Bartonella 26kDa

Source: Escherichia Coli. Sterile Filtered solution. Numerous forms of Bartonellosis are caused by Bartonella henselae as well as Cat Scratch Disease & Bacillary Angiomatosis. It has been found that up to 95% of patients with Cat Scratch Disease show antibodies against Bartonella henselae antigens. Highly immunoreactive proteins which are produced by the Bartonella henselae are the most important antigens used for the diagnosis of Cat Scratch Disease. Bartonella henselae of outer membrane protein p26 has an important nucleotide identity with orthologs in Bartonella spp, Brucella spp in addition to more than a few plant-associated bacteria. Recombinant Bartonella Henselae 26kDa produced in E.Coli is a single, non-glycosylated polypeptide chain having a molecular mass of 25kDa. Bartonella 26kDa is expressed with a -10x His tag at N-terminus and purified by proprietary chromatographic techniques.

Greater than 80% as determined by SDS-PAGE.

Bartonella 26kDa is supplied at a 20mM HEPES buffer pH-7.6, 150mM NaCl and 40% Sucrose (w/v) .

Store at 4°C if entire vial will be used within 2-4 weeks. Store, frozen at -20°C for longer periods of time. Avoid multiple freeze-thaw cycles.
