Immuno- and histochemical studies on galactan and human blood group-related receptors in the bovine lung.

Using a monoclonal anti-galactan antibody and streptococcus B type II antibody, the distribution of lung galactan could be demonstrated for the first time in a vertebrate organ. In addition to the immunochemical demonstration of the bovine lung galactan, a human blood group A-like glycoprotein is detectable by lectinological methods in the bovine lung tissue. Various other lectin-receptors, for instance those of the peanut lectin (PNA) or for lectins with L-fucose (UEA) and N-acetyl-lactosamine (ECA) specificity show a typical staining pattern in bovine lung.
