PAX8 encodes the paired box gene 8 protein, a member of the PAX transcription factor family. Common aliases include PAX8_HUMAN and thyroid transcription factor 3 (TTF-3). It binds specific DNA motifs to regulate target gene expression, playing critical roles in thyroid follicular cell development and renal tubular morphogenesis.
PAX8 intersects with thyroid hormone synthesis and Wnt signaling pathways. Its dysregulation is linked to thyroid cancers (e.g., papillary thyroid carcinoma) and renal cell carcinoma. No direct PAX8-targeted drugs are approved yet, but it serves as a diagnostic biomarker, with ongoing research exploring inhibitors of downstream pathways in PAX8-driven malignancies.

The Binding Activity of Human PAX8 with Anti-PAX8 Recombinant antibody
Activity: Measured by its binding ability in a functional ELISA. Immobilized Human PAX8 (CSB-MP017494HU2) at 2 μg/mL can bind Anti-PAX8 recombinant antibody. The EC50 is 0.6325-0.7353 ng/mL.
Overlay Peak curve showing 786-O cells stained with CSB-RA017494MA1HU (red line) at 1:100. The cells were fixed in 4% formaldehyde and permeated by 0.2% TritonX-100 for 10min. Then 10% normal goat serum to block non-specific protein-protein interactions followed by the antibody (1ug/1*106cells) for 45min at 4℃. The secondary antibody used was Fluorescein (FITC) AffiniPure Goat Anti-Human IgG, Fcγ fragment specific at 1:200 dilution for 35min at 4℃.Control antibody (green line) was human IgG1 (1ug/1*106cells) used under the same conditions. Acquisition of >10,000 events was performed.
