CEInfinite iCIEF Solutions

CEInfinite AESlytes Carrier Ampholytes

Carrier ampholytes are essential for isoelectric focusing (IEF) separation of proteins. 

Since early Carrier ampholytes were developed before the introduction of imaged capillary IEF (iCIEF), the unique requirement of low UV absorbance could not be applied in iCIEF application. In addition, interaction of Carrier ampholytes with protein in gel media and solution phase is different. Therefore, it is advantageous to have Carrier ampholytes for iCIEF with low protein interaction in solution phase for reproducible iCIEF protein separation and with low UV absorbance for minimised electropherogram baseline noise.

AESlytes are composed of a remarkably high percentage of effective Carrier ampholytes (CAs) with small ΔpK, which provides faster focusing and more stable pH gradient.

Proteins are so complex, and they react differently with CAs, depending on the functional groups of CAs. Therefore, we developed three series of AESlytes that possess different basic functional groups to minimise protein interaction. AESlytes are available in High Resolution (HR), Super High (SH) and Ultra High (UH) resolution series.

The AESlytes Carrier ampholytes were developed specifically for protein high performance iCIEF separation based on our extensive research. Our AESlytes meet all the requirements of good carrier ampholytes:

  • Good pH linearity
  • High buffering capacity
  • Good stability
  • Insignificant interaction with proteins in the sample
  • Low UV absorbance
  • Use at very low concentration for MS detection

In addition we offer custom-made AESlytes CAs to help you with achieving higher resolution of your iCIEF and/or IEF 
assays. We understand your requirements. Please don’t  hesitate to contact us.
