Check if the same lab product or an alternative is used in the 5 most similar protocols
EFV was purchased from Toronto Research Chemicals Inc., Ontario, Canada. The PK and Pefabloc (protease inhibitor) were purchased from Roche, Germany. All other reagents/chemicals were purchased from Sigma-Aldrich, USA. The PrP monoclonal antibody (mAb) 4H11 used in this study to detect PrP has been previously described [42 (link)]. The antibodies anti-Cyp46A1 (ab82814, Abcam, USA), anti-flotillin-1 (610,821, Mouse BD Transduction Laboratories) and anti-β-actin (Cell signaling) were used. Secondary antibody conjugated with peroxidase, goat anti-mouse HRP, was obtained from Jackson Immuno Research, USA.

Cholesterol Metabolism Regulation

27-Hydroxycholesterol was provided by American Santa Cruz, and 27-OHC (10 mg) was completely dissolved in a suitable amount of ethanol, then divided equally in centrifuge tubes, with nitrogen gas blowing dry, and finally preserved at −80°C. The 27-OHC working solution contains 0.16% ethanol (v/v). Filipin III was from Cayman Chemical (#70440, Ann Arbor, MI, United States). Primary antibodies for Western blot included mouse anti-ABCA1 (Abcam, ab66217), rabbit anti-ABCG1 (Abcam, ab52617), mouse anti-Caveolin-1 (Abcam, ab17052), rabbit anti-Apolipoprotein E (Abcam, ab52607), mouse anti-LDLR (Millipore, MABS26), rabbit anti-ACAT1 (Abcam, ab168342), rabbit anti-CYP46A1 (Sigma–Aldrich, SAB2100523), mouse anti-KDEL (Santa Cruz, sc-58774), rabbit anti-flotillin (Abcam, ab41927), rabbit anti-SR-B1 (Abcam, 52629), mouse anti- N Cadherin (Abcam, ab98952), mouse anti-Aβ (Abcam, ab126649), and rabbit anti-LRP1 (Abcam, ab92544). Goat anti-mouse (#14709) and rabbit (#7074) biotinylated secondary antibodies were from Cell Signaling Technology. Antibodies for immunofluorescence included anti-CYP46A1 (Abcam, ab82814), goat anti-mouse (Abcam, ab150120), and goat anti-rabbit (Abcam, ab96899).

Subcellular fractionation and protein analysis

Check if the same lab product or an alternative is used in the 5 most similar protocols
Subcellular fractionation and Western blot analysis were performed at postnatal age p21 as described in Gardoni et al. (2006; 2001) . After the Triton-soluble fraction (TSF) and Tritoninsoluble fraction (TIF) were prepared, the latter was thoroughly tested for the absence of the presynaptic marker synaptophysin and for the presence of post-synaptic marker PSD95.
Membrane-associated Cyp46 (Pasciuto et al., 2015) and transferrin receptor, respectively, were used as normalisers. The following specific antibodies were used for Western blotting:
synaptophysin (abcam ab8049), cyp46 (ab82814), Fmrp (Ram II), transferrin R (Abcam ab84036), GABA A α2 (Abcam ab72445), GABA A ß1 (Abcam ab16703), GABA A δ (Millipore Ab9752), PSD95 (Thermo Scientific 6G6-1C9).

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.
