The MagneSil system can selectively isolate PCR products that are more than 150-bp long from primers and primer -dimers. The technology can be used with a number of robotic workstations, including Beckman Coulter’s Biomek 2000 and FX Laboratory Automation Workstations. The procedure can also be carried out manually. Typical recovery is more than 80% for a 1-kb product with negligible carryover of primers or nucleotides. - [Read A Magnetic Particle-Based Method for Purifying PCR Products from Solution Protocol]

Two methods are provided for purifying glycoproteins using wheat-germ agglutinin or concanavalin A-Sepharose. Because lectin-affinity matrices can bind a few milligrams of protein per milliliter of affinity matrix, only a small amount of affinity gel matrix is required. The batchwise method is recommended when protein volume is large. - [Read Lectin-Agarose Affinity Chromatography Protocol]

Intermediate filaments (IF) are major cytoskeletal systems of vertebrate and many nonvertebrate cells whose expression is cell-type specific and developmentally regulated. This protocol describes a method for purifying one type of IF, vimentin, from bovine lens tissue. Purification of human vimentin expressed in Escherichia coli is also described. These methods are useful in the preparation of other IF protein subunits for microinjection studies as well. - [Read Purification of Bovine Lens and Bacterially Expressed Human Vimentin Protocol]
