To generate the pGLUE tandem-affinity purification plasmid, the pIRES–puro (Clontech, Mountain View, CA) was used as the backbone vector and the dual affinity tag was constructed using PCR.
The pGLUE expression vector was designed to have the streptavidin-(streptag) and calmodulin-(CBP) binding affinity tags placed in tandem at the N-terminus of the bait protein. An HA epitope is also present to facilitate protein detection. The first round of affinity purification is performed using a streptavidin resin, followed by the specific elution with biotin and the protease TEV. The second round is done using the calcium dependent binding to the calmodulin resin and specific elution by chelation using EGTA.
