METHOD OF HUMAN BIOPSY MATERIAL AND EXCRETE ANALYSIS FOR CHITINASE-LIKE PROTEIN YKL-40 Russian patent published in 2011 - IPC G01N33/53 

FIELD: medicine.

SUBSTANCE: method of quantitative determination of human chitinase-like protein YKL-40 (another name - human cartilaginous glycoprotein-39, or HcGP-39) is offered. When implementing the method, colloidal chitin or heparin is sorbed in microplate wells, then solutions containing a certain amount of chitinase-like protein, and analysed samples are introduced in the wells. The amount of YKL-40 is analysed by the amount of an enzymatic reaction product formed by interaction of an enzymatic conjugate with YKL-40 antibodies against with a substratum of this enzyme.

EFFECT: method allows well reproducible and high sensitive YKL-40 analysis in various human biopsy materials and excretes.
