NuPAGE™ Tris-Acetate Midi Protein Gels, 3 to 8%, 1.0 mm

Invitrogen NuPAGE Tris-Acetat-Protein-Gele bieten eine hervorragende Trennung von Proteinen mit hoher Molekülmasse. Es sind leistungsstarke Polyacrylamid-Gele, die die Denaturierung oder die nativen Bedingungen des traditionellen Laemmli-Systems simulieren. Die einzigartige Pufferformulierung sorgt während der Elektrophorese für einen niedrigen pH-Wert, was im Vergleich zu herkömmlichen Tris-Glycin SDS-PAGE-Gelen zu einer besseren Auflösung von Proteinen mit höherer Molekülmasse führt.

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

Features of NuPAGE Tris-Acetate gels include:

• High resolution—gels offer optimal separation of high molecular weight proteins
• Better protein integrity—sample preparation process 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 x 8 cm) or midi (8.7 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 (Cat. No. EI0001) or Mini Gel Tank (A25977). Midi gels can be run using our XCell4 SureLock Midi-Cell (WR0100) or 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 (LC26720).

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 Power Blotter or rapid dry transfer using the iBlot 3 Gel Transfer Device (IB31001).
