Description

M9.D6 is generated against a peptide derived from the extracellular portion of mouse TLR9. Predominantly expressed as an intracellular protein, TLR9 is a ~115-120 kDa molecule which mediates response to unmethylated CpG dinucleotides in bacterial DNA. CpG DNA induces a strong T-helper-1-like inflammatory response and the proliferation of TLR9+ B cells. When stimulated with CpG DNA, TLR9-deficient (TLR9-/-) mice lacked splenocyte proliferation, inflammatory cytokine production from macrophages, and dendritic cell maturation, as compared with normal mice. To date, at least ten members of the Toll family have been identified. This family of type I transmembrane proteins is characterized by an extracellular domain with leucine-rich repeats and a cytoplasmic domain with homology to the type I IL-1 receptor. Members of the TLR family are involved in recognition and response to different microbial components including lipoproteins, peptidoglycans, and nucleic acids and play important roles in innate immunity and inflammation. TLR9 is not detected by flow cytometry using this antibody on RBC-lysed mouse splenocytes stained for intracellular TLR9. This may be due to limitations of antigen detection by flow cytometry. Further studies are needed to determine the relationship between mRNA expression and protein detection.

Applications Reported

For research use only, not for diagnostic or therapeutic use. This M9.D6 antibody has been reported for use in intracellular flow cytometric analysis.

Applications Tested

This M9.D6 antibody has been tested by intracellular staining and flow cytometric analysis of fixed and permeabilized mouse TLR9 transfected 293T cells. This can be used at less than or equal to 0.5 μg per million cells in a 100 μl total staining volume. It is recommended that the antibody be carefully titrated for optimal performance in the assay of interest.
