Claims11
An immunostimulating glycopeptide suitable for use in conferring on mammals or birds a resistance to Sarcoma 180T/G tumour and pathogenic microoganisms which glycopeptide is obtainable from the cell wall of an immunostimulating bacterium belonging to the Actinomycetaceae family of Prevot's classification, which glycopeptide is substantially insoluble in water, physiological saline, methanol, ethanol, phenol, chloroform, dioxan, pyridine, dimethylformamide, diethylene glycol, and hexane;
- has an absorption in the Infra-red spectrum at 1550 and 1660 cm.sup.-1 consistent with the presence of peptide;
- has an absorption in the Infra-red spectrum between 950 and 1100 cm.sup.-1 with a maximum absorption at 1050 to 1070 cm.sup.-1 consistent with the presence of carbohydrate;
- has little or no lipid absorption in the Infra-red spectrum at 2850 to 2950 cm.sup.-1 ;
- and which glycopeptide, after intravenous administration, increases the liver and spleen weight of mice, and increases the life expectancy of mice with tumours,
