Detects human DPPA4 in direct ELISAs and Western blots. In direct ELISAs, approximately 5% cross-reactivity with recombinant mouse DPPA4 is observed and less than 1% cross-reactivity with recombinant human DPPA5 is observed.
Polyclonal Sheep IgG
E. coli-derived recombinant human DPPA4 Met1-Glu304 Accession # Q7L190
Lyophilized from a 0.2 μm filtered solution in PBS with Trehalose. *Small pack size (SP) is supplied as a 0.2 µm filtered solution in PBS.
Detection of DPPA4 in NTera‑2 Human Cell Line by Flow Cytometry.
NTera‑2 human testicular embryonic carcinoma cell line was stained with Sheep Anti-Human DPPA4 Antigen Affinity‑purified Polyclonal Antibody (Catalog # AF3674, filled histogram) or isotype control antibody (Catalog # 5‑001‑A, open histogram), followed by NorthernLights™ 557-conjugated Anti-Sheep IgG Secondary Antibody (Catalog # NL010). To facilitate intracellular staining, cells were fixed with paraformaldehyde and permeabilized with saponin.
DPPA4 in Human iPSK3 cells.
DPPA4 was detected in immersion fixed human plasmid-derived induced pluripotent stem cells (iPSK3) using Sheep Anti-Human DPPA4 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF3674) at 10 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Sheep IgG Secondary Antibody (red; Catalog # NL010) and counterstained with DAPI (blue). Specific staining was localized to nuclei.

DPPA4 is a nuclear SAP-domain protein whose expression is restricted to pluripotent cells, undifferentiated embryonal carcinomas and germ cell tumors. It is considered a marker for embryonic stem cells. Human DPPA4 shares 51% amino acid sequence homology with mouse DPPA4.
