Moreover, it can be expected that the CCS and GPX1 antibodies have a high affinity for their respective antigens and may, therefore, give stronger signals than the CCS and GPX1 CyDye spot signals.1D‐WB analyses of CCS and GPX1 were also made on a randomly selected set of platelet samples from AD patients (n = 15) and controls (n = 15) for further validations. This evidence concerns the gene CCS and Alzheimer disease.
