murine MAb against CRASP-1/cspA of Borrelia burgdorferi, Clone RH-1

Lyme disease is the most common vector-borne disease in North America and Europe. The causative agent Borrelia burgdorferi is a bacterium that is maintained in an enzoonotic cycle between Ixodes ticks and a large range of mammals. Adaptation to the diverse environmental conditions, including sophisticated means of evading the vertebrate hosts' immune system, in particular complement occurs at the first line of defense following infection. Borrelia burgdorferi spirochetes express up to five complement regulator-acquiring surface proteins (CRASPs) binding human complement regulators.

The monoclonal antibody ADG0121L (clone RH1) is a murine monoclonal antibody, subclass IgG2b recognizing CRASP-1/BBA68. Mice were immunized with cell lysates of Borrelia burgdorferi. The antibody has been purified from cell culture supernatant using Protein G affinity chromatography.

Screw capped vial containing 1 mg of purified antibody in PBS pH 7.4. The IgG concentration is given on the vial label. Spin the vial briefly before opening.

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.

The antibody can be used as capture antibody in ELISAs. An antibody concentration of 1-10 µg/ml is recommended.
The antibody can be used for immunocytochemistry on paraformaldehyde fixed spirochetes.
The antibody is suitable for Western blot analysis, detecting native and recombinant CRASP-1/BBA68 following SDS-PAGE under reducing conditions. A primary antibody concentration of 1-10 µg/mL is recommended.


burgdorferi cells were incubated with the indicated conc. (µg/ml) of the indicated proteases and lysed by sonication, and analyzed by Western blotting. CRASP-1/BBA68 was visualized using mAb RH1.
