About NuPAGE Tris-Acetate gels
NuPAGE Tris-Acetate protein gels provide excellent separation of large molecular weight proteins. NuPAGE Tris-Acetate gels are high performance polyacrylamide gels that simulate the denaturing or the native conditions of the traditional laemmli system. The unique buffer formulation maintains a low operating pH during electrophoresis, resulting in superior resolution of proteins compared to traditional Tris-glycine SDS-PAGE gels.

For transferring your proteins to a membrane, we recommend using for NuPAGE Transfer buffer for traditional wet transfer using the Mini Blot Module. Alternatively, rapid semi-dry transfer can be done using the Invitrogen Power Blotter or rapid dry transfer using the iBlot 2 Gel Transfer Device.

Bolt™ 10% Bis-Tris Plus Gels, 10-well (Invitrogen™)

Invitrogen Bolt Bis-Tris Plus gels are precast polyacrylamide gels designed for optimal separation of a wide range of protein sizes under denaturing conditions. Similar to NuPAGE Bis-Tris gels, Bolt Bis-Tris Plus gels are designed to deliver consistent gel performance and provide a neutral pH environment that minimizes protein modifications with increased loading capacity. Bolt gels are ideal for western blot transfer and analysis, and any other techniques where protein integrity is crucial. Use Bolt Bis-Tris Plus gels to obtain optimal results for your day-to-day protein separation needs. Bolt Bis-Tris Plus gels come in four gel types and multiple well formats. Each box contains 10 gels. A Mini Gel Tank is required for use of all Bolt gels.

Novex™ 10-20% Tricine Protein Gels, 1.0 mm, 12-well (Invitrogen™)

Invitrogen Novex Tricine Gels provide separation of low molecular weight proteins and peptides. The Tricine system is a modification of the tris-glycine discontinuous buffer system developed by Schaegger and von Jagow (Schaegger and von Jagow, 1987) specifically for resolving peptides and low molecular weight proteins. In this system the tricine replaces the glycine in the running buffer, resulting in more efficient stacking and destacking for low molecular weight proteins and higher resolution of smaller peptides.

Features of Novex Tricine protein gels:
• Increased resolution of proteins with molecular weights as low as 2 kDa
• Improved compatibility with direct sequencing of proteins after transferring to PVDF
• Minimized protein modification due to the lower pH of the tricine buffering system
