This category is reserved for sites demonstrating specialism in identifying and quantifying the protein composition of cells, organelles or other biological sample. For sites offering only the analysis of peptides following digestion of intact protein, consider submitting the site to Peptides . . Services. For mass spectrometry facilities aimed at a broader sample or client base, consider Mass_Spectrometry . . Services instead. (Duplicate submissions will be deleted)
Sites offering analytical services on submitted samples, to identify and determine relative concentrations and bioactive status of proteins expressed in biological samples.
