Protein targets can be readily detected and localized with single molecule resolution and objectively quantified in unmodified cells and tissues.Molar mass distribution: In linear polymers the individual polymer chains rarely have exactly the same degree of polymerization and molar mass, and there is always a distribution around an average value. The molar mass distribution (or molecular weight distribution) in a polymer describes the relationship between the number of moles of each polymer species (Ni) and the molar mass (Mi) of that species.DNA condensation: DNA condensation refers to the process of compacting DNA molecules in vitro or in vivo.
