Detection of Human HHEX by Western Blot. Western blot shows lysates of K562 human chronic myelogenous leukemia cell line and HepG2 human hepatocellular carcinoma cell line. PVDF membrane was probed with 2 µg/mL of Mouse Anti-Human HHEX Monoclonal Antibody (Catalog # MAB8377) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # HAF018). A specific band was detected for HHEX at approximately 37 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.
Detection of Human HHEX by Simple WesternTM. Simple Western lane view shows lysates of K562 human chronic myelogenous leukemia cell line, loaded at 0.5 mg/mL. A specific band was detected for HHEX at approximately 47 kDa (as indicated) using 20 µg/mL of Mouse Anti-Human HHEX Monoclonal Antibody (Catalog # MAB8377). This experiment was conducted under reducing conditions and using the 12-230 kDa separation system.

Hematopoietically-expressed homeobox protein (HHEX), also known as HEX, PRH and PRHX, is a 35-40 kDa member of the Homeobox family of transcription factors. Family members are distinguished by an evolutionarily conserved DNA-binding homeodomain of 60 amino acids (aa), which for HHEX spans aa 137-196. Human HHEX was initially isolated from hematopoietic tissue, and is present in several hematopoietic progenitors, where its expression is down-regulated during terminal cell differentiation. HHEX is also expressed in the anterior visceral endoderm during early mouse development, and in some adult tissues of endodermal origin, including liver, lung and thyroid. HHEX knockout in mice is embryonic lethal, with impaired forebrain, liver and thyroid development. Human HHEX is 270 aa in length, and over aa 111-270, shares 93% and 95% identity with mouse and rat HHEX, respectively.
