Cell Line Screening: Clonal Selection, Isolation, and Stability
Flow cytometry and cell sorting can be used to analyze and isolate cells for a particular phenotype. In cell line development, initial screening of transformed cells on a cell analyzer is followed by pool enrichment or single-cell sorting to isolate a stable, high-yielding production cell line. Flow cytometry is also used for monitoring cell line phenotype stability throughout its lifetime, and for assessing thawed cells from frozen master cell banks.

Efficacy Testing for Coronavirus Therapeutic Development
A significant challenge in therapeutic development is characterizing cellular immune response and identifying the key mediators of efficacy. Studying immunogenicity and pharmacokinetics / pharmacodynamics (PK/PD) in treatment groups can include antibody characterization and cell phenotyping.
Protein Profiling: Multiplex Immunoassays
Protein profiling in viral disease can yield markers for treatment efficacy, and characterizing the immunogenicity of therapeutics is critical to proving their safety and efficacy. Cytokine profiling is particularly important in COVID-19 therapeutic development.
Bio-Plex Multiplex Immunoassays for Cytokine & Chemokine Profiling
To characterize host response to coronavirus disease and help monitor the effectiveness of potential therapeutics, cytokines and chemokines can be quantitated from serum or other samples using Bio-Plex Immunoassay Panels, as recently described in Lancet (Huang C et al. 2020), in a study of clinical features of patients infected with COVID-19.
Bio-Plex Multiplex Immunoassays use Luminex magnetic beads for the quantitation of over 450 biologically relevant targets in a 12.5 µl sample: markers for inflammation, immune response, and more. Choose assays in premade or custom configurations, or develop your own assays for new targets.
Bioassay Development for Protein Therapeutics: Immunogenicity & PK/PD
Determining immunogenicity and PK/PD of protein therapeutics is a key step to assessing their safety and ADME. Bio-Rad has a large catalog of antibodies to many of the therapeutic antibodies known to modulate the immune system, providing the ability to assay anti-drug-antibody response.

Vector Copy Number: Dosing Regimens for Cell Therapies
If your therapeutic is cell-based, then there may be a need for accurate vector copy number (CNV) determination. CNV is an important characterization when trying to achieve ideal dosing, as it has implications in therapeutic efficacy and risk. The high-precision absolute quantification of ddPCR enables the detection of small-fold copy number changes, providing confidence in discriminating between integration events beyond 3 copies.
Droplet Digital PCR Copy Number Assays
Our ddPCR Copy Number Determination Assays offer high precision and resolution to easily discriminate between small changes in copy number, e.g. a 1.2-fold change in CNV from 5 to 6 copies:
