Introduction
Treponema pallidum, a gram-negative spirochaete bacterium, exhibits limited metabolic capabilities due to its adaptation to the nutrient-rich environment of mammalian tissue. This bacterium, known to have at least four subspecies (T. pallidum pallidum, T. pallidum pertenue, T. pallidum carateum, and T. pallidum endemicum), possesses a helical structure enabling corkscrew motion through viscous substances like mucus. Notably, T. pallidum pallidum has a remarkably small genome (1.14 million base pairs) indicative of its reduced metabolic capacity.
Description
This recombinant protein, derived from E. coli, encompasses the immunodominant regions of the outer membrane T.Pallidum p41 protein. It is engineered with a Beta-galactosidase tag for various applications.
Purity
The purity of the Treponema pallidum protein exceeds 90%, as assessed by 10% PAGE (Coomassie staining).
Formulation
The protein is supplied in a buffer containing 10mM Tris-HCl (pH 8.0), 1mM EDTA, 1mM DTT, and 8M urea.
Stability
For optimal stability, T.pallidum p41 should be stored below -18°C. While it can remain stable at 4°C for up to one week, repeated freeze-thaw cycles should be avoided.
Applications
Treponema pallidum serves as a valuable tool for ELISA and Western blot analyses. Its exceptional antigenic properties make it ideal for the specific detection of T. Pallidum, minimizing cross-reactivity issues.
Purification Method
Treponema pallidum protein was purified by proprietary chromatographic technique.
Specificity
Immunoreactive with sera of T.Pallidum infected individuals.
