Detection of urinary glycoprotein GP 41 in leukemic patients and in healthy donors.

Urinary glycoprotein patterns from leukemic patients and from healthy donors were found to be identical, when the detection was carried out with the same quantities of protein. Two dimensional polyacrylamide gel electrophoresis revealed seven independent glycoproteins in the molecular weight region of 41,000 dalton, regardless of the origin of the urine, indicating, that these glycoproteins do not reflect any specificity of cytoreduction in the course of chemotherapy.
