Cyclin/CDK Activity Profiling Service for Cell Cycle Transition
Creative Biolabs provides a robust analytical framework to solve complex hurdles in cell cycle research. We move beyond static protein measurements to deliver deep insights into biochemical activity thresholds governing division or quiescence. Our platform precisely maps restriction point (R-point) passage and evaluates how candidates interact with active kinases versus the "p21-high" reservoir driving resistance. By providing kinetic resolution, we distinguish true arrest from transient delays, ensuring high-fidelity data for developing selective cyclin-dependent kinases (CDKs) inhibitors and navigating therapeutic decision-making.

Introduction of Cyclin/CDK Activity Profiling
CDKs are the master oscillators of the eukaryotic cell cycle. Historically viewed as binary switches, recent research has redefined cell cycle commitment as a precise biochemical threshold. It is now established that CDK activity levels, specifically CDK2, must cross a critical threshold to trigger the R-point. Furthermore, p21 serves as a "memory" molecule, where maternal stress determines the proliferative fate of daughter cells. Creative Biolabs utilizes these high-end insights to provide profiling that ensures therapeutic leads are effective across heterogeneous and adapted populations.
Precision Kinetic Profiling: Our Comprehensive Cyclin/CDK Solutions
At Creative Biolabs, we offer a comprehensive suite of profiling technologies that span the entire CDK family, from traditional cell cycle regulators to the most recent transcriptional and "dark" kinases. Our offerings are tailored to provide physiological relevance and high-throughput efficiency.
Real-Time CDK2 Activity Threshold Sensing
Utilizing the latest DHB-based ratiometric sensors, we offer live-cell imaging to determine if your leads can prevent cells from crossing the G0/G1 commitment threshold. This provides >95% accuracy in predicting proliferative fate compared to standard endpoint assays.
Trans-generational "Memory" Profiling
We offer a unique tracking system to evaluate how p21-induced quiescence is inherited by daughter cells. This service is essential for projects targeting the prevention of cancer cell dormancy and minimal residual disease.
Transcriptional CDK Panels
Our portfolio includes high-resolution activity assays for CDK7, CDK8, CDK9, and CDK12/13. We measure RNA polymerase II phosphorylation and elongation rates to characterize transcriptional inhibitors.
Selectivity Heat-Mapping
We provide a comprehensive screen against a panel of 20+ human CDKs. This allows for the immediate identification of off-target effects, ensuring your lead compounds possess the specificity required for safe clinical progression.
Cellular Adaptation & Stress Modeling
For clients working on cyclin E-overexpressing tumors, we offer "proliferative crisis" simulation models to study drug efficacy in adapted cancer cell populations.

FAQs
What is the advantage of live-cell imaging over standard western blotting?
Our live-cell imaging provides single-cell kinetic traces, capturing the exact moment of kinase activation that static assays miss.
Is it possible to request profiling for non-human CDK orthologs?
Yes. We offer validated profiling services for mouse, rat, and non-human primate complexes for cross-species comparison.
How do you handle cells that enter a quiescent (G0) state?
We use ratiometric sensors to distinguish between "CDK2-low" and "CDK2-high" states in real-time.
