title: Rapid semi-quantitative isolation of beta-2-microglobulin from urine.
abstract: A rapid semi-quantitative purification of beta 2-microglobulin from transplant urine relies on a batch absorption using hydroxylapatite-cellulose. Stepwise elution is followed by Sephadex G-150 gel permeation chromatography. Using this methodology, it is possible to process quickly and conveniently many liters of urine at bench scale, with yields exceeding 95% and overall purity greater than 97% beta 2-microglobulin.
