Preparation of polyclonal antibodies against pig trachea apomucin
Purified procine tracheal mucin (PTM) was deglycosylated by treatment with trifluoromethanesulfonic acid (TFMS). A preferrential release of fucose, galactose > GlcNAc > GalNAc was observed during the deglycosylation. After five hours of TFMS treatment at 5C, over 90% of the carbohydrate was released leaving mainly Ga1NAc attached to the core protein. The residual Ga1NAc was further removed by three series of the Smith Degradation. The resulting apomucin consisted mainly of (mol %) Thr, 14; Ser, 12; Gly, 12; Glx, 10; Ala, 9; Pro, 8; Val, 7; Asx, 7. Sugars were not detected by gas chromatography. Antibodies obtained by immunizing rabbits with the apomucin recognized only the apomucin and not the holomucin in a double-sandwich ELISA assay. The ELISA is highly specific and has detection limits in the ng range. This antibody preparation was used in precipitation assays of cell-free translation products of pig trachea epithelium RNAs. Translocation products labeled with (TH)Ser and (TH)Thr showed significantly higher counts than with control serum.
