ABSTRACT

We have developed a method based on self-assembly of thiols on Au substrates to immobilize membrane proteins at interfaces. Using water soluble nitrilotriacetic acid (NTA)-terminated oligo(ethylene glycol) thiols, a histidine-tagged G protein-coupled membrane receptor (GPCR) was captured in a defined orientation with little nonspecific binding.
