Description			Treponema pallidum is the causative agent of syphilis. It is a spirochete, a helical to sinusoidal bacterium with outer and cytoplasmic membranes, a thin peptidoglycan layer, and periplasmic flagella. Mechanisms of T. pallidum pathogenesis are poorly understood. No known virulence factors have been identified, and the outer membrane is mostly lipid with a paucity of proteins. Consequently, existing diagnostic tests for syphilus are suboptimal, and no vaccine against T. pallidum is available. TIGR sequenced the genome of T. pallidum subsp. pallidum (strain Nichols) by the whole genome random sequencing method. The T. pallidum genome is a circular chromosome of 1,138,006 base pairs containing a total of 1041 predicted open reading frames. Source: Recombinant protein corresponding to human T. pallidum p47 at N-terminal, expressed in E. coli. Molecular Weight: ~114kD Applications: Suitable for use in ELISA, Western Blot. Other applications not tested. Recommended Dilution: Optimal dilutions to be determined by the researcher. Storage and Stability: Aliquot to avoid repeated freezing and thawing and store at -70°C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap.
