CMMC Assay

Menarini Silicon Biosystem’s new Circulating Multiple Myeloma Cell (CMMC) Assay captures and enumerates CMMCs from peripheral blood and provides a unique, non-invasive tool to study multiple myeloma and precursor disease states as well as monitor disease progression in clinical research studies.

Leveraging the gold-standard CELLSEARCH® technology, the CMMC Assay immuno-magnetically captures CD138+ plasma cells using anti-CD138 antibodies bound to ferrofluid nanoparticles. CMMCs are identified by CD38 staining, and other white blood cells are excluded using a CD19/CD45 staining cocktail.

Assay Reagent Function
Anti-CD138 Antibody Ferrofluid Plasma Cell Capture
Anti-CD38-PE Antibody Inclusion Marker for Plasma Cells
DAPI Nuclear Dye for Detection of All Cells
Anti-CD19/CD45-APC Antibody Cocktail Exclusion Marker for Non-PC Leukocytes

CMMC Phenotype: CD138+, CD38+ and CD45/19-
Multi Epitope & Monoclonal Anti-CD38 Antibodies: Reduces potential interference from CD38-targeted therapies

Benefits

  • Non-invasive enumeration of Multiple Myeloma (MM) cells using a simple blood draw, as opposed to the standard of a painful bone marrow biopsy
  • Liquid biopsy assay with high specificity and sensitivity (100-fold increase compared to FACS)
  • Cells can be cryopreserved for downstream applications
  • Enables monitoring of MM precursor states (such as MGUS and Smoldering Myeloma) and Multiple Myeloma disease progression to investigate disease biology in clinical research studies
