We provide a seamless transition from initial dye titration and concentration optimization to high-speed sorting, ensuring high-purity fractions are ready for immediate downstream molecular or cellular applications.
Cancer Stem Cell Side Population (SP) Dye Exclusion Detection Service
Creative Biolabs provides a high-precision functional assay service that identifies and isolates cancer-initiating cell fractions based on dye-efflux kinetics. We offer researchers a complete solution-from protocol optimization for specific cell lines to the delivery of high-purity sorted fractions for downstream molecular analysis. By partnering with us, our clients gain reliable, reproducible data on the "stemness" of their tumor models, enabling a deeper understanding of resistance mechanisms and significantly enhancing the accuracy of preclinical drug screening programs.

Introduction to CSC Side Population Assay
The side population assay is a functional method for identifying specialized cell fractions based on their ability to efflux Hoechst dye via ATP-binding cassette transporter proteins. Extensive scientific appraisal has validated the SP as a reservoir for experimental resistance and tumor initiation in laboratory models. Functional SP analysis often provides a more robust characterization than surface markers alone by identifying truly active stem-like cells. Creative Biolabs provides this gold-standard assay to ensure your research targets the core of tumor propagation.

Customer Reviews
-
Unmatched Resolution in CRC Models
Using Creative Biolabs' SP service in our colorectal cancer research has significantly improved our ability to track resistance in cell cultures. Their use of pharmacological inhibition provided the cleanest and most reproducible gating we've seen compared to standard assays. - Dr. A***n. L. -
Excellent for Laboratory Cell Systems
The dissociation and quenching protocols used by Creative Biolabs facilitated our study on glioblastoma stem-like cells. They successfully excluded high-debris interference that previously made our in-house SP analysis impossible. - Prof. S***a. K.
FAQs
Can the SP assay be performed on any cell line?
While highly versatile, SP prevalence varies by model. We offer a pilot titration service to determine the baseline SP fraction in your specific laboratory cell lines before beginning full-scale experiments.
How do you ensure the SP isn't just dead cells or debris?
We utilize mandatory viability gating and a specialized quenching protocol to eliminate non-specific surface binding, ensuring all reported SP cells are viable and functionally active for research.
