[Mapping of diagnostically important antigenic regions of major outer membrane protein (MOMP) from Chlamydia trachomatis using recombinant proteins with overlapping structures].

ABSTRACT

Amino acid sequence of the Chlamydia trachomatis major outer membrane protein (MOMP) was modeled using a series of the recombinant proteins containing six 100 aa fragments of MOMP overlapped in 30 aa. Testing of recombinant antigens in EIA showed that proteins containing MOMP fragments comprising 191-286 and 191-354 aa regions had the greatest activity in the reaction with anti- C. trachomatis positive serum samples. The data obtained allows the conclusion about the possibility of the use of presented recombinant proteins for development of diagnostic test for anti- C. trachomatis antibodies detection to be made.
