General Notes
This product (Catalog No. DPABH-22269) is a rabbit-derived polyclonal antibody raised against human FBXW7, targeting the amino acid region 1–227 of the protein. This antibody exhibits cross-reactivity with Human FBXW7 from mouse. It has been affinity purified by Protein A. FBXW7, also named as FBW7, FBX30, SEL10 and hAgo, is a substrate recognition component of a SCF (SKP1-CUL1-F-box protein) E3 ubiquitin-protein ligase complex which mediates the ubiquitination and subsequent proteasomal degradation of target proteins. It probably recognizes and binds to phosphorylated target proteins. FBXW7 is involved in the degradation of cyclin-E, MYC, NOTCH1 released notch intracellular domain (NICD), and probably PSEN1. FBXW7 is a general tumor suppressor in human cancer (PMID: 17909001). FBXW7 has 3 isoforms (α/β/γ) with the calculated molecular mass of 80 kDa, 70 kDa and 66 kDa, and apparent molecular mass of 100-110 kDa and 66-75 kDa (PMID: 31346036/PMID: 22864569). K48 autoubiquitination is consistent with maintenance of ubiquitinated FBW7 (Ub-FBW7, 200 kDa)(PMID: 32353058).
DPABH-22269 is suitable for use in Western blot (WB) (1:500–1:2,000), IHC (1:50–1:500) applications.
DPABH-22269 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.
