title: Size and domain structure of collagen VI produced by cultured fibroblasts.
abstract: Disulfide-bonded forms of collagen VI were analyzed by immunoblotting of fibroblast culture medium and cell extracts. The protein consists of pepsin and collagenase-resistant domains of about equal size indicating a molecular mass of 340 kDa for collagen VI monomers.
