Isolation of thymus gland fractions and the determination of their biological activity
A calf thymus extract was prepared and fractionated into lipid and non-lipid fractions. The non-lipid fraction was isolated from the calf thymus extract using the Folch method. The components isolated from the non-lipid fraction were characterized by IR, NMR, biuret and HPLC method. The results of t...

| Summary: | A calf thymus extract was prepared and fractionated into lipid and non-lipid fractions. The non-lipid fraction was isolated from the calf thymus extract using the Folch method. The components isolated from the non-lipid fraction were characterized by IR, NMR, biuret and HPLC method. The results of the analyses indicated the presence of peptides. The lipid fraction contained phospholipids, glycolipids and neutral lipids. The biological activity of both the isolated lipid and peptide fractions was determined by the in vivo hemolytic plaques method in Wistar rats with an involuted thymus. The peptide and phospholipid fractions of the thymus extract showed a significant increase of hemolytic plaques. The glycolipid and neutral lipid fraction failed to express a significant immunological response. |
