Check if the same lab product or an alternative is used in the 5 most similar protocols
A7r5 rat aortic smooth muscle cells (RAoSM) (ATCC, Rockville, MD, United States) were cultured in 48-well clusters in DMEM growth media (GibcoTM), supplemented with 10% Fetal Bovine Serum (GibcoTM) and 1% Penicillin/Streptomycin (Biosera).
At confluence, cells were serum-starved for 2 h in media containing 0.1% BSA and were then pre-exposed for 5 min to the non-selective phosphodiesterase (PDE) inhibitor isobutyl-methyl-xanthine (IBMX, 1 mM). Then, they were treated with the sGC stimulator BAY 41-2272 at 10 μΜ or a combination of the heme-dependent NO donor sodium nitroprusside (SNP at 100 μΜ) and BAY 41-2272, for 15 min. Some of the cells that received the BAY compound or the BAY/SNP combination were also treated with the heme-oxidizing compound 1H-[1,2,4]oxadiazolo[4,3-a]quinoxalin-1-one (ODQ) (at 10 μΜ) or its vehicle control (DMSO), either 20 min before the addition of IBMX (and hence before the sGC agonists) or 2 min after the addition of the agonist(s).
Cellular cGMP content was assessed as previously described (Argyriou et al., 2021 (link)), by collecting the extracts with HCl 0.1 M, which were analyzed by a commercial ELISA kit according to the manufacturer’s instructions. The cGMP levels in each well were normalized for the respective total protein determined by a Micro BCA Protein assay kit.

Mouse 3T3-L1 preadipocytes (CL-173, ATCC, Manassas, United States) and C2C12 myoblast cell line (CRL-1772, ATCC, Manassas, United States) were cultured in DMEM growth media (Gibco, Thermo Fisher Scientific, Waltham, United States) supplemented with 10% heat-inactivated bovine calf serum (Sigma-Aldrich, Darmstadt, Germany), 1% antibiotics (Gibco), and 1% L-glutamine (Gibco). After reaching confluency, cells were seeded in a 24-well plate at a seeding density of 42, 0000/well. After 24 h, the medium was changed to DMEM growth media without serum for 24 h. Following cell’s starvation, cells were washed once with phosphate buffered saline (PBS) to remove any remnants of FCS and then treated with a conditioned media containing 10% human serum of one of the different athlete serum groups (LE/LP, HE, and HP) or the non-athlete human serum (n = 3 per group) as a negative control. Conventional fetal bovine serum (FBS)-containing media was also used as a control for cell culture. After 72 h incubation, media supernatants were collected from all wells for measurement of cytokines, and the cells were lysed using RIPA buffer (Thermo Fisher Scientific) to measure insulin signaling proteins’ phosphorylation.

Check if the same lab product or an alternative is used in the 5 most similar protocols
As the p10 protein of Ro-BatCoV GCCDC1 is the first reported in an enveloped virus, we first tried to define the key amino acids for the p10 protein in the Ro-BatCoV GCCDC1 as described previously for p10 protein of reoviruses [24 (link), 25 (link)]. For syncytial indexing of six mutant constructs, each well of BHK-21 monolayer cells in a 6-well plate were transfected with 2 μg of plasmid DNA using Polyethylimine (PEI, Polysciences Inc.) and incubated for 5 h before replacing the transfection mixture with DMEM growth media (Invitrogen) supplemented with 10% fetal bovine serum (GIBCO). Transfected cells were paraformaldehyde-fixed and stained with Wright-Giemsa at the indicated times, and syncytia were observed and pictures were taken at ×100 magnification on an Olympus IX51FL+DP70 microscope.

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.
