Protein lysates were prepared in LDS sample buffer and separated using the Bolt SDS-PAGE system on 12% Bis-Tris gels, before transfer to nitrocellulose membranes (all Life Technologies). Protein expression was analyzed using the following antibodies: mouse monoclonal acetyl-Lysine, mouse α-Tubulin, rabbit GAPDH, rabbit Glutamate Dehydrogenase (GDH), rabbit acetyl-Tubulin K40, rabbit HDAC6, rabbit LC3A/B, rabbit COX IV, rabbit Succinate Dehydrogenase A (SDHA), rabbit phospho-ACC from Cell Signaling Technologies; rabbit PINK1 from Novus Biochemicals. Fluorescent anti-mouse or anti-rabbit secondary antibodies (red, 700 nm; green, 800 nm) from LiCor were used to detect expression levels.

Protein levels of pAKT, AKT and PI3K in platelets from COVID‐19 patients and healthy controls were determined by western blot (WB). In brief, following platelet isolation, cells were centrifuged (5 min, 700 g at 4°C) and the platelet pellet resuspended in ice‐cold RIPA lysis buffer (ThermoFisher Scientific) containing Halt™ protease and phosphatase inhibitor cocktail (100×; ThermoFisher Scientific) and EDTA (0.5 M, 100× ThermoFisher Scientific). The proteins were separated by electrophoresis using 12% SDS‐PAGE gels in glycine‐tris buffer and subsequently transferred to polyvinylidene difluoride (PVDF) membranes (0.45 µm; Merck). Finally, the membranes were incubated with rabbit phospho‐AKT antibody (1:1000; Invitrogen), mouse AKT antibody (1:1000; Abcam, Signaling), rabbit pPI3K (p85,N‐SH, 1:1000; Merck) and mouse α‐Tubulin (Cell Signaling) which was followed by the incubation with appropriate secondary anti‐rabbit IRDye®800 and anti‐mouse antibody IRDye®680 (1:3000, LI.COR®). Protein bands were detected with Odyssey infrared imaging system (LI.COR®). Relative intensity of western blots was quantified using ImageJ software (NIH).

Western blotting was performed as previously described (21 (link)). Briefly, cells were lysed in Laemmli's buffer. Total proteins were separated using SDS-PAGE and were then transferred to PVDF membranes (Bio-Rad Laboratories, Inc.). After blocking, the membranes were incubated with primary antibodies against rabbit phosphorylated (p)CREB (Ser133; 1:1,000, cat. no. ab32096; Abcam), rabbit PARP-1 (1:1,000 cat. no. 9542; Cell Signaling Technology, Inc.) and mouse α-tubulin (1:1,000, cat. no. 3873; Cell Signaling Technology, Inc.) which was followed by incubation with appropriate horseradish peroxidase-conjugated secondary antibodies against rabbit (1:2,000, cat. no. p0448; Dako Agilent Technologies) and mouse (1:2,000, cat. no. p0260; Dako Agilent Technologies). The expression was visualized using an ECL detection kit (cat. no. RPN2106; Cytiva). Images were acquired using ImageQuant LAS 4000 Mini biomolecular imager (Cytiva). Semi-quantification on the relative expression of proteins was performed using ImageJ 2.1.0 software (National Institutes of Health).

The cells were washed twice with PBS, and lysed using M-PER mammalian protein extraction reagent (Thermo Fisher Scientific, USA) with protease (Thermo Fisher Scientific, USA) and phosphatase (Nacalai Tesque, Japan) inhibitors. For western blot analysis, proteins were separated by SDS-PAGE and transferred onto PolyVinylidene DiFluoride (PVDF) membranes. The membranes were blocked with 5% non-fat dry milk and incubated overnight at 4 °C using the following primary antibodies: mouse V5 (Nacalai Tesque, USA), rat FLAG (Novus Biologicals, USA), rabbit ERK1/2, rabbit phospho-ERK1/2, mouse α-Tubulin (Cell Signaling Technology, USA), or mouse α smooth muscle actin (SMA) (Sigma-Aldrich, USA). Bands were detected using Chemi-Lumi One Super (Nacalai Tesque, Japan) and Chemiluminescence detection system LAS-4000 Mini (GE Healthcare, USA).

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.
