Method Description

This Borrelia burgdorferi (Lyme) assay is based on a synthetic peptide antigen (C6 peptide) in microwell enzyme-linked immunosorbent assay (ELISA) format. The antigen is derived from the vlsE protein of Borrelia burgdorferi. In the assay procedure, diluted cerebrospinal fluid specimens are added and incubated in wells of an antigen-coated microwell plate. Antibodies specific to the C6 peptide in the specimen are bound by the immobilized antigen, and unbound antibodies are removed by wash steps. The bound antibodies are detected by addition of a horseradish peroxidase-conjugated goat antihuman IgG/IgM conjugate. After removal of excess conjugate by further wash steps, a chromogenic peroxidase substrate containing tetramethylbenzidine is added. A blue-green product is produced in wells where antibodies have been bound to the antigen. The color development reaction is quenched by addition of dilute sulfuric acid, after which optical absorbance at 450 nm is measured in each well using an ELISA plate reader.(Package insert: Immunetics C6 B. burgdorferi [Lyme] ELISA Kit.
