RarePlex Panel Kits
Circulating Tumor Cell Assays for Research
The RarePlex Panel Kit product line includes immunofluorescence Panel Kits and Developer Kits for circulating tumor cell (CTC) characterization, including enumeration, and specific kits include additional biomarkers for in-depth phenotypic characterization.
RarePlex Panel Kits are highly validated circulating tumor cell assays designed to work with the AccuCyte® Sample Preparation System, automated slide staining systems, and CyteFinder® Instruments.
Developer Kits are single channel kits and enable you to keep up with the pace of discovery. In order to provide you with assay flexibility, Developer Kits were designed to allow the addition of 1-2 biomarkers of your choice to a Panel Kit.

RarePlex Panel Kits
RarePlex Panel Kits are designed to work the RareCyte platform for circulating tumor cell analysis and are rigorously validated for sensitivity, specificity, and precision.
Enumeration Panel Kits include markers for circulating tumor cell identification and are performed on a Ventana or Leica automated slide staining system. With a 3-channel Panel Kit, you have the flexibility to create custom assays by adding up to two biomarkers with Developer Kits.
For in-depth phenotypic characterization, RareCyte offers Panel Kits with additional biomarkers such as HER2/ER and ARv7. With the ARv7 Panel Kit, you can choose to add an additional biomarker of your choice with a Developer Kit.

RarePlex Developer Kits for CTC Assay Development
RarePlex Developer Kits are designed to address cancer heterogeneity by enabling custom circulating tumor cell assay development for disease or assay-specific biomarker expression by circulating tumor cells. Developer Kits enable the addition of up to two biomarkers-of-interest to Panel Kits.
Keep your research current with the flexibility afforded by Developer technology.
