Invitrogen Novex Tris-Glycine Mini Gels, WedgeWell format, are polyacrylamide gels that provide reproducible separation of a wide range of proteins into well-resolved bands with two times the loading capacity. Novex Tris-Glycine Mini Gels are based on traditional Laemmli protein electrophoresis that allow the use of Laemmli sample and running buffers.

Features of Novex Tris-Glycine gels, WedgeWell format, include:
• Improved shelf life—store gels for up to 7 months at 4°C
• Diversity—use for native and denaturing protein assays
• Wedge-shaped wells—easily load up to two times more sample volume
• Fast run conditions—quickly separate your proteins using constant voltage in less than 60 minutes

Choose the right gel format for your experiments
Novex Tris-Glycine gels, WedgeWell format, come in a variety of fixed concentrations from 6% to 18%, as well as gradients with ranges of 4–12%, 4–20%, 8–16%, and 10–20%. You can select from our many well formats, including 10-, 12-, and 15-well, and different pack sizes.

Run your proteins in native or denatured form
Novex Tris-Glycine gels, WedgeWell format, do not contain SDS and can be used to run your proteins in native or in denatured form. For denatured proteins, we recommend using Novex Tris-Glycine SDS Sample Buffer (LC2676) and Novex Tris-Glycine SDS Running Buffer (LC26755). For native proteins, we recommend using Novex Tris-Glycine Native Sample Buffer (LC2673) and Novex Tris-Glycine Native Running Buffer (LC2672).

Convenient to use
Novex Tris-Glycine gels, WedgeWell format, have innovative wedge-shaped wells that allow up to two times more sample load volume than other 1.0 mm-thick gels. The wedge-shaped wells also have larger openings, making sample loading easier.

For transferring your proteins to a membrane, we recommend using Novex Tris-Glycine Transfer Buffer (LC3675) when preforming traditional wet transfer using the Invitrogen Mini Blot Module (B1000). Transfers can also be performed with rapid semi-dry transfer using the Invitrogen Power Blotter or rapid dry transfer using theiBlot 2 Gel Transfer Device (IB21001).

Frequently asked questions (FAQs)

I would like to know if the product Novex WedgeWell 14%, Tris-Glycine, 1.0 mm, Mini Protein Gels (Cat. No. XP00140BOX) are compatible with the Bio-Rad mini-PROTEAN Tetra cell for western blot and SDS-PAGE.

The Novex WedgeWell 14%, Tris‐Glycine Mini Protein Gels have a cassette dimension of 10 cm X 10 cm. These gels are meant to be run in the XCell SureLock Mini‐Cell (Cat. No. EI0001: https://www.thermofisher.com/order/catalog/product/EI0001?SID=srch-srp-EI0001) and cannot be run in the Bio‐Rad mini‐PROTEAN Tetra cell for western blot and SDS-PAGE.

I am transferring a Tris-Glycine gel using constant voltage and the current reading is way over the expected starting current. Can you offer some suggestions?

The most common cause of abnormally high current is the transfer buffer. If the transfer buffer is too concentrated, this leads to increased conductivity and current. High current may also occur if Tris-HCl is accidentally substituted for the Tris base required in the transfer buffer. This will again result in low buffer pH and lead to increased conductivity and current and subsequently, overheating. We recommend checking the transfer buffer and its reagent components and re-diluting or remaking the buffer.

What are the main advantages of NuPAGE gels over Invitrogen Tris-Glycine gels?

NuPAGE gels have the following advantages over Tris-Glycine gels:

*Higher stability and longer shelf life: NuPAGE Bis-Tris gels and NuPAGE Tris-Acetate gels have a lower operating pH (pH 7 for NuPAGE Bis-Tris gels and pH 8.1 for NuPAGE Tris-Acetate gels) than Invitrogen Tris-Glycine gels (pH 9.5). At basic pH, polyacrylamide hydrolyzes to polyacrylic acid and ammonia whereas at neutral pH, this hydrolysis is slower. Hence, NuPAGE gels have higher stability and longer shelf life than Invitrogen Tris-Glycine gels (12 months at 4-25 degrees C for NuPAGE Bis-Tris gels and 8 months at 4 degrees C for NuPAGE Tris-Acetate gels vs 4-8 weeks at 4 degrees C for Tris-Glycine gels).

*Better resolution of proteins due to:

- Reduced undesired chemical modifications: Free acrylamide alkylates proteins at basic pH (8.5 to 9.0). It targets sulfhydryl cysteines and amine groups at the N-terminus and on lysines. This modification does not happen at pH below 8. Hence, proteins run on NuPAGE gels undergo fewer of these undesired chemical modifications than those run on Tris-Glycine gels.

- Reduced hydrolysis of proteins: Heating of Tris-Glycine sample buffer (pH 6.8) results in a drop in pH, causing Asp-Pro cleavage of proteins. High temperature and longer duration of heating/boiling increase the rate of this cleavage resulting in multiple peptide bands of decreased intensity. At 100 degrees C, the pH drops as low as pH 4.3. On the other hand, NuPAGE LDS sample buffer (pH 8.5) drops to pH 8.1 when heated to 70 degrees C, avoiding this cleavage.

*Faster run times: 35-50 min for NuPAGE Bis-Tris gels and 1 hour for NuPAGE Tris-Acetate gels vs 90 min for Tris-Glycine gels

How does the operating pH for Tris-Glycine gels differ from that for NuPAGE Bis Tris and NuPAGE Tris-Acetate gels?

The operating pH for Tris-Glycine gels is 9.5; the operating pH for NuPAGE Bis-Tris gels is 7 and for NuPAGE Tris-Acetate gels is 8.1.

Can I run Mini gels with 10 cm gel cassettes using a Bolt Mini Gel Tank?

To run Mini gels with 10 cm gel cassettes using a Bolt Mini Gel Tank (without replacement of 10.5 cm cassette clamp cam handles with 10 cm cassette clamp cam handles), please use the instructions provided on Page 22 of the manual (https://tools.thermofisher.com/content/sfs/manuals/mini_gel_tank_man.pdf).

Note: For optimal results, to run 10 cm cassette Mini gels with a Bolt Mini Gel Tank, one should replace the black 10.5 cm cassette clamp cam handles on the Bolt Mini Gel Tank with gray 10 cm cassette clamp cam handles (Cat. No. A26732). Instructions for replacement of the cam handles can be found on Page 20 of the manual (http://www.thermofisher.com/us/en/home/life-science/protein-biology/protein-gel-electrophoresis/protein-gel-electrophoresis-chamber-systems/mini-gel-tank/resources-upgrading-bolt-mini-gel-tank.html) or in this video (https://www.youtube.com/watch?v=1FtiX8Skllw).
