yeast cells. Yeast PE LB™ is a proprietary
improvement on the Zymolyase® based spheroplast preparation and extraction of soluble proteins from
yeast cells. Yeast PE LB™ is based on organic buffering agents that utilize a mild non-ionic detergent and a
proprietary combination of various salts and agents to enhance extraction and stability ofproteins. A ready-
to-use Zymolyase® preparation is also provided. Depending on application, additional agents such as
protease inhibitors may be added into Yeast PE LB™. The proprietary combination of this reagent provides a
simple and versatile method of yeast protein extraction. Yeast PE LB™ eliminates the need for laborious
glass bead lysis of yeast cells.
HOOK™ GST Protein Spin Purification kit is optimized to yield up to 10mg of soluble GST tagged protein, with
a purity of 80-90%, dependent on expression levels, resin type, conformation and solubility characteristics of
