General description

CDT1 (Chromatin Licensing and DNA replication Factor 1) is an essential component of the cell cycle machinery. It plays an important role in insuring that there is only one round of DNA replication per cell cycle. CDT1 is a known substrate of Cdk2 and Cdk4 (Liu, E. 2004). It is presented in G1 of the cell cycle and is degraded as cells enter S phase (Liu, E. 2004). In higher eukaryotes, CDT1 is known to interact with Geminin, a protein that is degraded during mitosis, that inhibits it. CDT1 is marked for degradation by two E3 ligases: SCF complex and the CUL4-DDB1 complex (Sansam, 2006).


This antibody recognizes CDT1.


KLH-conjugated linear peptide corresponding to human CDT1.


Use Anti-CDT1 Antibody (Rabbit Polyclonal Antibody) validated in WB to detect CDT1 also known as DNA replication factor, Double parked homolog.

Western Blot Analysis: A 1:1,000 dilution from a previous lot detected CDT1 in C2C12, Hek293, HeLa, HepG2, Huvec, Jurkat, L6, mouse brain, NIH/3T3, PC3, and RAW264.7 cell lysates.


Evaluated by Western Blot in HeLa cell lysate.
Western Blot Analysis: A 1:1,000 dilution of this antibody detected CDT1 in 10 µg of HeLa cell lysate.

Target description

~60 kDa

Physical form

Rabbit polyclonal serum with 0.05% sodium azide.

Storage and Stability

Stable for 1 year at -20°C from date of receipt.
Handling Recommendations: Upon first thaw, and prior to removing the cap, centrifuge the vial and gently mix the solution. Aliquot into microcentrifuge tubes and store at -20°C. Avoid repeated freeze/thaw cycles, which may damage IgG and affect product performance.

Analysis Note

Spatial management of stress-induced protein aggregation is an integral part of the proteostasis network. Protein modification by the ubiquitin-like molecule NEDD8 increases upon proteotoxic stress and it is characterised by the formation of hybrid NEDD8/ubiquitin conjugates. However, the biological significance...

Inhibition of NEDD8-activating enzyme (NAE) has emerged as a highly promising approach to treat cancer through the adenosine sulfamate analog MLN4924. Here, we show that selective pressure results in HCT116 colorectal carcinoma cells with decreased MLN4924 sensitivity and identify a...

Effective DNA replication is critical to the health and reproductive success of organisms. The six MCM2-7 proteins, which form the replicative helicase, are essential for high-fidelity replication of the genome. Many eukaryotes have a divergent paralog, MCM9, that was reported...

Infection by the autonomous parvovirus minute virus of mice (MVM) induces a vigorous DNA damage response in host cells which it utilizes for its efficient replication. Although p53 remains activated, p21 protein levels remain low throughout the course of infection....
