Peptides and mimetics of selected domains of mammalian serum amyloid A isoform 2. A metal cap layer is formed over conductive lines to prevent oxidation of the conductive lines during subsequent processing steps. The solution is then coated on a predetermined portion of a substrate by the ink-jet apparatus. A female thread diameter varies according to a position in an axial direction of the ball nut. Similar workflow can be employed for estimating contamination at the end of cleanup production for a given pumpout volume.
