WebAbstract. BACKGROUND: Peanut allergy is a life-threatening condition; there is currently no cure. While whole allergen extracts are used for specific immunotherapy for many allergies, they can cause severe reactions and even fatalities in peanut allergy.

WebIn this work, we probed HLA-X-idiotype-TCR binding and designed enhanced-reactive pHLA-TCR antigens using an in silico mutagenesis approach which we functionally validated by cell proliferation assays and flow cytometry. WebCFSE is a first-generation cell proliferation tracker that covalently labels long-lived intracellular molecules with the fluorescent dye, carboxyfluorescein. When CSFE-labeled cells divide, each progeny cell also contains CFSE. Each generation exhibits a decrease in fluorescence, which can be measured via flow cytometry.
WebApr 4, 2024 · Conventional proliferation assays are employed in a range of evaluations, such as: (i) DNA synthesis through radioactive tracer (3H-thymidine) or nucleotide analogue (bromodeoxyuridine; BrdU) incorporation, or DNA content; (ii) the activity of mitochondrial enzymes that reduce tetrazolium salts such as MTT …
