BupH™ Tris-Glycine Buffer Packs (Thermo Scientific™)

Thermo Scientific BupH Tris-Glycine Transfer Buffer Packs are pouches of dry-blend powder that are each sufficient to make 500 mL of standard transfer buffer for wet or semi-dry electrophoretic protein transfer from gel to blotting membrane.

Features of Thermo Scientific BupH Tris-Glycine Transfer Buffer Packs:

Tris-glycine buffer—dissolved in 400 mL of water and 100 mL methanol, makes 25 mM Tris, 192 mM glycine, pH 8
Convenient—dissolve contents of one envelope in water and the buffer is ready to use
Save time and trouble—no weighing, no pH adjustment, no need to stock individual components, and no need to make and store large volumes of stock solution in advance of daily needs
Long shelf life—stocking and storage as dry packs eliminates concerns about long-term stability of stock solutions
Eliminate variables—our quality control ensures that every pack will yield the same, consistent buffer

Applications:
• Running buffer for gel-to-membrane electrophoretic transfer

BupH Dry-Blend Packs of Tris-glycine buffer are easy to use. Simply empty contents of one foil envelope pack into a beaker, add ultrapure water and stir to dissolve. The packs eliminate weighing time and tedious pH adjustments. When dissolved in 400 mL of water and 100 mL methanol, makes 25 mM Tris, 192 mM glycine, pH 8.

NativePAGE™ 5% G-250 Sample Additive (Invitrogen™)

NativePAGE™ 5% G-250 Sample Additive is added to samples prepared with the NativePAGE™ Sample Buffer and detergents (10% DMM or 5% Digitonin) just prior to applying the samples to NativePAGE™ gels. This Additive is also included in the NativePAGE™ Sample Prep Kit. The samples prepared with 10% DDM, 5% Digitonin, or the NativePAGE™ Sample Prep Kit are compatible with NativePAGE™ Novex Bis-Tris Gels for native electrophoresis showing increased resolution and reduced streaking.

Pierce™ Lane Marker Reducing Sample Buffer (Thermo Scientific™)

Thermo Scientific Pierce Lane Marker Reducing Sample Buffer is a ready-to-use 5X SDS-PAGE sample loading buffer in a reducing formulation, with a pink dye buffer-front marker. This Sample Buffer contains DTT as the reducing agent, eliminating the strong odor associated with mercaptoethanol-containing buffers.

Features of Lane Marker Sample Buffer:

Easy to see—bright pink dye marks the buffer front, clearly indicating the progress of the electrophoresis run
Concentrated—5X stocks enable a greater range of protein sample volumes to be used for electrophoresis
Transferable marker dye—pink dye transfers with protein to nitrocellulose membrane, enabling verification of transfer direction and orientation of the blot

Lane Marker Reducing Sample Buffer is convenient and ready to use for SDS-polyacrylamide gel electrophoresis (SDS-PAGE) and Western blotting. Formulated as a 5X stock rather than the traditional 2X stock, it enables a larger volume of protein solution to be included in the sample that is loaded in each well. Particularly unique in this buffer is the use of a bright pink tracking dye instead of the traditional bromophenol blue dye. This pink dye marks not only the dye front in the gel but also transfers and permanently binds to nitrocellulose membranes. Consequently, the dye can be used to assess transfer efficiency and align cut membranes.

Lane Marker Sample Buffer is easy to use. Simply mix one part Sample Buffer with four parts protein sample, heat denature, and then load the gel sample wells. Visualize progress of the electrophoresis run by monitoring the location of the pink dye front. Lane Marker Sample Buffer may be used in denaturing gels of all kinds and is compatible with coomassie dye and silver staining techniques, as well as Western blotting procedures.

Note: This product is not compatible with fluorescent detection systems. (The pink tracking dye fluoresces strongly.)

Novex™ IEF Cathode Buffer pH 3-10 (10X) (Invitrogen™)

Novex® IEF Cathode Buffer pH 3-10 (10X) is optimized pre-mixed IEF cathod buffer for using with Novex® pH 3-10 IEF gels. IEF is a sensitive technique which is affected by many factors. The optimized pre-mixed IEF buffers reduce variability and ensure consistent results.

Usage note: The IEF cathode buffer solutions contain a reagent that varies from white to light yellow in color. This color variation may produce a similar color variation in the final solution, from colorless to yellowish in tone. This color will not affect product performance.

Novex™ Tris-Glycine SDS Sample Buffer (2X) (Invitrogen™)

Novex Tris-Glycine SDS Sample Buffer (2X) is used to prepare protein samples for denaturing gel electrophoresis using Tris-Glycine gels. It has a pH of 6.8 and contains bromophenol blue as a tracking dye.

See all available buffers and reagents available for SDS-PAGE

To use: Heat the sample in a 1X dilution (reduced or non-reduced) at 85°C for 2–5 minutes for optimal results. Heating samples at 100°C in SDS-containing buffers results in proteolysis.

NativePAGE™ Sample Buffer (4X) (Invitrogen™)

NativePAGE™ Sample Buffer (4X) is a solution used to solubilize native protein samples prior to use with the NativePAGE™ Gel System.
