Advantages of Graphene Biosensors for Human Stem Cell Therapy Potency Assays

Figure 1

Biosensors for potency assay simplification. Traditional potency assay measurement technologies include (a) Protein expression via Sodium Dodecyl Sulphate-PolyAcrylamide Gel Electrophoresis (SDS-PAGE), (b) Gene expression via quantitative Real Time Polymerase Chain Reaction (qRT-PCR), (c) Live cell flow cytometry via Fluorescence-Activated Cell Sorting (FACS) analysis, or (d) Enzyme-Linked Immunosorbent Assay (ELISA) for antibody targets. These are typically multistep procedures requiring more time and expertise than needed for application of (e) dedicated biosensors tailored for specific target analytes.
