Glycoprotein biosynthesis by organ cultures of hamster trachea.


Conditions have been developed for maintaining hamster tracheas in organ culture for at least 10 days. Secreted glycoproteins labelled with [14C]glucosamine and [3H]fucose were isolated from the spent medium and digested with papain, and the digest was fractionated on DEAE-Sephadex by stepwise elution with NaCl. The fractions eluted by 0.1 and 0.2 M NaCl… (More)
