Description Ciphergen's ProteinChip arrays have been developed for affinity capture of proteins from biological samples. A variety of ProteinChip chemical surfaces allow differential capture of proteins according to their unique biochemical properties. Each chip has eight different spots, allowing side-by-side sample comparison, and the chips are color-coded with a unique hydrophobic coating. Ciphergen's proprietary chip technology thus allows the researcher to rapidly capture, purify and characterize proteins directly on the chip.
Cationic arrays bind proteins through electrostatic interaction of positively charged amino acids such as lysine, arginine and histidine. Binding occurs at low pH with low salt; binding decreases as pH and salt concentration increase.
ProteinChip WCX2: is a weak cation exchange array with a carboxylate surface to bind cationic proteins. The negatively charged carboxylate groups on the surface of the WCX2 chip interact with the positive charges exposed on the target proteins. The binding of the target proteins is reduced by increasing the concentration of salt or by increasing the pH of the washing buffers.
