Abstract

An agarose gel column filtration method has been developed to quantitate labeled mucous glycoprotein secreted into culture medium by explants of tracheal epithelium. A multichannel pump is employed to simultaneously analyze 15 samples. Compared to other methods, such as dialysis and trichloroacetic acid/phosphotungstic acid precipitation methods, the column method not only quantitates high-molecular-weight mucous glycoprotein specifically but also offers the advantages of rapid processing of samples, low-background radioactivity, linearity and reproducibility even with small amounts of labeled mucous glycoproteins, and recovery of samples for chemical analysis. This method can be used to quantitate any substances that can be isolated by a one-step column chromatographic technique.
