Recombinant Anti-CDX2 antibody [SP54] (ab101532)

Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) analysis of Human colon carcinoma tissue sections labeling CDX2 with ab101532 at 1/100 dilution (1.11 μg/ml). Heat mediated antigen retrieval with Citrate buffer (pH 6.0, epitope retrieval solution 1) for 20 mins. Goat Anti-Rabbit & Mouse IgG (HRP) was used as the secondary antibody. Hematoxylin was used as a counterstain. Positive staining on the human colon carcinoma, performed on a Leica Biosystems BOND™ RX instrument.
The section was incubated with ab101532 for 30 mins at room temperature.

Immunocytochemistry/ Immunofluorescence analysis of Caco-2 (human colorectal adenocarcinoma epithelial cell) cells labeling CDX2 with purified ab101532 at 1/50 (2.22 µg/ml). Cells were fixed in 4% paraformaldehyde and permeabilized with 0.1% Triton X-100. Cells were counterstained with ab195889 Anti-alpha Tubulin antibody [DM1A] - Microtubule Marker (Alexa Fluor^® 594) 1/200 (2.5 µg/ml). Goat anti rabbit IgG (Alexa Fluor^® 488, ab150077) was used as the secondary antibody at 1/1000 (2 µg/ml) dilution. DAPI was used as nuclear counterstain. PBS instead of the primary antibody was used as the secondary antibody only control.

Flow cytometry analysis of Caco-2 (human colorectal adenocarcinoma epithelial cell) labeling CDX2 with purified ab101532 at 1/200 dilution (0.56 µg/ml) (red). Cells were fixed with 4% paraformaldehyde and permeabilised with 90% methanol. Goat anti rabbit IgG (Alexa Fluor^® 488, ab150077) at 1/2000 dilution was used as a secondary antibody. Isotype control -Rabbit monoclonal IgG (ab172730) (black). Unlableled control -Unlabelled cells (blue).
