An investigator requested the following info. I want to show by FACS that a protein is cell surface expressed. In western blotting reduction is required for detction of this epitope tag, indicating Ab inaccessiblity in 3D structure. Are there any methods to partially disrupt cell surface proteins, and hence detect this epitope, while maintaining cell viablility for FACS ? Any info would be greatly appreciated. Thanks in advance.
