General description

Octamer-4 (Oct-4), a member of the POU family of transcription factors, has been demonstrated to be vital for the formation of self-renewing pluripotent stem cells. During embryogenesis expression of Oct-4 is limited to pluripotent cells of the inner cell mass (ICM) that contribute to the formation of all fetal cell types. This relationship between Oct-4 and pluripotency has seen this transcription factor emerge as a marker of pluripotent stem cells. Undifferentiated human and murine pluripotent Embryonic Stem (ES) and Embryonic Carcinoma (EC) cells express Oct-4. Additionally, murine Embryonic Germ (EG) cells are also known to express Oct-4. Following stem cell differentiation, the level of Oct-4 expression decreases. Oct-4 expression by human EG cells is not known.

Specificity

Reacts with human Oct-4 only, and detects the Oct-4A isoform. (Note: Please order Catalog No. MAB4419 for use with mouse embryonic stem cells).
The clone reacts strongly with specific nuclear binding to human ES cells and cross-reacts weakly with mouse ES cells.

Immunogen

Epitope: unknown
KLH-EDC-conjugated linear peptide corresponding to the unknown of Human Oct-4.

Application

Immunocytochemistry Analysis: A 1:1000 dilution from a representative lot detected human Oct-4 in 10 µg of H9 human ES cells.

Developmental Signaling
This Anti-Human Oct-4 Antibody is validated for use in Western Blotting and Immunocytochemistry for the detection of Human Oct-4.

Quality

Evaluated by Western Blotting in H9 human ES cell lysate and mouse ES cells lysate.

Western Blotting Analysis: A 0.25 µg/mL dilution of this antibody detected human Oct-4 in 10 µg of H9 human ES cell lysate but not in 10 µg of mouse ES cells lysate.

Target description

During embryonic development, excitatory projection neurons migrate in the cerebral cortex giving rise to organised layers. Periventricular heterotopia (PH) is a group of aetiologically heterogeneous disorders in which a subpopulation of newborn projection neurons fails to initiate their radial migration
