RunBlue® Bis-Tris Protein Gels have been developed by Expedeon™ to provide an alternative to NuPAGE® Bis-Tris gels. These protein gels run with the same voltages, in the same tanks, using the same MES/MOPS buffers as NuPAGE gels. RunBlue Bis-Tris gels achieve highly comparable results with exceptional reproducibility and resolution.

Don’t change a thing

Expedeon’s new Bis-Tris gels can be run with standard MES or MOPS buffers depending on the molecular weight range of proteins to be separated and use the same LDS sample buffer and protocols as NuPAGE (200V). The cassettes fit in the NuPAGE SureLock™ tank without any need for adaptors or spacers, and gels are also compatible with the iBlot® dry blotting system. There is no workflow disruption, no downtime, and no transition period.

Don’t compromise on results

Expedeon have over 8 years’ experience in pre-cast gel manufacture and have applied this knowledge to Bis-Tris gel chemistry. A unique manufacturing process with exacting specifications and quality controls results in increased batch to batch consistency between gels. A key element in this process is the use of physically induced gel polymerisation for consistency, as oppose to chemically induced methods which can introduce variability leading to heterogeneous polymerisation. Switching to RunBlue Bis-Tris gels will give better resolution while following the same migration profiles.

Get added benefits

The RunBlue gel range has a number of usability enhancements. A unique composition gives strength with a slight elastic stretch, greatly reducing the risk of tearing or damaging gels. The comb is removed during the manufacturing process to eliminate the risk of damaged or broken gel teeth, and there is no strip to remove from the cassette. Extra wide and deep wells allow loading of samples up to 35 µl in volume for a 12 well gel. A 2 year shelf life at 4°C or 3 months at room temperature provides flexible storage options.

And spend less

Expedeon sell at a significantly lower list price than NuPAGE for both gels and buffers. In addition to Expedeon’s already lower list prices flexible pricing can be discussed with our team. There are no extra costs from changing equipment or reagents because RunBlue cassettes fit SureLock™ tanks and are compatible with NuPAGE buffers. This allows a cost effective trial or switch to RunBlue Bis-Tris. A 5 gel trial box is available at the same cost per gel as the standard pack of 10.

With British precast gels

Bis-Tris RunBlue gels are developed and manufactured in Cambridge, UK. This lets Expedeon to provide fast delivery without any back orders. Using RunBlue will reduce the carbon footprint associated with transportation, as well as decreasing shipping costs.
