Trace cell cycle progression in live cells non-invasively
The Cell Cycle-Chromobody® visualizes the proliferating cell nuclear antigen (PCNA).
This nanoprobe consists of anti-PCNA VHH fused to a fluorescent protein. The Cell Cycle-Chromobody enables you to screen compounds such as cancer drugs for effects on the cell cycle and toxicity in one experiment. You can utilize the Cell Cycle-Chromobody for high content assays (HCA) in early drug development and validation as well as in basic research.

PCNA is the homotrimeric ringshaped protein that encircles the DNA and acts as a stationary loading platform for multiple, transiently interacting factors participating in various DNA transactions. As an essential cellular component, PCNA is highly conserved from yeast to man.
In eukaryotic cells, PCNA plays a key role in DNA replication, repair, cell cycle regulation, and post-replicative transactions like DNA methylation and chromatin remodelling.
