murine MAb against tick saliva protein Cystatin_1 (SialoL) of Ixodes ricinus, clone Cyst1-2
Description
Access to a nutritious blood meal has been gained independently numerous times and in various families and orders during invertebrate evolution. Hard ticks feed on their hosts for several days and have evolved a series of strategies to circumvent host defenses during their prolonged meal. Among them, the shedding of saliva in the sites of bite(s) possesses a critical role. Tick saliva contains a broad repertoire of potent pharmacologic molecules with vasoactive, anti-hemostatic, antiinflammatory, and immunomodulatory action. Tick cystatins either regulate hemoglobin digestion, which is driven by cathepsins, or they can be secreted as immunomodulators into the host with saliva. One of the best studied tick cystatins is sialostatin L, a type 2 cystatin detected in I. scapularis.
Properties
The monoclonal antibody ADG0191L (Cyst1-2) is a murine monoclonal antibody, subclass IgG1 recognizing saliva protein Cystatin_1/SialoL of Ixodes ricinus /I. scapularis. Mice were immunized with rec. Cystatin_1. The antibody has been purified from cell culture supernatant using Protein G affinity chromatography.
Presentation
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.
Applications
ELISA
The antibody can be used as capture antibody in ELISAs. An antibody concentration of 1-10 µg/ml is recommended.
Westernblot
The antibody is suitable for Western blot analysis, detecting native and recombinant Cystatin_1/SialoL following SDS-PAGE under reducing conditions. A primary antibody concentration of 1-10 µg/mL is recommended.
Immunocytochemistry
The antibody can be used for immune-cytochemistry.
