Figure 6 Immunocytochemistry Validation of IRAK in Human HeLa CellsImmunocytochemical analysis of HeLa cells using anti-IRAK antibody (1007) at 10 &956,g/ml. Cells was fixed with formaldehyde and blocked with 10% serum for 1 h at RT, antigen retrieval was by heat mediation with a citrate buffer (pH6). Samples were incubated with primary antibody overnight at 4&730, C. A goat anti-rabbit IgG H&L (HRP) at 1/250 was used as secondary. Counter stained with Hematoxylin. |

Figure 7 Immunoprecipitation and Overexpression Validation in HEK293T Cells(Schauvliege et al., 2006)Co-expression of Pellino proteins and IRAK-1 leads to Pellino phosphorylation and IRAK-1 polyubiquitination. (A) E-tagged Pellino proteins were co-expressed with IRAK-1WT and HA-ubiquitin in HEK293T cells. For assessment of IRAK-1 polyubiquitination, the same cellextracts, untreated or treated with phosphatase as described above, were analysed for slower migrating forms of IRAK-1 by Western blotting withanti-IRAK-1 (1007). Ubiquitination was specifically detected by IRAK-1 immunoprecipitation followed by Western blotting with anti-HA antibodies. |

Figure 8 KD Validation in Human Chondrocytes (Ahmad et al., 2007)Chondrocytes were transfected with 250 nM of IRAK1 or control siRNA for 48 h and lysates were analyzed for IRAK1 or beta-actin expression levels by immunoblotting. IRAK1 signal was disrupted in IRAK1 KD lysate. |
