murine MAb against OspB Borrelia burgdorferi, Clone LA-25.1
Description
Borrelia burgdorferi outer surface protein OspB is expressed by spirochetes in the Ixodes scapularis gut. ospB is transcribed from a bicistronic operon with ospA, a known spirochete adhesion gene in the tick gut (1). Several reports, however, have indicated that OspB is present on the surface of B. burgdorferi within unfed ticks (2). Certain OspB antibodies, either as whole immunoglobulin G (IgG) or as Fab fragments, can be bactericidal in vitro, and studies have demonstrated that vaccination with OspB can protect mice from B. burgdorferi infection (3,4,5).
Preparation
The monoclonal antibody ADG84 (clone LA-25.1) is a murine monoclonal antibody, subclass IgG2b recognizing OspB. Mice were immunized with recombinant OspB antigen. The antibody has been purified from cell culture supernatant using Protein G affinity chromatography.
Presentation
Screw capped vial containing 250 µg of purified antibody in PBS pH 7.4 + 0.01% ProClin300. Spin the vial briefly before opening. The IgG concentration is indicated on the vial label.
Storage and Stability
Store the antibody at 2°-8°C. For long-term storage the antibody should be aliquoted and stored at –20°C or colder. It is recommended to avoid freeze-thaw cycles.
