USING MONOCLONAL ANTIBODIES FOR IDENTIFYING YAMAGATA OR VICTORIAN INFLUENZA B VIRAL EVOLUTION LINE, HYBRIDOMA 4H7 STRAIN FOR PREPARING MONOCLONAL ANTIBODIES USED TO IDENTIFY INFLUENZA B VIRUSES IN YAMAGATA BRANCH, HYBRIDOMA B/4H1 STRAIN FOR PREPARING MONOCLONAL ANTIBODIES USED TO IDENTIFY INFLUENZA B VIRUSES IN VICTORIAN BRANCH Russian patent published in 2013 - IPC C12N5/18 C07K16/08 G01N33/531 

FIELD: medicine, pharmaceutics.

SUBSTANCE: invention discloses using the monoclonal antibodies (MCAs) produced by the hybridomas B/4H1 and 4H7 and directed to variable determinants as a part of influenza B virus proteins. The hybridoma B/4H1 and 4H7 strains are deposited in the Russian Collection of Vertebral Cell Cultures (RKKK P) under Nos. 719 D and 720 D, respectively. The two current influenza B viral evolution lines are identified with using the MCAs B/4H1 and MCAs 4H7 directed to variable determinants of Victorian-type and Yamagata-type influenza B hemagglutinin, respectively.

EFFECT: using the prepared MCA kit enables identifying the newly recovered influenza B viruses Besides, the MCAs under the invention may be used to study the antigenic structure and variability of this agent, to identify them as belonging to a specific evolution line; the MCAs may be also used to construct the diagnostic test systems.
