Phosphate Buffered Saline in Peptide Research: The Reagent That Decides Whether a Result Is Reproducible
Buffer is the least examined component of most peptide experiments. The peptide is characterised, documented and recorded by lot. The vehicle it is dissolved in is noted as phosphate buffered saline, or frequently as PBS, and treated as a constant. It is not a constant. It is a formulated reagent whose composition varies between preparations,
