Flow Cytometry Testing & Cell Sorting Services for Research

Flow cytometry is a powerful tool for characterizing cell populations, evaluating protein expression, and isolating specific cells for downstream research applications. ABS Bio provides both analytical flow cytometry and cell sorting services to support cell line development, translational research, immunology studies, therapeutic development, and biomarker discovery programs.

Using cell, blood, and tissue samples supplied by clients, generated through our cell culture facility, or sourced through ABS Bio’s biospecimen network, our team can analyze cellular characteristics, assess target expression, evaluate antibodies and reagents, and isolate populations of interest for further study. Whether your project requires phenotypic characterization, transfection assessment, immune profiling, antibody validation, or single-cell isolation, ABS Bio provides flexible flow cytometry and sorting solutions tailored to your research objectives.

We are able to characterize up to eight targets at a time. Our facility can characterize engineered cell lines, dissociated tissues, or simply profile cell lines in your inventory. Our services include:

• Verification of cell lines
• Confirmation of differentiation following induction experiments
• Characterization of dissociated tumor cells or blood
• Measure transfection efficiency using GFP or a unique target
• Examine fluorescence intensity of surface targets
• Surface receptor density assays

Our team can evaluate your flow cytometry antibodies to provide a quality evaluation of their effectiveness, efficiency, and performance.

• Compare efficiency of new lot to a previous lot or commercial antibody
• Titrations for working concentration determination
• Selection of the best commercial antibody option for your project

At ABS Bio, we can help extend your laboratory by performing gene therapy or cytotoxic assays to test your antigen, reagent, therapeutic, or genetic manipulation of interest. Our services include:

• Immunophenotyping and target expression
• Apoptosis Assays
• Characterization of cell behavior

• Isolate a population of interest from dissociated tumor cells or a heterogenous cell line
• Create a pooled GFP+ transfected cell line
• Purify a partially engineered cell pool

• Quickly perform limiting dilution assays
• Generate clonal cell lines
• Measure the fluorescence intensity of a target for each individual cell
• Improve monoclonal antibody discovery and production
• Prepare cells or a specific population for downstream single-cell analysis
