Abstract
The presently claimed and described technology is directed to an acidic high polymer composition comprising about 1.0% (w/v) polymer and about 4% (v/v) carboxylic acid. The acid high polymer composition may be used as a neutral capillary storage or conditioning solution or in a method of improving capillary isoelectric focusing (cIEF) robustness or performance. The technology is also directed to a kit comprising an acidic high polymer composition, at least one stabilizer, an anolyte, and a catholyte.
