Abstract
A Fluorescence-Linked Immunosorbent Assay (FLISA) targeting β-cross-sheet α-synuclein protein, a crucial marker in Parkinson’s Disease (PD), was assessed using in vitro assay with a rotenone-induced PD cellular model. The study aimed to evaluate FLISA’s applicability with the inhouse developed labelled polyclonal antibody (pAb). Results are promising the competitive assay successfully distinguished misfolded α-synuclein in SH-SY5Y cells. Quantitative analysis revealed a direct correlation between competitive antigen concentration and decreased fluorescence, showcasing FLISA’s sensitivity. Controls exhibited maximal fluorescence, confirming the absence of misfolded proteins, while rotenone exposed cells displayed reduced fluorescence, suggesting their presence. This approach enhances PD understanding and supports potential interventions.
