摘要：

The large subunit of Na,K-ATPase purified from eel electroplax was found to contain amino sugars, neutral sugars and sialic acid. The concentration of these carbohydrates in the large subunit was 5-10% of that found in the smaller subunit and in total accounts for 2.6% of the mass of the large subunit. The periodic acid-Schiff's stain for glycoproteins on polyacrylamide gels is apparently not sufficiently sensitive to detect glycoproteins with these low levels of carbohydrates. © 1979.
