WT1 Antibody (960525) [Unconjugated]

K562 Human chronic myelogenous leukemia cell line was stained with Mouse Anti-Human WT1 Monoclonal Antibody (Catalog # MAB57291, filled histogram) or Mouse IgG1Isotype Control Antibody (Catalog # MAB002, open histogram), followed by Allophycocyanin-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # F0101B). To facilitate intracellular staining, cells were fixed and permeabilized with FlowX FoxP3 Fixation & Permeabilization Buffer Kit (Catalog # FC012).

Background

WT1 (Wilms' tumor protein 1; also WT33) is a 52‑54 kDa, nuclear member of the EGR C2H2‑type zinc‑finger family of proteins. Although its predicted MW is 49 kDa, it runs anomalously in SDS‑PAGE, likely due to a high proline content. It is widely expressed, being found in developing Sertoli cells, glomerular podocytes, neurons, and CD34⁺ stem cells. Human WT1 is 449 amino acids (aa) in length. It contains a Pro‑rich domain (aa 27‑83) and four consecutive C2H2 zinc finger regions (aa 323‑347; 353‑377; 383‑405; 414‑438). WT1 forms homodimers, and interacts with multiple molecules. Interaction with the zinc fingers generally promotes gene transcription, while N‑terminal interactions block gene transcription. There are at least two dozen splice variants. Some are combinations of deletions of aa 250‑266 and 408‑410, plus an alternate start site 68 aa upstream of the standard site, and a three aa substitution for aa 1‑147. Over aa 127‑249, human WT1 shares 98% aa identity with mouse WT1.
