Anti-DDX4 / MVH antibody - Primordial Germ Cell Marker (ab13840)

  Immunohistochemistry (Frozen sections) - Anti-DDX4 / MVH antibody - Primordial Germ Cell Marker (ab13840)

Mouse embryonic gonad cells were fixed with 4% PFA, permeabilised and blocked with PBS, 1% BSA, 0.1% TX-100 and incubated with the DDX4 antibody, ab13840 (1 µg/ml) overnight at 4 degrees. ab13840 staining is shown in red and Oct4 staining is shown in green. 

The image shows that the anti-DDX4 antibody, ab13840, stains the cytoplasm of mouse primordial germ cells when used in IHC-Fr.

Ab13840 at 1/400 staining mouse fetal testis tissue sections by IHC-P. The tissue was blocked with both BSA and serum and fixed prior to incubation with the antibody for 3 hours at room temperature. A biotinylated secondary antibody was used (Vectastain Elite).

Please note Bouin's fluid was used as the fixative in this experiment.

  Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) - DDX4 / MVH antibody - Primordial Germ Cell Marker (ab13840)

IHC image of DDX4/MVH staining in human testis formalin fixed paraffin embedded tissue section, performed on a Leica Bond^TM system using the standard protocol F. The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH6, epitope retrieval solution 1) for 20 mins. The section was then incubated with ab13840, 5µg/ml, for 15 mins at room temperature and detected using an HRP conjugated compact polymer system. DAB was used as the chromogen. The section was then counterstained with haematoxylin and mounted with DPX.
