AES : Superior lot to lot consistency, QC with customers’ sample and customers’ criteria
Conventional: Difficult to implement and time consuming to utilize as product quality control method
AES : Help customer to accelerate method R&D
Conventional: Interaction with proteins causes irreproducible focusing pattern
AES : Customized CAs for specific molecule

pI Markers

IEF reference standard pI markers are essential for calibration of the isoelectric point (pI) of proteins in CIEF.

AES has developed the most comprehensive pI markers in the world. These pI markers are ready to dilute 100 times into a sample and carrier ampholytes mixture for protein pI calibration, confirmation of pH gradient linearity, and CIEF process control. To facilitate accurate and reproducible pI calibration, at least one CEInfinite pI marker is provided within each 0.5 pH unit. Small peptide pI markers may be degraded in the presence of enzyme, which interrupts protein assays.

AES provides selection of pI markers from p 2.85 to 10.45 that resist to enzyme digestion. CEInfinite pI markers are provided in a variety of package sizes and have long shelf lives, which make it easy for you to reduce potential waste and save your restocking time.

Cartridges

High-Sensitive, High-Performance Imaging CIEF Cartridges for multi-purposes

Proprietary separation column modification with hydrophobic fluorocarbon or hydrophilic coating selections.

WCID-iCIEF cartridges for easy direct coupling to a Mass Spectrometer. The world’s only WCID-iCIEF cartridges for preparative CIEF.

Sensitivity improvement of 200 μm id WCID cartridges is 100% over those of 100 μm id with lower resistance for sample injection, less clogging.
