- Immunofluorescence analysis of MSH2 was performed using 90% confluent log phase Raji cells. The cells were fixed with 4% paraformaldehyde for 10 minutes, permeabilized with 0.1% Triton™ X-100 for 10 minutes, and blocked with 1% BSA for 1 hour at room temperature. The cells were labeled with MSH2 (FE11) Mouse Monoclonal Antibody (Product # 33-7900) at 2µg/mL in 0.1% BSA and incubated for 3 hours at room temperature and then labeled with Goat anti-Mouse IgG (H+L) Superclonal™ Secondary Antibody, Alexa Fluor® 488 conjugate (Product # A28175) at a dilution of 1:2000 for 45 minutes at room temperature (Panel a: green). Nuclei (Panel b: blue) were stained with SlowFade® Gold Antifade Mountant with DAPI (Product # S36938). F-actin (Panel c: red) was stained with Alexa Fluor® 555 Rhodamine Phalloidin (Product # R415, 1:300). Panel d represents the merged image showing nuclear localization. Panel e shows the no primary antibody control. The images were captured at 60X magnification.

Esophageal squamous neoplastic tissue obtained from endoscopic resection was stained with antibodies against FHIT, E-cadherin and MLH1/MSH2. (A) A HGIN/CIS lesion with reduced FHIT immunostaining, with positive staining of the adjacent germinal center and infiltrating lymphocytes. (B) A HGIN/CIS lesion with negative E-cadherin immunostaining. (C) A HGIN/CIS lesion with negative MLH1 immunostaining. (D) A HGIN/CIS lesion with positive MSH1 immunostaining. FHIT, fragile histidine triad; MLH1, MutL homolog 1; MSH1, MutS homolog 1; HGIN/CIS, high-grade intraepithelial neoplasia/carcinoma in situ .
