CD180 is a type 1 transmembrane protein of 105kD with extracellular leucine-rich repeats (LLRs) and a short cytoplasmic tail. CD180 is similar to Drosophila Toll in the extracellular LLRs. CD180 expression is largely restricted to immune cells including CD19+ B cells and macrophages. Histological studies showed that CD180 is expressed mainly on mature B cells in mantle zones. Antibody-mediated (MHR73) cross-linking of CD180 induces resistance against irradiation-induced apoptosis, B-cell proliferation, and up-regulation of a costimulatory molecule CD80, revealing CD180 as a potent regulator of B-cell activation. In this context it is important to note that CD180 is associated with MD1, and that it mediates B-cell surface expression and LPS recognition and signalling in cooperation with TLR4. MD-1 seems to be requisite for efficient expression of CD180. Applications: Suitable for use in Flow Cytometry and Immunohistochemistry. Other applications not tested. Recommended Dilution: Flow Cytometry: 1:50 Immunohistochemistry (frozen): 1:50 Optimal dilutions to be determined by the researcher. Storage and Stability: For long-term storage and to avoid repeated freezing and thawing, aliquot and store at -20 degrees C. Aliquots are stable for at least 12 months at -20 degrees C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer. FITC conjugates are sensitive to light.
