Sall4 Antibody #5850
|W||H (Mk)||Endogenous||80, 142||Rabbit|
Reactivity Key: H=Human Mk=Monkey
Species cross-reactivity is determined by western blot. Species enclosed in parentheses are predicted to react based on 100% sequence homology.
Specificity / Sensitivity
Sall4 Antibody recognizes endogenous levels of total Sall4 protein, isoforms A and B. This antibody may also detect other Sall4 isoforms.
Source / Purification
Polyclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding to residues near the carboxy terminus of human Sall4 protein. Antibodies are purified by protein A and peptide affinity chromatography.
Members of the SALL gene family encode putative zinc finger transcription factors highly expressed during development (1). Sall4 is expressed very early in development with other pluripotency regulators, such as Oct-4 and Nanog (2). Recent studies suggest Sall4 works as a master regulator that controls its own expression and the expression of Oct-4 in a transcriptional regulation feedback loop governing stem cell pluripotency and stem cell fate (2,3). Immunohistochemical studies indicate that Sall4 is a sensitive and specific diagnostic marker for primary germ cell tumors and yolk sac tumors (4,5). Research studies have shown that Sall4 is constitutively expressed in acute myeloid leukemia (AML) and is a probable effector of the Wnt/β-catenin signaling pathway in this disease (6). In addition, mutations in Sall4 have been implicated in human malformation syndromes including Duane-radial ray syndrome (Okihiro syndrome) and Acro-renal-ocular syndrome (7).
