Western blot analysis of CD31 on different lysates with Rabbit anti-CD31 antibody (ER31219) at 1/1,000 dilution.
Lane 1: THP-1 cell lysate (10 µg/Lane)
Lane 2: NIH/3T3 cell lysate (negative) (10 µg/Lane)
Lane 3: Mouse lung tissue lysate (40 µg/Lane)
Lane 4: Rat lung tissue lysate (40 µg/Lane)
Predicted band size: 83 kDa
Observed band size: 120-130 kDa
Exposure time: Lane 1: 16 seconds; Lane 2-4: 1 minute 2 seconds; ECL: K1801;
4-20% SDS-PAGE gel.
Proteins were transferred to a PVDF membrane and blocked with 5% NFDM/TBST for 1 hour at room temperature. The primary antibody (ER31219) at 1/1,000 dilution was used in 5% NFDM/TBST at 4℃ overnight. Goat Anti-Rabbit IgG - HRP Secondary Antibody (HA1001) at 1/50,000 dilution was used for 1 hour at room temperature.

Immunohistochemical analysis of paraffin-embedded human lung tissue with Rabbit anti-CD31 antibody (ER31219) at 1/5,000 dilution.
The section was pre-treated using heat mediated antigen retrieval with Tris-EDTA buffer (pH 9.0) for 20 minutes. The tissues were blocked in 1% BSA for 20 minutes at room temperature, washed with ddH2O and PBS, and then probed with the primary antibody (ER31219) at 1/5,000 dilution for 1 hour at room temperature. The detection was performed using an HRP conjugated compact polymer system. DAB was used as the chromogen. Tissues were counterstained with hematoxylin and mounted with DPX.

Immunohistochemical analysis of paraffin-embedded human tonsil tissue with Rabbit anti-CD31 antibody (ER31219) at 1/1,000 dilution.
The section was pre-treated using heat mediated antigen retrieval with Tris-EDTA buffer (pH 9.0) for 20 minutes. The tissues were blocked in 1% BSA for 20 minutes at room temperature, washed with ddH2O and PBS, and then probed with the primary antibody (ER31219) at 1/1,000 dilution for 1 hour at room temperature. The detection was performed using an HRP conjugated compact polymer system. DAB was used as the chromogen. Tissues were counterstained with hematoxylin and mounted with DPX.
