Do not adjust the pH. Search Transfer buffer for western blotting. We offer premixed western blot transfer buffers that are optimized for each gel chemistry. For Research Use Only. Dissolve the following reagents in 100 mL ultrapure water. ** Directions for 1X Transfer Buffer: 1) Dissolve Tris base and glycine together in 1.6 L of ddH 2 O. Tris-Glycine and Tricine Systems Do not adjust the pH of transfer buffers unless specifically indicated. Do not use acid or base to adjust the pH. 25 mM Tris-HCl (pH 7.6) 192 mM glycine 20% methanol 0.03% sodium dodecyl sulfate (SDS) Buffer is stable for 6 months at room temperature. Bis-Tris transfer buffer with 10% methanol and antioxidant for reduced samples. Before western transfer, dilute to 1X with water. Use the tabs below to see the recommended transfer buffers and transfer conditions for the gel chemistry being used for western blot wet or semi-dry transfer. Mix well and adjust volume to 125 mL with ultrapure water. The following transfer buffer recipes are provided to allow preparation of buffers from scratch. 25 V constant: Start: 100 mA: 1-2 hr * Current readings represent values when running a single gel, and can vary depending upon the power supply being used. Dissolve the following reagents in 400 mL ultrapure water. ** NOTE: for the proper transfer of large proteins, up to 0.5% SDS may need to be added to 1X Transfer Buffer. ** Current readings represent values when running a single gel, and can vary depending upon the power supply being used. Premixed transfer buffers are a convenient way to ensure high-quality, consistent gel transfer. Sometimes SDS is added to this buffer, generally in the range of 0.1 to 0.25%. Not for use in diagnostic procedures. Such devices should provide constant high current (1.3 to 5.0 amps) to rapidly transfer proteins via the high ionic strength conditions supplied by the transfer buffer. * Transfer buffer with 10% methanol provides optimal transfer for a single gel in the blot module. 1-Step Transfer buffer is a high ionic strength formulation which allows for 5-minute to 12-minute protein transfer when used with compatible semi-dry blotting systems. 3) Add ddH 2 O to a final volume of 2 L. The standard transfer buffer for western blots, called Towbin buffer, is 25 mM Tris, 192 mM glycine, pH 8.3 — usually with 20% methanol (vol/vol). Thermo Fisher Scientific. If you are transferring 2 gels, increase the methanol content to 20% to ensure efficient transfer. Adjusting the pH of transfer buffers can result in increased buffer conductivity, manifested by higher initial current output and decreased resistance. Find the suggested transfer buffer recipes for wet transfer below. Tris Glycine Transfer Buffer with 20% methanol. Mix well and adjust volume to 500 mL with ultrapure water. * Current readings represent values when running a single gel, and can vary depending upon the power supply being used. Don't have an account ? 2) Add methanol and mix. Buffer is stable for 6 months when stored at 4°C. Protein Electrophoresis and Western Blotting Education Center, Download: Western Blotting Overview Brochure, Download: HMW Protein Transfer Application Note. The pH listed for each buffer is for the 1X solution. 1X Transfer Buffer should be pH 8.3 before addition of SDS or methanol. 1-Step Transfer Buffer is compatible with Power Blotter and other protein semi-dry transfer devices, when they are paired with a suitable high-current power supply.
