Overview
Drug resistance remains a critical barrier to effective cancer therapy. Reliable drug-resistant cell models are essential for understanding the molecular mechanisms of resistance, identifying biomarkers, and evaluating novel therapeutic strategies. Our Drug-Resistant Cell Model Construction service provides customized, high-quality cell lines that recapitulate acquired resistance to specific targeted agents or chemotherapeutics.
We employ two primary approaches validated in the literature: continuous or stepwise drug exposure, which mimics clinical resistance development, and CRISPR/Cas9-based engineering to introduce or knock out resistance-driving mutations. Both methods yield stable, characterized models that can be used for mechanism-of-action studies, combination therapy screening, and resistance reversal assays.
Each project begins with a detailed consultation to define the parental cell line, drug of interest, resistance target, and desired validation endpoints. Our team ensures that final models are thoroughly characterized for resistance stability, cross-resistance profile, and phenotypic consistency.
Our Offer
Custom Drug Exposure Regimens
Stepwise or continuous drug escalation protocols tailored to your timeline and drug class, producing stable resistant cell populations.
CRISPR-Based Resistance Engineering
Precise introduction of resistance-associated point mutations, knockouts, or gene expression changes using CRISPR/Cas9 technology.
Comprehensive Phenotypic Characterization
Full resistance profile including IC50 shifts, growth kinetics, resistance index, and stability assessment over extended culture.
Workflow
Deliverables
| Parameter | Typical Project Scope |
|---|---|
