細胞内局在
TRF2: Nucleus. Chromosome > telomere. Colocalizes with telomeric DNA in interphase cells and is located at chromosome ends during metaphase. TRF1: 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. -

Predicted band size: 50 kDa
Observed band size: 80 kDa why is the actual band size different from the predicted?Anti-TERF antibody [TRF-78] (ab10579) staining at 4 ug/ml, shown in green. In Western blot, ab10579 was shown to bind specifically to TERF. First, samples were run on an SDS-PAGE gel then transferred onto a nitrocellulose membrane. Membranes were blocked in 5 % milk in TBS-0.1 % Tween$®$ 20 (TBS-T) before incubation with primary antibodies overnight at 4 °C. Blots were washed four times in TBS-T, incubated with secondary antibodies for 1 h at room temperature, washed again four times then imaged. Secondary antibodies used were Goat anti-Mouse IgG H&L 800CW at 1/20000 dilution

Immunocytochemistry/ Immunofluorescence analysis of HeLa (Human epithelial cell line from cervix adenocarcinoma) cells labeling TRF1 and TRF2 with ab10579. Cells were fixed and permeabilized with 4% paraformaldehyde followed by 0.5% Triton™ X-100. Fixed cells were stained with 10 μg/mL Anti-TRF2 + TRF1 antibody [TRF-78]. The antibody was developed using Goat Anti-Mouse IgG, Cy3 conjugate. Cells were counterstained with DAPI (blue) to stain nuclei.

Immunofluorescent imaging of human cells (U2OS) with ab10579 confirms the specificity of this antibody. A few intense nuclear foci are seen in interphase cells, corresponding to telomeric localisation. The complete absence of background nuclear or cytoplasmic staining confirms the specificity of this antibody. This image is in exact agreement with numerous published reports.
IF was performed with a standard paraformaldehyde technique (fixed in PBS buffered PFH 4% for 5 minutes, permeabilised with 0.5% triton-PBS for 5 minutes, blocked with 5% milk / 0.2% tween for one hour. Primary antibody used at 1/100 in 5% milk / 0.2% TWEEN for one hour, secondary antibody for 30 minutes. All blocking and incubation steps carried out at 37 degrees. Nuclei are visualised using Hoechst stain.

ab10579 at 1/500 staining human HeLa (Human epithelial cell line from cervix adenocarcinoma) cells by ICC/IF. The cells were parafomaldehyde fixed and blocked with BSA prior to incubation with the antibody for 45 minutes. An Alexa Fluor® 555 conjugated donkey anti-mouse antibody was used as the secondary.
