In vitro affinity maturation
WebStep 1: A library of rearranged light chains is created in the phage display vector pHEN1-Vλ3. Step 2: A wild-type V H gene is cloned into the light-chain library to create a light chain-shuffled library. Higher-affinity scFv are isolated from the light chain-shuffled library by panning.
