The first covers the introduction of nitrogen-containing functional groups by amination of carbon-based nucleophiles.

13]C NMR method suits best for determination of different functional groups derived from F [9,10].

Thousand Oaks, CA) has patented a process for separating a target protein (such as a recombinant protein produced in a cell culture) from a mixture containing the target protein and contaminants (such as cell culture contaminants), by contacting the mixture with a hydrophobic adsorbent comprising branched hydrocarbon functional groups in an aqueous salt solution and collecting the unbound flow-through fraction containing the target protein.
