Description: This 2A5 monoclonal antibody reacts with Foxj1, a 50-kDa member of the Forkhead-box (FOX) family of winged-helix transcription factors. Expression of Foxj1 is high in ciliated epithelial cells and low in naive T and B cells, where cellular activation results in downregulation of the factor. Foxj1 modulates germinal center formation and Th1 activation by repressing NFkappaB through IkappaBbeta induction. As such, this transcription factor has been suggested to antagonize autoimmune reactions such as systemic lupus erythematosus and rheumatoid arthritis. In addition, Foxj1 has been linked to the formation of motile cilia in epithelial cells.
Applications Reported: This 2A5 antibody has been reported for use in western blotting, immunohistochemical staining of formalin-fixed paraffin embedded tissue sections, and immunocytochemistry.
Applications Tested: This 2A5 antibody has been tested by western blot of mouse tracheal epithelial cells and testes, as well as by immunohistochemistry of mouse lung tissue. This antibody can be used between 1-10 µg/mL. It is recommended that the antibody be carefully titrated for optimal performance in the assay of interest.
Purity: Greater than 90%, as determined by SDS-PAGE.
Aggregation: Less than 10%, as determined by HPLC.
Filtration: 0.2 µm post-manufacturing filtered.
Recently, a novel member of the leukocyte receptor complex (LRC)-encoded family has been identified that is expressed specifically in osteoclast (OC). This protein names OC-associated receptor or OSCAR, play critical roles in the regulation of both innate and adaptive immune responses and bone-specific regulator of OC differentiation. Osteoclasts are multinucleated cells that resorb bone and are essential for bone homeostasis. This protein family plays critical roles in the regulation of both innate and adaptive immune responses. Different from the other LRC members, OSCAR expression is detected specifically in preosteoclasts or mature osteoclasts. OSCAR may be an important bone-specific regulator of osteoclast differentiation. Multiple alternatively spliced transcript variants encoding different isoforms have been found for this gene.
