Figure 3From: Characterization of the postsynaptic protein neurogranin in paired cerebrospinal fluid and plasma samples from Alzheimer’s disease patients and healthy controlsAnalysis of cerebrospinal fluid neurogranin storage stability. Normalized cerebrospinal fluid neurogranin (Ng) concentrations in samples without (A) or with (B) the addition of a stabilizing agent. Samples were kept at room temperature (RT), 4°C or −20°C for between 1 and 7 days before transfer to storage at −80°C pending analysis. Samples were normalized to day 0, with or without stabilizer.Back to article page
