    摘要: A novel process for the preparation of water-soluble acyl glycoprotein extracted from Klebsiella Pneumoniae containing 30 to 45% by weight of proteins, 30 to 40% by weight of neutral saccharides, less than 4% of glucuronic acid, 2 to 5% by weight of osamines with a molecular weight of about 350,000 daltons and having a polysaccharide chain of n chains of one molecule of glucose and 4 molecules of galactose attached to an asparagine of a proteidic chain by a core formed of heptose and 2-keto-3-deoxy-octulosonic acid followed by an acyl portion containing .beta.-hydroxymyristic acid and then N-acetyl-glucosamine designated herein as F.sub.1 and compositions and a method of inducing antiallergic properties in warm-blooded animals.
