	Fig1: All lanes: Western blot analysis of Cytokeratin-7 with anti-Cytokeratin-7 antibody [3-G3-D8] (EM0702) at 1:1,000 dilution. Lane 1/2: Wild-type Hela whole cell lysate. Lane 3/4: Cytokeratin-7 fragment 1 knockout Hela whole cell lysate. Lane 5/6: Cytokeratin-7 fragment 2 knockout Hela whole cell lysate. EM0702 was shown to specifically react with Cytokeratin-7 in wild-type Hela cells. No band was observed when Cytokeratin-7 knockout samples were tested. Wild-type and Cytokeratin-7 knockout samples were subjected to SDS-PAGE. Proteins were transferred to a PVDF membrane and blocked with 5% NFDM in TBST for 1 hour at room temperature. The primary antibody (EM0702, 1/1,000) and Loading control antibody(Rabbit anti-Vinculin, ET1705-94, 1/5,000) was used in 5% BSA at room temperature for 2 hours. Goat Anti-Mouse IgG-HRP Secondary Antibody (HA1006) at 1:20,000 dilution was used for 1 hour at room temperature.

The primary antibody (EM0702, 1/500) was used in 5% BSA at room temperature for 2 hours. Goat Anti-Mouse IgG - HRP Secondary Antibody (HA1006) at 1:100,000 dilution was used for 1 hour at room temperature.

	Fig3: Immunohistochemical analysis of paraffin-embedded human lung bronchus tissue using anti-Cytokeratin 7 antibody. The section was pre-treated using heat mediated antigen retrieval with Tris-EDTA buffer (pH 8.0-8.4) for 20 minutes.The tissues were blocked in 5% BSA for 30 minutes at room temperature, washed with ddH₂O and PBS, and then probed with the primary antibody (EM0702, 1/200) for 30 minutes 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.

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 (EM0702) at 1/800 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.
