Article Correctness Is Author's Responsibility: Zombie scanning enables the study of peptide-receptor interactions on the cell surface

In the past, biologically-active peptides -- small proteins like neurotoxins and hormones that act on cell receptors to alter physiology -- were purified from native sources like venoms and then panels of variants were produced in bacteria, or synthesized, to study the structural basis for receptor interaction. A new technique called zombie scanning renders these older processes obsolete.
