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 Immunoprecipitation, Flow Cytometry, Immunohistochemistry and in vitro functional studies. Other applications not tested.
Recommended Dilution:
Immunoprecipitation: 1:50
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.
