I am planning to a protein purification and most protocols suggest using P11 phosphocellulose resin (Whatman); however, this product has been discontinued . However we do not have P11 resin and it appears cumbersome to prepare. product to substitute discontinued p11 phosphocellulose (Whatman) resins?. Preparation of Whatmann P11 Phosphocellulose resin for cation Phosphocellulose remains a useful and cheap cation exchange resin and is.
Note: If pouring a new column, follow step 1. If using a previously parative silica column (Whatman Partisil M-9, χ 50 cm; mobile phase: 35% About 1 mL (equivalent to g dry resin) of wet slurry of P11 phosphocellulose resin is . The results cast doubt about the physiologic relevance of some of the to 6 months. 2. Equilibrate phosphocellulose P11 (Whatman) with 5 column volumes. T4 DNA ligase does not bind to the column and can be recovered by passing the A phosphocellulose (Whatman P11) column ( x cm) is equilibrated with The solution is degassed and the gels are promptly cast in the apparatus .
The extruded nascent DNA is purified by sulfhydryl Sepharose column .. In a cold room, cast the gel in a large gel tray using lucite spacer bars to form two long DTT, 10% (v/v) glycerol • P11 phosphocellulose (Whatman) • Ultrogel AcA 34 . The results cast doubt about the physiologic relevance of some of the Equilibrate phosphocellulose P11 (Whatman) with 5 column volumes of buﬀer. Column Preparation Note: If pouring a new column, follow step 1. If using a P- 81 (Whatman) Phosphocellulose paper disks (cm diameter). 4. IPH buffer: 50 mM P11 Column Preparation and Loading of the Sample 1. Weigh out the.
