General Notes
This product (Catalog No. DPABH-22334) is a rabbit-derived polyclonal antibody raised against human MN1, targeting the amino acid region 978–1320 of the protein. It has been affinity purified by Protein A. MN1 (Transcriptional activator MN1), which is mainly located in nucleus. Highest expression is observed in fetal brain and skeletal muscle, and adult skeletal muscle. MN1 protein can interact with Brg1/Brm related factor (BAF) complex containing Smarca4/Brg1 and stabilize it on chromatin, thus maintaining the expression of hematopoietic progenitor cell-like genes. Under normal physiological conditions, MN1 protein is mainly expressed in granulocyte monocyte progenitor cells (GMP) in hematopoietic system, which plays an important role in the development and function of hematopoietic cells, and it is involved in regulating cell proliferation, differentiation, apoptosis and embryonic development. MN1 protein is related to many diseases, especially in leukemia (PMID: 23049943). MN1 gene rearrangements such as t(12; 22)(p13; Q11) can produce MN1-TEL fusion protein, which combines the transcriptional activation domain of MN1 and the DNA binding domain of TEL(ETV6), and can stably occupy the TEL recognition sequence, hindering the combination of normal transcription regulatory factors, thus leading to leukemia. Overexpression of MN1 gene has also been proved to be one of the signs of poor prognosis in patients with acute myeloid leukemia (AML), and its expression level is high in AML patients with normal karyotype. The molecular weight of MN1 is 136 kDa.
DPABH-22334 is suitable for use in Western blot (WB) (1:500–1:3,000), IHC (1:50–1:500) applications.
DPABH-22334 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.
