One gram E. coli cell paste can produce up to 10 mg PAT protein. 6 mg PAT protein. You can proportionally scale up or down according to the amount of cell extract/lysate you start with. 7. This chromatography can easily be conducted using gravity flow. You also can use a glass column with column adaptor and pump. 8. If the flow rate is too slow, you can resuspend the agarose resin by inverting the capped column a couple of times and then allowing the buffer to drain. 9. Each aliquot of protein is mixed with 5Â SDS loading buffer to a final concentration of 1Â SDS loading buffer, and heated at 95 C for 5 min.

8. Apply ~ 3 BV of elution buffer to the plugged column and cap the column. Mix the agarose with the elution buffer by inverting the capped column. Incubate the agarose in elution buffer for at least 10 min at 4 C. 9. Remove the column’s plug and cap. Allow the PAT-containing elution to drain into a collection tube. Store the elution at 4 C. Save a small sample for SDS-PAGE analysis. 10. Analyze collected fractions from above steps by SDS-PAGE (see Note 9). Load 10 μl of each sample on SDS-PAGE gel (Fig.
