Conservation, reconstitution and concentration of peptides
Resolves doubts about dry material, solutions, transportation and units. The reference and assay protocol determine what conditions can be used.
Preparing a sample changes the stability questions. Differentiates dry and solution state, records conditions and uses final mass and volume to calculate nominal concentration. The appearance of the vial does not quantify its contents; The calculator does not select a solvent or set administration doses.
