- Western blot was performed using Anti-Cytokeratin 7 Monoclonal Antibody (RCK105) (Product # MA1-06315) and a 51kDa band corresponding to Cytokeratin 7 was observed across cell lines tested. Whole cell extract (30ug lysate) of HeLa (Lane 1), A549 (Lane 2), NIH:OVCAR-3 (Lane 3), A-431 (Lane 4), SK-O-V3 (Lane 5) were electrophoresed using NuPAGE™ 4-12% Bis-Tris Protein Gel (Product # NP0322BOX). Resolved proteins were then transferred onto a Nitrocellulose membrane (Product # LC2002) by iBlot® 2 Dry Blotting System (Product # IB21001). The blot was probed with the primary antibody (1:1000 Dilution) and detected by chemiluminescence with Goat anti-Mouse IgG (H+L) Superclonal™ Recombinant Secondary Antibody, HRP (Product # A28177, 1:4000 Dilution) using the iBright FL 1000 (Product # A32752). Chemiluminescent detection was performed using Novex® ECL Chemiluminescent Substrate Reagent Kit (Product # WP20005). Expression of KRT7 was found to be higher in HeLa, A549 and NIH:OVCAR-3 as compared to A-431 and SK-O-V3 cells.

- Immunofluorescence analysis of Cytokeratin 7 was performed using 70% confluent log phase HeLa cells. The cells were fixed with 4% paraformaldehyde for 10 minutes, permeabilized with 0.1% Triton™ X-100 for 15 minutes, and blocked with 2% BSA for 45 minutes at room temperature. The cells were labeled with Cytokeratin 7 Monoclonal Antibody (RCK105) (Product # MA1-06315) at 1:200 dilution in 0.1% BSA, incubated at 4 degree celsius overnight and then labeled with Goat anti-Mouse IgG (H+L) Highly Cross-Adsorbed Secondary Antibody, Alexa Fluor Plus 488 (Product # A32723), (1:2000), for 45 minutes at room temperature (Panel a: Green). Nuclei (Panel b:Red) were stained with ProLong™ Diamond Antifade Mountant with DAPI (Product # P36962). F-actin (Panel c: Blue) was stained with Rhodamine Phalloidin (Product # R415, 1:300). Panel d represents the merged image showing cytoplasmic localization. Panel e represents control cells with no primary antibody to assess background. The images were captured at 60x magnification.

- FIGURE 4 Parasympathetic innervation increases ductal epithelial cell proliferation. (A) Immunofluorescence staining of cytokeratin 7 (green), Ki67 (red) and DAPI (blue) in the submandibular glands during gland regeneration in different groups. Scale bar =20 mum. (B) The number of Ki67+ in ductal and non-ductal cells was different. The relative expression of ki67+ was maintained a stable state at days 14 and 28. *** indicates significance at P < .001, ** P < .01, * P < .05, ns for no significant. Data were shown as mean +- standard deviation
