Immunoflouorescence Validation of ST2 in HeLa Cells. Immunofluorescent analysis of PFA-fixed HeLa cells labeling ST2 with orb1240035 at 20 µg/mL, followed by goat anti-rabbit IgG secondary antibody at 1/1000 dilution (red) and DAPI staining (blue). Alpha tubulin was stained with anti-alpha tubulin antibody following by goat anti-mouse IgG secondary antibody (green). Images were captured with confocal microscopy.

WB Validation in Human, Mouse, and Rat Cell Lines. Loading: 15 µg of lysate per lane Antibodies: ST2 orb1240035, 1 µg/mL, 1 h incubation at RT in 5% NFDM/TBST. Secondary: Goat Anti-Rabbit IgG HRP conjugate at 1:10000 dilution.

Western Blot Validation in 293 Cells. Antibodies: ST2 orb1240035, 1 µg/mL, 1 h incubation at RT in 5% NFDM/TBST. Secondary: Goat anti-rabbit IgG HRP conjugate at 1:10000 dilution. Lane A: In the absence of blocking peptide Lane B: In the presence of blocking peptide.

Western Blot Validation in Mouse Heart. Loading: 15 µg of lysate Antibodies: ST2 orb1240035, 1 µg/mL, 1 h incubation at RT in 5% NFDM/TBST. Secondary: Goat anti-rabbit IgG HRP conjugate at 1:10000 dilution.

Immunofluorescence Validation of ST2 in Human Lung. Immunofluorescent analysis of PFA-fixed human lung tissue labeling ST2 with orb1240035 at 10 µg/mL, followed by goat anti-rabbit IgG secondary antibody at 1/1000 dilution (red) and DAPI staining (blue).

Immunofluorescence Validation of ST2 in Human Lung Cancer Tissue. Immunofluorescent analysis of 4% paraformaldehyde-fixed human lung cancer tissue labeling ST2 with orb1240035 at 5 µg/mL, followed by goat anti-rabbit IgG secondary antibody at 1/500 dilution (green) DAPI staining (blue).

Immunofluorescence Validation of ST2 in Mouse Kidney. Immunofluorescent analysis of PFA-fixed mouse kidney tissue labeling ST2 with orb1240035 at 10 µg/mL, followed by goat anti-rabbit IgG secondary antibody at 1/1000 dilution (red) and DAPI staining (blue).

Immunohistochemistry Validation of ST2 in Rat Kidney. Immunohistochemical analysis of paraffin-embedded rat kidney tissue using anti-ST2 antibody (orb1240035) at 5 µg/mL. Tissue 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°C. A goat anti-rabbit IgG H&L (HRP) at 1/250 was used as secondary. Counter stained with Hematoxylin.
