We're certain that you can get better sequence coverage and identify more proteins from your complex protein mixtures. Send in your sample and we'll show you how, for free.

This is a limited-time, free offer for researchers who analyze proteins using mass spectrometry. Please, just one sample per lab.

What we'll do:

Send in your complex protein mixture sample, and we'll:

• Fractionate it by size
• Recover 12 liquid-phase fractions
• Remove the SDS
• Visualize the 12 fractions on a gel with an unfractionated control lane and a MW standards lane
• Digest the 12 fractions with trypsin (optional)
• Generate a base-peak chromatogram from an aliquot of one of the digested fractions
• Save the fractions, and any remaining unprocessed sample, for you on dry ice

What you'll get:

Here's what you'll get when you send in your sample:

• A copy of the protocol we used
• An image of the gel with your sample fractions
• A report with the results of the mass spectrometry analysis
• Your sample fractions, and any remaining unprocessed sample, returned to you on dry ice

Why we're doing this:

We want you to send in your sample so we can show off the benefits of using the Gelfree 8100 Fractionation System for complex protein mixture fractionation. Simply put, the Gelfree System reduces sample complexity and provides more protein for a clearer, stronger, mass spec signal. We're sure you'll see a dramatic improvement in data quality. The Gelfree System:

• Fractionates intact proteins by molecular weight
• Recovers liquid-phase fractions without gel cutting
• Offers three times greater protein recovery than a 1-D gel
• Can handle five times the loading capacity of a 1-D gel
• Produces samples optimized for SDS removal and MS analysis
• Enables highly efficient liquid-phase trypsin digestion

Q&A about this free offer:

Who can benefit from this offer? Any proteomics research scientist applying bottom-up or top-down analysis methods will appreciate the benefits of this free sample workup offer, including reduced sample complexity and stronger, clearer, mass spectrometry signals.

Is it really free? Yes. All we ask is that you fill out the form and take care of one-way delivery when you send in your sample. We'll do the sample workup, gel imaging, mass spec analysis, and analysis report, and send it all back to you, along with your fractionated samples on dry ice.

Then what? You won't be obliged to pay for anything or buy anything. This free offer is our way of getting the word out about Gelfree technology and the Gelfree 8100 Fractionation System.

How long does it take? We'll send you your results and your fractionated samples ten business days after you send in your sample, or sooner.
