Features of NuPAGE Tris-Acetate gels:
• High resolution—gels offer optimal separation of high molecular weight proteins
• Better protein integrity—sample preparation process has been optimized to help preserve proteins
• Longer self life—gels can be stored for at least eight months

Choose the right NuPAGE Tris-Acetate gel for your protein separation
Obtain optimal separation of your high molecular weight proteins by choosing the right combination of gel and running buffer. NuPAGE Tris-Acetate protein gels come in a polyacrylamide concentration of 7% and a 3–8% gradient. Gels come in two sizes: mini (8 cm x 8 cm) or midi (8.7 cm x 13.3 cm) and either 1.0 mm (mini and midi gels) or 1.5 mm (mini gel format only) in thickness. NuPAGE Tris-Acetate gels also come in multiple well formats. Mini gels can be run using our XCell SureLock Mini-Cell (EI0001) or Mini Gel Tank (A25977). Midi gels can be run using our XCell4 SureLock Midi-Cell (WR0100) or conveniently with the Bio-Rad Criterion™ Cell using our adapters (WA0999).

Run your proteins in native or denatured form
NuPAGE Tris-Acetate protein gels do not contain SDS and can be used to separate proteins in native or denatured form. For denatured proteins, we recommend using NuPAGE LDS Sample Buffer (NP0007) and NuPAGE Tris-Acetate SDS Running Buffer (LA0041). For native proteins, we recommend using Novex Tris-Glycine Native Sample Buffer (LC2673) and Novex Tris-Glycine Native Running Buffer (LC2672).

For transfer of proteins to a membrane, we recommend using NuPAGE Transfer Buffer (NP00061) for traditional wet transfer using the XCell II Blot Module (EI9051) or the Mini Blot Module (B1000). Alternatively, rapid semi-dry transfer can be done using the Invitrogen Power Blotter or rapid dry transfer using the iBlot 2 Gel Transfer Device (IB21001).
