Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) - Anti-IL-18 antibody [EPR19954-188] - BSA and Azide free (AB243295)

Immunohistochemical analysis of paraffin-embedded human liver tissue labeling IL-18 with ab243091 at 1/250 dilution, followed by Goat Anti-Rabbit IgG H&L (HRP) Ready to use. Cytoplasmic staining on Kupffer cells in human liver (PMID : 19084941). Counter stained with hematoxylin.

Secondary antibody only control : Used PBS instead of primary antibody, secondary antibody is Goat Anti-Rabbit IgG H&L (HRP) Ready to use.

Heat mediated antigen retrieval using ab93684 (Tris/EDTA buffer, pH 9.0).

This data was developed using the same antibody clone in a different buffer formulation containing PBS, BSA, glycerol, and sodium azide (ab243091).

Western blot - Anti-IL-18 antibody [EPR19954-188] - BSA and Azide free (AB243295)

This data was developed using the same antibody clone in a different buffer formulation (ab243091).

Lanes 1-4 : Merged signal (red and green). Green - ab243091 observed at 22 kDa. Red - loading control ab8245 observed at 37 kDa.

ab243091 Anti-IL-18 antibody [EPR19954-188] was shown to specifically react with IL-18 in wild-type HeLa cells. Loss of signal was observed when knockout cell line ab265274 (knockout cell lysate ab256952) was used. Wild-type and IL-18 knockout samples were subjected to SDS-PAGE. ab243091 and Anti-alpha Tubulin antibody [EP1332Y] - Microtubule Marker (ab52866) were incubated overnight at 4°C at 1 in 1000 dilution and 1 in 20000 dilution respectively. Blots were developed with Goat anti-Rabbit IgG H&L (IRDye^® 800CW) preadsorbed (ab216773) and Goat anti-Mouse IgG H&L (IRDye^® 680RD) preadsorbed (ab216776) secondary antibodies at 1 in 20000 dilution for 1 hour at room temperature before imaging.
