FOXD3 Transcription Factor Activity Assay

The FOXD3 Transcription Factor Activity Assay from Assay Genie is a DNA-binding ELISA kit that quantifies the active DNA-binding capability of FOXD3 (Forkhead Box D3) in nuclear and cell lysates. Rather than simply measuring total FOXD3 protein abundance, this transcription factor activity assay captures functionally competent FOXD3 through its interaction with an immobilized consensus forkhead response element, delivering a direct readout of transcription factor activation status for research use.

The microplate-based colorimetric procedure uses nuclear extracts prepared from cultured cells or tissue, with reactivity validated across human, mouse, and rat samples. Investigators studying neural crest specification, melanoma cell plasticity, pluripotent stem cell maintenance, or developmental signaling can monitor FOXD3 activation following genetic manipulation, pharmacological treatment, or differentiation cues. Reagents are supplied as a complete kit with all buffers, the coated plate, and detection antibody included for 96 Assays; components should be stored refrigerated and protected from light to preserve activity through the listed shelf life.
