Formalin-Fixed Paraffin-Embedded (FFPE) human brain tissue was sectioned to 5 μm and mounted on microscope slides. The sections were dewaxed at 60 °C for 30 min and then transferred into HistoChoice (Sigma) for 2 washes for 5 min each. Sections were then moved into 100%, 95% and 70% ethanol for rehydration followed by three washes in PBS. For C3 staining, sections underwent antigen retrieval in M6 buffer (2.1% citric acid monohydrate, 2.94% tri-sodium citrate in dH2O, pH 6) at 95 °C for 10 min.
Sections were then blocked in blocking buffer containing 10% normal goat serum (NGS), 0.4% Triton X-100 (Sigma) in PBS for 1h at room temperature. The following primary antibodies were used: C3d (Dako A0063, rabbit 1:600), GFAP (Dako Z0034, rabbit, 1:500), GFAP (Sigma G3893, mouse, 1:400) and SPARC (R&D MAB941, mouse, 25 ug/mL).

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.
