Background Information

PAX8 is a member of the paired box (PAX) family of transcription factors, typically containing a paired box domain and a paired-type homeodomain. It is expressed during organogenesis of the thyroid gland, kidney and Mullerian system. It is thought to regulate the expression of Wilms tumor suppressor (WT1) gene and mutations in PAX8 have been associated with Wilms tumor cells, thyroid and ovarian carcinomas. PAX8 is a useful marker in distinguishing ovarian carcinomas from mammary carcinomas (PMID: 18724243). PAX8 is expressed in a high percentage of ovarian serous, endometrioid, and clear cell carcinomas, but only rarely in primary ovarian mucinous adenocarcinomas.

This antibody can detect all 5 isoforms of PAX8 (31 kDa, 34 kDa, 41 kDa, 43 kDa and 48 kDa). A 58-60 kDa form has also been reported (PMID:15650356, 1049952). Proteintech's 10336-1-AP antibody has cross-reactivities with the other PAX family members.

shuang (Verified Customer) (02-18-2020)

This Pax8 antibody works great for both IHC and IF staining on mouse Fallopian tube/uterus organoids and tumors, Highly recommend!

  • Applications: Immunohistochemistry, Immunofluorescence,
  • Primary Antibody Dilution: 1:100
  • Cell Tissue Type: mouse Fallopian tube/ Fallopian tube organoids

Adam (Verified Customer) (05-30-2019)

Antibody works great for our applications (IHC on FFPE tissues). Only comment is that it cane sometimes have some background staining, particularly in some mouse tissues such as liver.

  • Applications: Immunohistochemistry,
  • Primary Antibody Dilution: 1:1000

Huai-Chin (Verified Customer) (04-15-2019)

So far only try the antibody for IHC on mouse tissue. Works pretty good. Would like to try it on human tissue/cell lines.

  • Applications: Immunohistochemistry,
  • Primary Antibody Dilution: 1:500
  • Cell Tissue Type: Mouse Ovary/Oviduct

Paulo (Verified Customer) (03-03-2019)

Used to perform ChIP-seq in ccRCC cell lines. 17.5ug of antibody used in 100million cells. IP was validated by WB. Sequencing detected PAX8 binding genome wide. Motif analysis identified the consensus PAX8 binding motif in approximately 90% of detected peaks.Would be great if Proteintech would produce a more concentrated version of this antibody for ChIP-seq.

  • Applications: ChIP,
