LU-NB-1, LU-NB-2, and LU-NB-3 PDX-derived tumor organoids were dissociated into single cells and seeded into opaque 96-well plates (Corning Inc., Corning, NY), 5000 cells per well, and treated immediately with a range (0–100 nM) of rigosertib concentrations. Cells were incubated for 72 h. Cell viability was calculated as a percentage of control wells based on CellTiter-Glo (G7571; Promega, Madison, WI) luminescence. Luminescence was measured with a Synergy2 Multi-Mode plate reader (BioTek, Winooski, VT). Biological triplicates were used.

Geopolymer Pots for Wheat Growth

Check if the same lab product or an alternative is used in the 5 most similar protocols
Seeds of spring wheat, var. Almari, were germinated and grown for ten days in pots filled with small pieces of cellulose pats. The plant’s morphology was compared for plants grown in geopolymer pots vs plastic pots. Ion adsorption and desorption properties of the geopolymer foam pots were tested. The pots were immersed for 24 h in the mineral solution described above. Ten subsequent rinses with distilled water were performed. At each step, pots were filled with 50 mL distilled water and after 24 h, the leaches were analysed spectrophotometrically (Synergy 2 Multi-Mode Plate Reader, BioTek Instruments, Winooski, VT, USA). The procedures were carried out in accordance with the manufacturer’s instructions using commercial kits ZW 535550 (Slandi Ltd. Warsaw, Poland), 1-403-B125, 1-440-0080 (BioMaxima S.A., Lublin, Poland) for nitrogen, phosphorus, and potassium analysis, respectively, and standards for their content quantification (Química Clínica Aplicada S.A.).

LC and DR tissue punches were homogenized in 200 μL of tissue lysis buffer (500 mM NaCl, 50 mM Tris HCl pH 7.6, 10% NP-40, 70% glycerol) with 0.02% protease phosphatase inhibitor cocktail (Thermo Scientific, Waltham, MA) in conjunction with mechanical disruption with a bullet blender (Next Advance, Averill Park, NY) at 4°C. Protein concentrations of the supernatant were assessed using a BCA assay (Thermo Scientific, Waltham, MA) according to the manufacturer’s protocol and read using a Synergy 2 Multi-Mode plate reader (Bio Tek, Winooski, VT) with Gen5 software (Bio Tek, Winooski, VT). The remaining tissue homogenate was stored at −80°C.

Each dsDNA containing 5’ Alexa-488 fluorescent dye was synthesized, annealed, and purified by IDT. Each 40 µl reaction contained 5 nM fluorescent DNA and PRC2 in binding buffer (50 mM Tris-HCl pH 7.5, 25 mM KCl, 2.5 mM MgCl2, 0.1 mM ZnCl2, 2 mM 2-mercaptoethanol, 0.1 mg/ml bovine serum albumin, 5% v/v glycerol). Reaction was incubated for 30 min at 30°C, followed by measuring fluorescence polarization in a 384-well plate with Synergy 2 multi-mode plate reader (BioTek). For competitor assays, initial signals were measured (defined as t = 0) before adding competitors. RNA or dsDNA cold competitors were added into the reactions and the measurements were taken every 20 s for 4 h.

Cell cultures were lysed with RIPA buffer (ThermoFisher), and cellular and extracellular material was collected using cell scrapers (Biologix), sonicated, and centrifuged to separate soluble and insoluble material. Pelleted material was then subjected to two 1 hour hot 0.25 M oxalic acid treatments at 100°C to extract digested α-elastin soluble derivatives. Samples were then analyzed via the Fastin assay (Biocolor), following the manufacturer’s instructions, with absorbances measured at 513 nm using a Synergy 2 multi-mode plate reader (BioTek).

5×106 cells were electroporated with 10 μg HCV genomic RNA as described previously (56 (link)) and plated to 25 cm2 cell culture vessels for assays to assess intracellular viral RNA abundance (GLuc assay) or extracellular infectious virus production (FFU assay). For GLuc assays, cell culture medium was harvested and replaced at 6, 24, 48 and 72 hours after electroporation. Cell culture medium was analyzed for GLuc activity using the BioLux Gaussia substrate (New England BioLabs) on a Synergy 2 Multimode Plate Reader (Biotek). For FFU assay, cell culture medium was harvested and replaced at 24, 48 and 72 hours after electroporation. Infectious virus was measured as described previously (56 (link)).

Check if the same lab product or an alternative is used in the 5 most similar protocols
Reduced glutathione (GSH), oxidized glutathione (GSSG), and total glutathione levels were determined in THP-1 cells following treatment. Glutathione was determined based on modifications of the Tietze recycling assay [22] (link). In brief, cells were lysed in lysis buffer containing 0.1% Triton X-100 in PBS buffer, pH 7.4, containing 10 µM DTPA. Cell lysates were treated with triethanolamine (TEA), 2-methyl-5-vinylpyridine (MVP), and 5% 5-sulfosalicylic acid (5-SA) to measure GSSG or 5-SA alone to measure GSH based on adapted methods from Anderson and Neufer [23] (link), [24] (link). Glutathione was determined based on the reduction of DTNB (Ellman's Reagent) at 412 nm in the Diabetes Research Center BioAnalytical Redox Biology Core (DK 079626) using a Synergy-2 Multimode plate reader (Biotek, Winooski, VT). Samples were normalized to cellular protein.

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.
