Isolation and partial characterization of a novel basement membrane collagen

R Dixit et al. Biochem Biophys Res Commun. .

Abstract

A guanidine-HCl extraction of lens capsule basement membrane dissolves collagenous material. This material was fractionated on an Agarose A-5M column. Fractions 1, 2 and 3 were further purified and partially characterized immunochemically and by amino acid analysis. Fraction 3 has a molecular weight of 55,000 when compared with collagen type I standard. The CNBr peptide pattern and composition of fraction 3 are different from those of alpha 1 (IV) 95K and alpha 2 (IV) 95K chains. The results described suggest the presence of a new chain in lens capsule basement membrane.
