Cloning, Expression and Purification of Truncated Chlamydia Trachomatis Outer Membrane Protein 2 (Omp2) and its Application in an ELISA Assay
Background: Although a simple and direct method does not exist for the detection of chlamydial infections, there are situations in which reliable serological tests, with sensi-tivity related to a specific antigen, could be helpful. Objective: The aim of this study was to clone the first 1100 bp of the C. trachomatis outer membrane protein 2 (omp2) gene in order to prepare a recombinant protein ...
متن کاملPartial amino acid sequence and molecular cloning of the encoding gene for the major outer membrane protein of Chlamydia trachomatis.
The first 25 N-terminal amino acids of the major outer membrane protein of Chlamydia trachomatis serovar L2 were determined. The amino acid sequence was used to construct an oligonucleotide probe specific for the major outer membrane protein gene. Using this oligonucleotide as a hybridization major outer membrane protein gene. Using this oligonucleotide as a hybridization probe, we discovered o...
متن کاملOverexpression and surface localization of the Chlamydia trachomatis major outer membrane protein in Escherichia coli.
The Chlamydia trachomatis major outer membrane protein (MOMP) is the quantitatively predominant surface protein which has important functional, structural and antigenic properties. We have cloned and overexpressed the MOMP in Escherichia coli. The MOMP is surface exposed in C. trachomatis and capable of eliciting protective antibodies in infected hosts, and therefore has potential as a candidat...
متن کاملAntigenic analysis of the major outer membrane protein of Chlamydia trachomatis with murine monoclonal antibodies.
We prepared monoclonal antibodies against prototype strains of the 15 serovars of Chlamydia trachomatis and identified a subset of reagents that reacted with the major outer membrane protein(s) (MOMPs) of one or more serovars. We then determined the specificities of these anti-MOMP monoclonal antibodies by radioimmunoassay and immunoblot assays against the 15 serovars of C. trachomatis and a C....
متن کاملMolecular cloning of the major outer membrane protein of Chlamydia trachomatis.
A gene library of Chlamydia trachomatis (serovar L1) DNA has been prepared in the phage vector lambda 1059. From this bank, 20 recombinant phage-expressing components which reacted with serum from a patient with a C. trachomatis (L1) infection were chosen. Selective expression and radiolabeling of phage polypeptides in irradiated Escherichia coli demonstrated that one of these clones encoded a ...
