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.

Immunogen

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

Epitope: unknown

Other Notes

Concentration: Please refer to lot specific datasheet.

Physical form

Purified rabbit Polyclonal in buffer containing 0.1 M Tris-Glycine (pH 7.4), 150 mM NaCl with 0.05% sodium azide.

Antigen Affinity Purified

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.

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.

Storage and Stability

Stable for 1 year at 2-8°C from date of receipt.
