using a monoclonal anti-tubular basement membrane antibody ( alpha tbm-ab ) affinity column , we isolated from collagenase-solubilized human renal tissue ( hsrta ) a predominantly 48,000-mol-wt moiety ( h3m-1 ) which is selectively recognized by antisera from two patients with alpha tbm-ab-associated interstitial nephritis ( alpha tbm disease ) .
