产品描述
应用
The Protein A molecule contains four high-affinity (Ka =108/mole) binding sites capable of interacting with the Fc region from IgG of several species including human and rabbit. Optimal binding occurs a pH 8.2, although binding is also good at neutral or physiological conditions (pH 7.0-7.6).
使用说明
This material is offered by Sangon Biotech for research, laboratory or further evaluation purposes. NOT FOR HUMAN USE.
