Immunofluorescence analysis of Thomsen Friedenreich Antigen was performed using 70% confluent log phase HT-29 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 Thomsen-Friedenreich Antigen (A78-G/A7) Mouse Monoclonal Antibody (MA513466) 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 (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 (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 membranous localization. Panel e shows the no primary antibody control. The images were captured at 60X magnification.

MA5-13466 targets Thomsen-Friedenreich Antigen in immunofluorescence and immohistochemistry (Paraffin) applications and shows reactivity with Human and Rat samples. Staining of formalin-fixed tissues requires boiling tissue section in 10 mM citrate buffer, pH 6.0 for 10-20 minutes followed by cooling at room temperature for 20 minutes.
The MA5-13466 immunogen is neuraminidase-treated human red blood cells.
The Thomsen-Fridenreich antigen acts as an oncofetal antigen, with low expression in normal adult tissues but increasing to fetal levels of expression in hyperplasia or malignancy. It is considered as a pan-carcinoma marker.

Infection of swine ex vivo tissues with avian viruses including H7N9 and correlation with glycomic analysis.
MA5-13466 was used in immunohistochemistry to study the sialylated N-glycan and O-glycan content of the pig resiratory tract and the significance for ex vivo infection by avian viruses
