Scientific Data

Western Blot Detection of Human Pax7 antibody by Western Blot. View Larger

Detection of Human Pax7 by Western Blot. Western blot shows lysates of human muscle tissue. PVDF Membrane was probed with 0.5 µg/mL of Goat Anti-Human Pax7 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF6670) followed by HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF019). A specific band was detected for Pax7 at approximately 57 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 8.

Pax7 in TT Cell Line (Positive) and THP‑1 Cell Line (Negative). Pax7 was detected in immersion fixed TT Human Medullary Thyroid Cancer Cell Line (Positive) and absent in THP‑1 Human Acute Monocytic Leukemia Cell Line (Negative) using Goat Anti-Human Pax7 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF6670) at 5 µg/mL for 1 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Goat IgG Secondary Antibody (red; Catalog # NL001) and counterstained with DAPI (blue). Specific staining was localized to cell nuclei. View our protocol for Fluorescent ICC Staining of Cells on Coverslips.

Background: Pax7

PAX7 (Paired box 7A; also HuP1) is a 57 kDa member of the paired homeobox family of transcription factors. It is expressed in select neurons (in rodent) and skeletal muscle satellite cells, where, in the latter, it promotes both a muscle stem cell state (PAX7+ desmin- cells) and a lineage commitment state (PAX7+ desmin+ cells). PAX7 forms heterodimers with PAX3, and interacts with the regulatory regions of the Myf5 locus. Human PAX7(A) is 520 amino acids (aa) in length. It contains an N‑terminal paired box DNA-binding domain (aa 34-163), a homeodomain (aa 218-275) and a C-terminal poly-alanine region (aa 340-346). Multiple splice forms of PAX7 exist. There is a 54 kDa isoform B that contains a 38 aa substitution for aa 468-520, plus a second isoform that shows a deletion of Gly151 and Leu152. There is also a chromosomal rearrangement that fuses aa 30-385 of PAX7 to aa 211-265 of FOXO1A/FKHR. Over aa 1-196, human PAX7 shares 86% and 96% aa identity with human PAX3 and mouse PAX7, respectively.
