No. The volumes provided in the table are for a single gel. Transfer Buffer Formulations The following buffers are recommended for use with all of Bio-Rad’s electrophoretic transfer cells. Konto erstellen, View recommended buffer formulations under Buffer Recipes tab. No. No. LDS Sample Buffer: 106 mM Tris HCl, 141 mM Tris Base, 2% LDS, 10% Glycerol, 0.51 mM EDTA, 0.22 mM SERVA Blue G250, 0.175 mM Phenol Red, pH 8.5. NuPAGE Transfer Buffer, Cat. Prepare 400 ml NuPAGE transfer buffer (using 20x transfer buffer stock - kept at 4 deg) final concentrations in transfer buffer: 1.25X Transfer Buffer 5% Methanol Final volume 400 ml Note: depending on the protein properties, can use up to 15% Methanol. No. 8 Description of the NuPAGEfi Electrophoresis System, Continued NuPAGEfi Bis-Tris Discontinuous Buffer System The NuPAGEfi Bis-Tris discontinuous buffer system involves three ions: • Chloride (-) is supplied by the gel buffer and serves as a leading ion due to its high affinity to the anode as compared to other anions in the system. The volumes provided in the table are for a single gel. LC2676), Invitrogen NuPAGE LDS Sample Buffer (4X) (Cat. Tris-Glycine Native Running Buffer: 25 mM Tris Base, 192 mM Glycine, pH 8.3. No. No. Scale volumes proportionally based on the number of gels to be cast. 6 The following recipes are for approximately 25 mL of separating gel, enough for four 1.0-mm thick mini gels. 21095), Restore Fluorescent Western Blot Stripping Buffer, 100 mL (Cat. 28348), Thermo Scientific RIPA Lysis and Extraction Buffer, 100 mL (Cat. From a 2 mg/mL antibody stock, dilute 1:5,000 to 1:20,000: 1:5,000: 3 µL of secondary antibody in 15 mL wash buffer, 1:10,000: 1.5 µL of secondary antibody in 15 mL wash buffer, 1:20,000: 0.75 µL of secondary antibody in 15 mL wash buffer. LC3675); Wash buffer (Tris-buffered or phosphate-buffered saline with 0.05% Tween 20, Cat. After protein transfer, wash the membrane in deionized water 4 times for 5 minutes each with agitation to remove all transfer buffer. Place each blot in a sheet protector or on a clean surface prior to imaging to prevent contamination. MOPS SDS Running Buffer: 50 mM MOPS, 50 mM Tris Base, 0.1% SDS, 1 mM EDTA, pH 7.7. No. 28358), Pierce 20X PBS Buffer, 500 mL (Cat. It maintains the neutral pH environment established during electrophoresis. Prepare the following stock solutions: all solutions can be stored at room temperature. Remove the blot from working solution and drain excess reagent. No. A western blot experiment, or western blotting, is a routine technique for protein analysis. Directions for 1X Transfer Buffer: 1) Dissolve Tris base and glycine together in 1.6 L of ddH 2 O. 2) Add methanol and mix. Ensure the volume of the antibody solution is enough to fully cover the membrane and protect the membrane from bright light to prevent photobleaching of the fluorescent dyes. 10x Transfer buffer: For 4 L • 121.1 g Tris base • 576 g glycine • Bring up the volume to 4 L with ddH 2O 1x Transfer buffer: For 1 L • 700 mL cold ddH 2O • 100 mL 10x Transfer buffer • 200 mL methanol 20x TBS: For 4 L • 193.6 g Tris base • 640 g NaCl • Bring up the volume to 3.2 L with ddH 2O Remove gel from glass or plastic plates, cut off stacking gel. Nitrocellulose: equilibrate directly in transfer buffer for 5 minutes. *NuPAGE® Transfer Buffer with 10% methanol provides optimal transfer of a single gel in the blot module.
