A glycoprotein was extracted from Chlorella vulgaris BEYERINCK and purified by gel filtration on Sephadex G-150. Its molecular weight was 1.21×105 and the composition ratio of sugar and protein was 1 : 1 (w/w). The content of α-helical structure was determined as 18.9% by CD. It was found to have an antitumor activity against sarcoma 180 implanted in mice and also against mouse lymphemia L-1210/v/c in culture.
