ターゲット情報

  • 機能Histone methyltransferase involved in left-right axis specification in early development and mitosis. Specifically trimethylates 'Lys-9' of histone H3 (H3K9me3). H3K9me3 is a specific tag for epigenetic transcriptional repression that recruits HP1 (CBX1, CBX3 and/or CBX5) proteins to methylated histones. Contributes to H3K9me3 in both the interspersed repetitive elements and centromere-associated repeats. Plays a role in chromosome condensation and segregation during mitosis.
  • 組織特異性Ubiquitous. Highest expression in heart, testis and ovary.
  • 配列類似性Belongs to the histone-lysine methyltransferase family.
    Contains 1 MBD (methyl-CpG-binding) domain.
    Contains 1 pre-SET domain.

  • ICC/IF image of ab5517 stained MCF-7 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 ab5517 at 5ug/ml overnight at +4°C. The secondary antibody (green) was DyLight® 488 Goat anti Rabbit (ab96899) 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.

    Detection using indirect fluorescence of the signal corresponding to endogenous CLLD8 in 293T cells. Cells fixed using 4% formaldehyde, blocked with PBS containing 3% milk and 0.5% Triton X-100, incubated for 1 hour at 37 °C using a 1/50 dilution of antibody ab5517. Cells were then washed 3 times and incubated for 1 hour at 37 °C with a goat anti-rabbit secondary antibody (1/500 dilution) coupled to Alexa Fluor 555 (Molecular Probes). Following 3 more washes, cells were stained with DAPI and mounted with Vectashield.

  • Detection using indirect fluorescence of the signal corresponding to endogenous CLLD8 in 293T cells. Using Lipofectamine 2000 (Invitrogen), cells were transfected with either a control shRNA directed against luciferase (left, SiRluc) or a specific siRNA directed against CLLD8 (right). 48 hours post-transfection, cells were fixed, blocked, and incubated with a 1:50 dilution of ab5517 at 37 °C for 1 hour. Cells were then washed 3 times and incubated at 37 °C for 1 hour with a 1/500 dilution of goat anti-rabbit antibody coupled with Alexa Fluor 555 (Molecular Probes). Following 3 further washes cells were stained with DAPI and mounted with Vectashield.

    Antibody signals were extinguished when a specific RNAi was used. The few cells which retained a signal were presumably not transfected.

    Observed band size : 110 kDa (why is the actual band size different from the predicted?)
    Additional bands at : 22 kDa (possible non-specific binding),90 kDa (possible non-specific binding).
    ab5517 recognises a band corresponding to FLAG-tagged CLLD8/SETB2 at approximately 110 kDa in Sf21 cells infected by baculovirus expressing CLLD8/SETDB2 (lanes1-2). This is larger than the predicated band size (81 kDa) due to the addition of the FLAG tag.

    ab5517 does not detect a band in uninfected sf21 cells (lanes3-4) or following blocking studies using the immunizing peptide (lanes5-6).

    There appears to be a ladder of proteins recognised by ab5517 (lanes1-2), which could be attributed to degradation products.

Paraffin embedded human colon was incubated with ab5517 (1/50) for 30 minutes at room temperature. Antigen retrieval was performed by heat induction in citrate buffer pH6. ab5517 was tested in a tissue microarray (TMA) containing a wide range of normal and cancer tissues as well as a cell microarray consisting of a range of commonly used, well characterised human cell lines.

Thank you for your inquiry. I BLASTed the immunogen sequence of ab5517 against mouse and it only has 55% homology.  We generally say that anything with a greater than 85% homology would be expected to cross-react, so this is quite low.  This antibo...
