Distribution and isolation of four laminin variants; tissue restricted distribution of heterotrimers assembled from five different subunits.

Abstract excerpt

The distribution of subunits of the basement membrane proteins laminin and merosin in human and rabbit tissue was studied by immunofluorescence using monoclonal antibodies. The laminin A chain is present in epithelial, endothelial, and smooth muscle basement membranes. Merosin, as defined by its heavy chain M, is present in striated muscle and peripheral nerve. The A subunit colocalizes with at least two B...
