PFC samples collected immediately following decapitation under anesthesia were lysed in ice-cold lysis buffer containing protease inhibitor cocktail (1860932, ThermoFisher scientific, Waltham, MA) and protein concentration was determined by bicinchoninic acid (BCA) assay (MilliporeSigma St. Louis, MO). Protein was electrophoretically separated on a SDS PAGE gel and transferred to a nitrocellulose membrane. Blots were incubated in the appropriate primary antibody specific for C3 (sc-28294, Santa Cruz Biotech, Dallas, Texas), C3aR (sc-133172; Santa Cruz Biotech),VCAM-1 (114441-1-AP; Proteintech, Rosemont, IL), ICAM-1 (10831-1-AP; Proteintech), β-tubulin (2146, Cell Signaling, Danvers, MA) or β-actin (4967, Cell Signaling); and developed with the ECL Plus Western Blotting Detection System (GE Healthcare). Optical densities of the bands were analyzed using ImageJ software (NIH). For analysis, protein levels were normalized to β-tubulin or β-actin levels then expressed as a fold change of that in control animals.

Immunohistochemistry and Western Blot Analysis

IHC staining was performed as previously described.53 (link) Tissue microarrays were scanned with a digital slide scanner (Pannoramic MIDI, 3D HISTECH) after staining and processed with Pannoramic viewer software. Intensity of staining in cells was automatic calculated by Quant center software. Histochemistry score (H-score) was acquired according to the formula: H-score = (percentage of weak intensity area ×1) + (percentage of moderate intensity area ×2) + (percentage of strong intensity area ×3). Western blot analysis was conducted as previously described.54 (link) The following primary antibodies were used: ICAM1 (10831-1-AP, Proteintech), phospho-IκBα (#2859, CST), NF-κB p65 (#8242, CST), phospho-NF-κB p65 (#3033, CST), ALPK1 (GTX01077, GeneTex) and GAPDH (10494-1-AP, Proteintech).

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.
