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.
Please check that this product meets your needs before purchasing. If you have any questions, special requirements or concerns, please send us an inquiry and/or contact our Support team ahead of purchase. Recommended alternatives for this product can be found below, as well as customer reviews and Q&As.

Our Abpromise guarantee covers the use of ab1423 in the following tested applications.
The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
|ICC||Use at an assay dependent concentration.|
|WB||1/2000. Detects a band of approximately 60-65 kDa. An additional non specific band at 35 kDa may be observed. Denatured whole cell extracts (prepare total cell extracts with 6M urea, 1% SDS, 150 mM NaCl, 25mM Tris ph8, and then sonicate for 10 seconds)and TBS based buffers with 0.5% Tween 20 are recommended.|
機能Binds the telomeric double-stranded TTAGGG repeat and negatively regulates telomere length. Involved in the regulation of the mitotic spindle. Component of the shelterin complex (telosome) that is involved in the regulation of telomere length and protection. Shelterin associates with arrays of double-stranded TTAGGG repeats added by telomerase and protects chromosome ends; without its protective activity, telomeres are no longer hidden from the DNA damage surveillance and chromosome ends are inappropriately processed by DNA repair pathways.
組織特異性Highly expressed and ubiquitous. Isoform Pin2 predominates.
配列類似性Contains 1 HTH myb-type DNA-binding domain.
ドメインThe acidic N-terminal domain binds to the ankyrin repeats of TNKS1 and TNKS2. The C-terminal domain binds microtubules.
The TRFH dimerization region mediates the interaction with TINF2.
翻訳後修飾Phosphorylated preferentially on Ser-219 in an ATM-dependent manner in response to ionizing DNA damage.
ADP-ribosylation by TNKS1 or TNKS2 diminishes its ability to bind to telomeric DNA.
Ubiquitinated by RLIM/RNF12, leading to its degradation by the proteasome. Ubiquitinated by a SCF (SKP1-CUL1-F-box protein) ubiquitin-protein ligase complex, leading to its degradation by the proteasome.
細胞内局在Nucleus. Cytoplasm > cytoskeleton > spindle. Chromosome > telomere. Colocalizes with telomeric DNA in interphase and metaphase cells and is located at chromosome ends during metaphase. Associates with the mitotic spindle.

Western blot using anti-TRF1 at 1/2000. A single band at 60-65 kD is detected. Western blot using anti-TRF1 at 1/2000. A single band at 60-65 kD is detected.
Cells transfected with a TRF1-GFP contruct. On the left: immunofluorescence with the anti-TRF1 antibody used at 1/300, with a Texas Red-conjugated secondary antibody. In the centre: fluorescence from the GFP. Right: merge of both images showing overlap of GFP fluorescence and antibody staining.
The cells in the first image are probably in a stage of the cell cycle where the signal is not so clear. In this image the antibody is shown to recognise the same signal but staining is shown as 20-30 spots (punctate foci).
