How to Perform a Progenitor Cell Assay (PCA) - An Alternative to All Methylcellulose CFU Assays
- A fluorescence, CFU-equivalent assay for cell processing laboratories.
- No colony counting required.
- Transforms the subjective CFU assay into an instrument-based, quantitative assay.
- Incorporates the same growth factor cocktails used in MethoCult® reagents for direct assay-to-assay comparisons and correlation.
- Non-subjective, instrument-based and quantitative.
- Results in 7 days.
- Faster, easier and more cost effective to use than any traditional CFU assay, even using automated colony counting.
- Complete assay kit; includes everything needed to culture and obtain results.
- Permitted by FDA and AABB.
The table below shows the HemoFLUOR™ PCA assays that can replace any methlcellulose, colony-forming unit (CFU) reagent from any competitor. PLEASE NOTE that HemoFLUOR™ PCA incorporates Suspension Expansion Culture™ (SEC™) Technology to replace dispensing error-prone methylcellulose with reagents that use normal pipettes.

(#) denotes that the Preferred Cell Systems™ formulation of this product includes TPO that stimulates the production of megakaryopoiesis. MethoCult™ and other competitor formulations of this specific product do not include TPO, do not stimulate the production of megakaryocytes and therefore do not detect the CFC-GEMM stem cell population.
- Incorporates the measurement of non-fluorescent Resazurin (alimaBlue™) to fluorescent resorufin in an oxidation/reduction reaction that occurs only in live cells. The amount of fluorescence (relative fluorescence units, RFU) is dependent on the metabolic status of the cells and therefore is not only a measure of metabolic viability, but cell proliferation or inhibition.
- After culture, add 10μL of reagent, mix and measure signal between 30 minutes and 4 hours in a fluorescence plate reader.
- Uses a plate fluorometer or multimode plate reader to measure fluorescence with an excitation filter 560nm and an emission filter of 590nm.
