Quantitative Analysis of Amyloid Burden

Images were obtained from an average of 3 sections per mouse for IHC and IF. For IHC stains, slides were scanned on the NanoZoomer 2.0-HT system (Hamamatsu Photonics) at 20x. Images were further processed using NDP viewing software (Hamamatsu Photonics) and Fiji software version 1.51 (National Institutes of Health). The sections were converted into 8-bit images followed by a selection of cerebral cortex and hippocampus using tissue landmarks. An appropriate threshold number (based on the preliminary analysis avoiding floor/ceiling effects) was applied consistently to highlight the majority of amyloid plaques ensuring no artifacts were incorporated in the quantification. Particles were analyzed and collated numbers were collected to calculate the mean amyloid burden between groups using GraphPad Prism software. For IF (Iba1 and GFAP) stains and slides were scanned on Leica Thunder imager 3D assay at 20x. Images were further processed using Fiji software as previously described.

Cells were grown to mid-logarithmic phase and fixed with 4% formaldehyde in 0.1 M potassium phosphate buffer. Cells were then converted to spheroplasts using 0.1 M potassium phosphate buffer containing 1.2 M sorbitol and 500 μg of zymolyase. Spheroplasts were washed in 2× SSC buffer and incubated overnight at 37 °C with Cy3-labeled oligonucleotide probe (5′-Cy3-ATG CTC TTG CCA AAA CAA AAA AAT CCA TTT TCA AAA TTA TTA AAT TTC TT-3′) that is complementary to the 5′ portion of ITS1 (Faza et al., 2012). DNA was stained with 0.5 μg/ml DAPI. Cells were visualized using THUNDER Imager 3D Assay (Leica, Germany) equipped with a HCX PL-APO Fluotar 100×/1.44 NA oil immersion objective (Leica, Germany). Images were acquired with a fitted digital sCMOS camera and LAS X premium software (Leica, Germany).

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
