Borrelia is a part of the genus of bacteria of the spirochete phylum. Borrelia causes borreliosis, which is a zoonotic, vector-borne disease transmitted mainly by ticks and some by lice, depending on the species. Of the 36 known species of Borrelia, 12 are distinguished to cause Lyme disease or borreliosis and are transmitted by ticks. The main Borrelia species causing Lyme disease are Borrelia burgdorferi, Borrelia afzelii, and Borrelia garinii. Variable major protein like sequence E1 protein (VlsE1) is a borrelial surface protein which is the most sensitive protein for IgG antibody detection in all stages of Lyme disease.
Recombinant Borrelia VisE1 (variable major protein like sequence E1) produced in E.coli is a non-glycosylated, polypeptide chain having a calculated molecular mass of 43kDa.
Borrelia VisE1 is expressed with a -10x His tag at N-terminus and purified by proprietary chromatographic techniques.
Borrelia VisE1 is supplied in 20mM HEPES buffer pH-8.0, 200mM NaCl and 20% glycerol.
Avoid multiple freeze-thaw cycles.
Greater than 95.0% as determined by SDS-PAGE.
Western blot with Patient sample.
1. Binds IgG- and IgM-type human antibodies.
2.Immunodot test with Lyme disease positive/negative samples.
