ZOOM® Carrier Ampholytes are small, soluble molecules with both positive and negative charge groups. They sort based on their isoelectric points in an electric field, thereby establishing a pH gradient in solution or contributing to the gradient when used with IPG strips. Carrier ampholytes help stabilize the pH gradient and current in IPG strips and aid in protein solubility, resulting in reproducible IEF resolution.

常见问题解答 (FAQ)

When running the ZOOM IEF Fractionator, if there is not a solubility issue, will the proteins/peptides in the sample migrate to their expected chambers based on isoelectric point in the absence of carrier ampholytes? Won't they act as ampholytes within each chamber?

Proteins are ampholytes, but in general they are poor carrier ampholytes. The profiles of the fractions are similar, but not identical, to those obtained with ampholytes in the sample.

Can I heat my protein sample prepared using ZOOM 2D Protein Solubilizer?

We do not recommend heating protein samples containing urea over 37 degrees C as elevated temperatures cause urea to hydrolyze to isocyanate, which modifies proteins by carbamylation.

How do you recommend storing protein samples prepared in the Sample Rehydration buffer?

We recommend storing them at -80 degrees C. We do not recommend storing them at -20 degrees C

How much ampholyte do you recommend adding to the sample rehydration buffer?

The recommended ampholyte concentration in the sample rehydration buffer is 0.5%.

*If you are loading 5-50 µg of protein (pure protein or crude lysate) per ZOOM strip, use 0.5% ampholytes in the sample rehydration buffer.
*If you are loading >50 µg of protein (crude lysate or fractionated sample) per ZOOM Strip, use 0.5-2% ampholytes in the sample rehydration buffer.

Note: Higher ampholyte concentration requires longer focusing times.

What is the maximum recommended volume of protein sample to be added to the Sample Rehydration buffer?

The maximum volume of the protein sample should at most be 1/6 of the final sample volume that will be added to the strip. A good general volume would be 5-10µL. 140 µL of sample diluted in Sample Rehydration buffer is used to rehydrate each ZOOM Strip for the standard rehydration time of one hour. For overnight rehydration, we recommend using 155 µL of diluted sample.
