      DescriptionSMC™ Human Phospho-α-Synuclein (S129) High Sensitivity Immunoassay Kit
      OverviewThe SMC™ Human Phospho-α-Synuclein (S129) High Sensitivity Immunoassay Kit contains all reagents required to perform the assay. This assay takes advantage of a standard immunoassay workflow configured in a standard plate format. Assay protocols are similar to existing sandwich ELISA methods with two key differences: 1) Elution buffer disrupts the sandwich, separating the labeled detection antibody for quantification. 2) The Erenna® and SMCxPRO™ immunoassay systems detect analytes using Single Molecule Counting (SMC™) technology.
      Background InformationHuman α-synuclein, encoded by the gene SNCA, is a presynaptic neuronal protein that has been studied for its potential pathological link to neurodegenerative diseases, most notably Parkinson’s disease (PD), where this protein has been observed to undergo aberrant misfolding and aggregation within neurons. In recent years, there has been increasing evidence that phosphorylation of Serine-129 can be specifically observed in neuronal α-synuclein aggregations within PD patients, in a manner not seen in healthy brains. The SMC™ Human phospho-α-synuclein (S129) High Sensitivity Immunoassay Kit enables researchers to further their understanding of this protein as a potential neurodegenerative marker, by accurately measuring this analyte in human cerebrospinal fluid (CSF) and blood-based samples.
