Figure 1. SDS-PAGE of the C. trachomatis native MOMP from serovar F.
Lane 1) Molecular weight (MW) standards; Lane 2) The Ct-F-nMOMP preparation was not boiled before loading. The major Ct-F-nMOMP band migrated with an apparent MW of 66 kDa corresponding to the native trimer, and the minor band (MW of 40 KDa) indicative of the MOMP monomer; Lane 3) The sample was boiled before loading into the gel. The MOMP migrated with a MW of 40 kDa corresponding to the monomer.
