Pierce™ 1-Step Transfer Buffer (Thermo Scientific™)

Thermo Scientific Pierce 1-Step Transfer Buffer is designed for rapid semi-dry transfer of 10-300kDa proteins from polyacrylamide gels (SDS-PAGE) to nitrocellulose or PVDF membranes using the Pierce G2 Fast Blotter.

Features of 1-Step Transfer Buffer:

Fast—high ionic strength formulation provides 5- to 10-minute protein transfer when used with compatible fast semi-dry blotting systems
Ready to use—supplied as a 1X solution that is stable and ready to use at room temperature
Optimized—designed for seamless and reliable performance with the Pierce G2 Fast Blotter
Compatible—effective with other semi-dry transfer devices equipped with a suitable high-current power supply, including the original Pierce Fast Semi-Dry Blotter (Part No. 88217)
Economical—excellent performance without the special or costly consumables that are required by other fast semi-dry transfer devices

When used with the Pierce G2 Fast Blotter, this buffer provides effective gel-to-membrane transfer of proteins in 5 to 10 minutes with efficiency that is equal to, or better than, conventional Western blotting techniques. Pierce 1-Step Transfer Buffer is also compatible with other protein semi-dry transfer devices, including the original Pierce Fast Semi-Dry Blotter (Part No. 88217), when they are paired with a suitable high-current power supply. Such devices 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.

Requires:
Pierce G2 Fast Blotter (Part No. 62288) or other semi-dry transfer device that is equipped or paired with a capable high-current power supply.

Fast blotting methods require a high-current power supply, such as the Pierce G2 Fast Blotter, and an optimized high ionic strength transfer buffer, such as Pierce 1-Step Transfer Buffer. By increasing the current, excellent transfer efficiency can be achieved in much shorter time compared to conventional methods. Amperage is held at a constant rate based on the surface area of the transfer stack(s) (~22-23mA/cm2) and voltage is limited to 25V.

Pierce™ 10X Western Blot Transfer Buffer, Methanol-free (Thermo Scientific™)

Thermo Scientific Pierce 10X Western Blot Transfer Buffer, Methanol-free is a space-saving stock solution for preparing the methanol-free transfer buffer used with cooled, tank (wet) western blotting transfer apparatus.

Features of 10X Western Blot Transfer Buffer, Methanol-free:

Transfer Buffer—diluted 10-fold in water, the solution is ready to use for electrophoresis (i.e., wet tank transfer from mini gels)
Easy to use—no packets to open, no powder to dissolve, and no methanol required
Increased accuracy—eliminates the possibility of powder remaining in a packet
Saves time—10X concentration eliminates time spent waiting for powder to dissolve
Saves space—storage as concentrated stock minimizes bench space needed for solutions

Pierce Concentrated Buffers are ready to use without having to weigh and dissolve dry ingredients or to adjust the pH with concentrated acid or base. Simply dilute the stock solution with pure water and proceed with your experiment. The 10X Western Blot Transfer Buffer is ready to use upon dilution to 1X with water; it does not contain methanol and the addition of methanol is not necessary for use in electrophoresis.

Applications:
• Wet (tank) western blot transfer of proteins to a membrane

NuPAGE™ MOPS SDS Running Buffer (20X) (Invitrogen™)

NuPAGE MOPS SDS Running Buffer (20X) is formulated for running proteins on NuPAGE Bis-Tris gels. It is recommended for separating medium- to large-sized proteins.

Use the right buffer to optimize protein separations
NuPAGE MES SDS Running Buffer and NuPAGE MOPS SDS Running Buffer can both be used with NuPAGE Bis-Tris gels. MES has a lower pKa than MOPS, making the MES SDS Running Buffer faster than MOPS SDS running buffers. The difference in ion migration affects stacking and results in a difference in protein separation range between these buffers. Use of MOPS buffer allows proteins to run slower than when using MES buffer.

Novex Tris-Glycine SDS Running Buffer (10X) is formulated for separation of proteins in their denatured state on Tris-Glycine gels. Tris-Glycine gels provide reproducible separation of a wide range of proteins into well-resolved bands.

Separate native or denatured proteins
Novex Tris-Glycine gels do not contain SDS and can be used to accurately separate both native and denatured proteins, depending upon the sample and running buffers used. To separate denatured proteins on Novex Tris-Glycine gels, use Novex Tris-Glycine SDS Sample Buffer and Novex Tris-Glycine SDS Running Buffer. To separate native proteins use Novex Tris-Glycine Native Sample Buffer and Novex Tris-Glycine Native Running Buffer.
