Flp-In TREx293 Gpr176-GFP (tet-on) cells and the related cells that express an N-terminal N-glycosylation mutant Gpr176-GFP were plated on polylysine-coated coverslips in culture medium containing 1 µg/ml Dox for 15 h. The cells were fixed with 4% paraformaldehyde and mounted in ProLong Gold antifade reagent with DAPI (Thermo Fisher Scientific). The Gpr176 GFP fusion protein subcellular localization was monitored using direct fluorescence from the GFP moiety. For ER staining, cells were treated with 1 μM ER-Tracker Red (Thermo Fisher Scientific). ER-Tracker is a fluorescence-labeled glibenclamide that is capable of visualizing ER via specific binding to the sulphonylurea receptors of ATP-sensitive K+ channels, which are prominent on ER40 (link). For calnexin immunocytochemistry, cells were fixed, permeabilized, and blocked with 5% bovine serum albumin in PBS containing 0.1% Triton X-100, as described41 (link). The cells were immunolabeled with anti-calnexin (BD Transduction Laboratories, #610523) and visualized with Alexa594-conjugated anti-mouse IgG (Thermo Fisher Scientific). Images were captured using an Olympus FV10I-DOC confocal microscope.

Fluorescence imaging was performed using an Olympus FV1000-D (IX81) confocal laser scanning microscope (Olympus, Tokyo, Japan). Images were acquired using FV-10 ASW software (Olympus).
To observe stress granule markers, Ras GTPase-activating protein SH3-domain-binding protein (G3BP1) and T-cell intracellular antigen 1 related protein (TIAR), cells were fixed and then permeabilized in phosphate-buffered saline containing 0.1% Triton X-100 and 1% bovine serum albumin. Coverslips were incubated with an anti-G3BP1 (Cat. #: 611126, BD Biosciences, Franklin Lakes, NJ, USA) or anti-TIAR (Cat. #: 610352, BD Biosciences) mouse monoclonal antibody for 1 h and then incubated with Alexa 594-conjugated anti-mouse IgG (Molecular Probe) for 1 h.

Spheroids were fixed with cold 4% PFA in PBS. After blocking with Block Ace (DS Pharma Biomedical), the spheroids were permeabilized with 0.1% saponin and stained with FITC-conjugated anti-CD44 mAb (clone; IM7, BioLegend) plus biotin-conjugated hyaluronan-binding protein (HABP) (Seikagaku Corp.) After a PBS wash, the spheroids were stained with Alexa594-conjugated streptavidin and 4′, 6-diamidino-2-phenylindole (DAPI). For the analyses of Ki-67 expression, anti-Ki-67 mAb (Becton Dickinson) and Alexa594-conjugated anti-mouse IgG (Molecular Probes) were used. In some experiments, spheroids were treated with hyaluronidase (100 U/ml; Sigma) and incubated with FITC-labeled HA (FL-HA; Seikagaku Corp.) in the presence or absence of anti-CD44 mAb (clone; BRIC 235). Fluorescent images were taken with the BZ-7000 microscope (Keyence). The specificity of the HABP was confirmed by hyaluronidase treatment before HABP staining.

Check if the same lab product or an alternative is used in the 5 most similar protocols
In vitro myelination assays were performed as described previously15 (link). In some experiments, myelination was induced with mGluRs antagonist at concentrations mentioned above. For analysis of myelin profiles by immunocytochemistry, 10 days after initiation of myelination, the culture was fixed with 4% paraformaldehyde/PBS for 5 min. Myelination profiles were visualized by immunocytochemical detection of myelin basic protein (MBP) using anti-MBP antibody (Covance) followed by Alexa-594-conjugated anti-mouse IgG (Invitrogen). For quantification, myelination profiles in 5 randomly chosen fields using a 20x objective lens were counted and the number of myelinated nerve fibers per arbitrary unit area was calculated. Statistical analysis was performed by Student’s t test. All data are reported as mean ± SD; p value of less than 0.05 is considered significant.

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.
