特記事項Our collaborator on this project has found that the antibody works poorly in WB.
Reproducibility is key to advancing scientific discovery and accelerating scientists’ next breakthrough.
Abcam is leading the way with our range of recombinant antibodies, knockout-validated antibodies and knockout cell lines, all of which support improved reproducibility.
We are also planning to innovate the way in which we present recommended applications and species on our product datasheets, so that only applications & species that have been tested in our own labs, our suppliers or by selected trusted collaborators are covered by our Abpromise™ guarantee.
In preparation for this, we have started to update the applications & species that this product is Abpromise guaranteed for.
We are also updating the applications & species that this product has been “predicted to work with,” however this information is not covered by our Abpromise guarantee.
Applications & species from publications and Abreviews that have not been tested in our own labs or in those of our suppliers are not covered by the Abpromise guarantee.

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.
Contains 1 SET domain.

Exposure time: 10 seconds
ab5517 recognises a band corresponding to the tagged CLLD8/SETB2 at approximately 120 kDa.
Abcam recommends using milk as the blocking agent. Abcam welcomes customer feedback and would appreciate any comments regarding this product and the data presented above.
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.
Right: Overexpressed CLLD8
Detection using indirect fluorescence of the signal corresponding to staining with anti-FLAG mouse antibody (top) and an antibody (ab5517) against CLLD8 (middle) in 293T cells. 293T cells were transfected with vectors for overexpression of flagged CLLD8 using Lipofectamine 2000 transfection procedure (Invitrogen). Cells were fixed 48 hours post-tra
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.

Predicted band size: 82 kDa
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.
