|Detection of Human FoxD3 by Western Blot. Western blot shows lysates of HEK293 human embryonic kidney cell line either mock transfected or transfected with human FoxD3. PVDF Membrane was probed with 1 µg/mL of Sheep Anti-Human FoxD3 aa 1-140 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF2819) followed by HRP-conjugated Anti-Sheep IgG Secondary Antibody (Catalog # HAF016). A specific band was detected for FoxD3 at approximately 60 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.|
|FoxD3 in BG01V Human Stem Cells. FoxD3 was detected in immersion fixed BG01V human embryonic stem cells using Sheep Anti-Human FoxD3 aa 1-140 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF2819) at 10 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Sheep IgG Secondary Antibody (red, upper panel; Catalog # NL010) and counterstained with DAPI (blue, lower panel). Specific staining was localized to nuclei and cytoplasm. View our protocol for Fluorescent ICC Staining of Cells on Coverslips.|
FOXD3 (forkhead box protein D3; also HNF3, HFH2 and Genesis) is a 58-60 kDa member of the winged helix transcription factor gene family. It is expressed in the epiblast, migrating neural crest, and neural progenitors of the developing spinal cord. FOXD3 is believed to maintain an uncommitted state in multipotent neural crest stem cells, and to induce cell cycle arrest via p53 and p21cip1. Human FOXD3 is 478 amino acids (aa) in length. It contains a forkhead DNA binding domain (aa 141‑235) plus an Ala-rich region (aa 262-473). Over aa 1-140 and 302-462, human FOXD3 shares 76% and 91% aa identity with mouse FoxD3, respectively.
