General Notes
This product (Catalog No. DPABH-04438) is a rabbit-derived polyclonal antibody raised against human MSI1, targeting the amino acid region 1–83 of the protein. It has been affinity purified by Protein A. Musashi1 (Msi1) is an RNA-binding protein expressed in neural progenitor cells and neural stem cells. The gene encoding human Msi1 encodes a 362 amino acid protein. In murine embryonic neural progenitor cells, Msi1 localizes to the cytoplasm and is downregulated during differentiation. Msi1 binds to NUMB, which encodes a membrane-associated antagonist of Notch signaling. Msi1 appears to function in the proliferation and maintenance of stem cell populations of the central nervous system. In addition to its usefulness as a marker for neural progenitor cells in normal human brains, Msi1 is also a marker for human gliomas. In rats, Msi1 is expressed in Sertoli cells of the testis and granulosa cells of the ovary.
DPABH-04438 is suitable for use in Western blot (WB) (1:1,000–1:6,000), IHC (1:50–1:500) applications.
DPABH-04438 is supplied as a liquid formulation in PBS with 0.02% sodium azide and 50% glycerol, pH 7.3. For long-term storage, keep at −20 °C. For short-term use, store at 2–8 °C. Avoid repeated freeze–thaw cycles to maintain antibody integrity and performance.
