Product Details

Supplier Product No.: 000-001-c19

Supplier: Rockland

Purpose: Crasp2 Control Protein

Purification: Crasp2 is a fusion protein with an MBP tag and was expressed in E. coli. Analysis by SDS-PAGE resulted in a pattern consistent with purified Crasp2 and was estimated to be greater than 90% pure.

Sterility: Sterile filtered

Application Details

Application Notes:

Application Note: Crasp2 is suitable as a control in immunological assays. Specific conditions for reactivity should be optimized by the end user. Expect bands at 67.8 kDa for CRASP-2-MBP, (25.4 kDa for CRASP-2 and 42.4 kDa for MBP) and in size corresponding to Crasp2 by Western blotting in the appropriate cell lysate or extract. Complement Regulator-Acquiring Surface Protein 2 was tested in SDS-page and western blot.

Background:

Synonyms: control protein, Borrelia burgdorferi CRASP-2, CRASP2

Background: CRASP-2 (Complement Regulator-Acquiring Surface Protein 2) of Borrelia burgdorferi binds FHL-1 and factor H binding protein in a distinct way. It may be predominantly expressed by serum-resistant Borrelia strains. Borrelia burgdorferi sensu lato has the ability to evade immune systems to persist in a variety of vertebrate hosts. This activity is dependent on a number of factors. Some Borrelia species bind host-derived fluid-phase immune regulators FHL-1 and factor H to their surface via complement regulator-acquiring surface proteins (CRASPs). Factor H and FHL-1 serve as cofactors for factor I, a serine protease that cleaves complement component 3b (C3b) directly on the cell surface and thereby confers resistance of spirochetes to complement-mediated lysis. It is possible that because of discontinuous binding regions in the factor H/FHL-1, long distance interaction may be involved in binding of both immune regulators. Putative coiled-coil structural elements may be important in the interaction of B. burgdorferi CRASP-1 with factor H. Lyme disease proteins are ideal for researchers interested in immunology, neurology, rheumatology, coinfections, autoimmune, and neurodegenerative diseases.
