Anti-CDC6 Antibody, Rabbit Polyclonal, Affinity Purified


SKU: 70-133 Research Area: Applications:


CDC6 (Cell Division Control Protein 6 homolog) (human; 560 aa, 62.7 kDa) is involved in the initiation of DNA replication. Also participates in checkpoint controls that ensure DNA replication is completed before mitosis is initiated.


Subcellular location: The protein is nuclear in G1 and cytoplasmic in S-phase cells.


Purification: The antiserum was first adsorbed with GST conjugated agarose column and then the antibody in the pass-through fractions were purified with GST-CDC6 conjugated column.



Reactivity: human, mouse, rat

Form: 1 mg/ml in PBS with 50% glycerol. Filter-sterilized. Azide and carrier free

Immunogen: Recombinant GST-human CDC6 (1-326 amino acids) expressed in E. coli

Validation: Specificity of reaction has been validated with siRNA in WB (Ref.5 & 7)

Storage: Sent at 4℃ and upon arrival, spin-down and store at -20℃



Western blotting (1/1,000~3,000)


Chromatin Immuno-Precipitation (assay dependent)

Immunofluorescence staining (1/200)

Confocal microscopic analyses of localization of CDC6 proteins in HeLa cells in G1 or early S phase. Cells in mid to late G1phase or hydroxyurea-treated early S phase were fixed with formaldehyde directly or after extraction with Triton X-100 and then immunostained with anti-CDC6 or control non-immune antibody (AF green). The samples were further treated with propidium iodide for DNA staining (PI; red).



Fig.4 Immunofluorescence staining of CDC6 in MEF cells

MEFs (mouse embryonic fibroblasts ) from embryonic day 14.5 mouse embryos were fixed with 10 % formalin at room temperature (RT) for 10 min, permeabilized with ice-cold methanol on ice for 10 min, and treated with 2 % BSA/PBS at RT for 1h. The cells were reacted with anti-cdc6 antibody (1:200) at 4°C overnight and then with AF-555-conjugated goat anti-rabbit IgG antibody (1:1000) at RT for 1h. Chromosomal DNA was counterstained with 3.3 μM Hoechst 33342. Note that CDC6 abundantly localizes in nuclei of the cells at G1 and early S phase.
