应用 Ab评论 说明
ICC/IF Use a concentration of 10 µg/ml.
WB 1/10000 - 1/50000. Detects a band of approximately 180 kDa (predicted molecular weight: 183 kDa).
IHC-P 1/100 - 1/250. Perform heat mediated antigen retrieval with citrate buffer pH 6 before commencing with IHC staining protocol.
  • 应用说明Is unsuitable for Flow Cyt or IP.
  • 靶标

    • 功能Control of topological states of DNA by transient breakage and subsequent rejoining of DNA strands. Topoisomerase II makes double-strand breaks. Indirectly ivolved in vitamin D-coupled transcription regulation via its association with the WINAC complex, a chromatin-remodeling complex recruited by vitamin D receptor (VDR), which is required for the ligand-bound VDR-mediated transrepression of the CYP27B1 gene.
    • 序列相似性Belongs to the type II topoisomerase family.
    • 翻译后修饰Phosphorylated upon DNA damage, probably by ATM or ATR.
    • 细胞定位Cytoplasm. Nucleus > nucleolus.

    • ICC/IF image of ab109524 stained HeLa cells. The cells were 4% Formaldehyde fixed (10 min) and then incubated in 1%BSA / 10% normal goat serum / 0.3M glycine in 0.1% PBS-Tween for 1h to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab109524, 10µg/ml) overnight at +4°C. The secondary antibody (green) was ab96899, DyLight® 488 goat anti-rabbit IgG (H+L) used at a 1/250 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (red) at a 1/200 dilution for 1h. DAPI was used to stain the cell nuclei (blue) at a concentration of 1.43µM.
