  • Function
    Key component of innate and adaptive immunity. TLRs (Toll-like receptors) control host immune response against pathogens through recognition of molecular patterns specific of microorganisms. TLR9 is a nucleotide-sensing TLR which is activated by unmethylated cytidine-phosphate-guanosine (CpG) dinucleotides. Acts via MYD88 and TRAF6, leading to NF-kappa-B activation, cytokine secretion and the inflammatory response.
  • Tissue specificity
    Highly expressed in spleen, lymph node, tonsil and peripheral blood leukocytes, especially in plasmacytoid pre-dendritic cells. Levels are much lower in monocytes and CD11c+ immature dendritic cells. Also detected in lung and liver.
  • Sequence similarities
    Belongs to the Toll-like receptor family.
    Contains 26 LRR (leucine-rich) repeats.
    Contains 1 TIR domain.
  • Cellular localization
    Endoplasmic reticulum membrane. Endosome. Lysosome. Cytoplasmic vesicle > phagosome. Relocalizes from endoplasmic reticulum to endosome and lysosome upon stimulation with agonist.

Thank you for contacting Abcam about ab37154. Please find below the suggested standard IHC-P protocol recommended for this antibody, however you may need to optimize it for your own specific needs. Standard Protocol: BUFFERS Working Citrate Buffer 9mL of 0.1M Citric Acid (10.5g citric acid monohydrate to 500mL DI H2O) 41mL of 0.1M Sodium Citrate (14.7g sodium citrate dehydrate to 500mL DI H2O) 450mL of DI H2O Deparaffinization and Rehydration (Cover staining dishes with a lid in each step) 1. Dip slides in three (3) changes of xylene or a xylene substitute for 3 minutes each. 2. Dip slides in two (2) change of 100% alcohol for 3 minutes each. 3. Dip slides in one (1) change of 95% alcohol for 3 minutes. 4. Dip slides in one (1) change of 70% alcohol for 3 minutes. 5. Rinse slides twice (2x) in DI H2O for 5 minutes. Antigen Retrieval (Microwave Method) 6. Soak slides in 3% H2O2 for 5 minutes. 7. Rinse slides twice (2x) in DI H2O for 5 minutes. 8. Soak the slides in the working citrate buffer and cover with a lid. 9. Microwave until the liquid boils, about 1-5 minutes. 10. Remove from heat and let it stand at room temperature for 20 minutes. Page 2 of 2 11. Wash three (3) times for 5 minutes in DI H2O 12. Remove the liquid (do not touch the tissue!) and use a PAP pen to circle around the tissue. Blocking 13. Apply enough 5% BSA with a transfer pipette to cover the tissues. 14. Incubate the slides overnight at 4°C in a humid chamber. Primary Antibody 15. Dilute the primary antibody to the recommended concentration in 1% BSA/PBS diluent. 16. Remove the BSA, and incubate with primary antibody solution for 1 hour at room temperature. 17. Wash slides three (3) times 5 minutes each on the shaker. Secondary Antibody and Detection 18. Dilute the biotinylated secondary antibody to 1:200 in 1% BSA diluent. 19. Incubate with secondary antibody solution for 30 minutes at room temperature. 20. Wash slides in PBS three (3) times 5 minutes each on the shaker. 21. Add enough streptavidin HRP to cover the tissues. Incubate for 30 minutes at room temperature 22. Wash three (3) times 5 minutes each in PBS on the shaker. 23. Add enough DAB to cover the tissues. Once the cells start turning brown (inexperienced technicians may wish to observe this under a microscope), wash twice (2x) in PBS for 5 minutes each on the shaker.
