| abstract |
The invention relates to, inter alia, a fusion protein comprising a protein of interest and an affinity tag which binds lysozyme. Lysozyme can be used to purify, precipitate, or support the crystallization of such a fusion protein. The invention further relates to a binding agent which specifically binds a target compound, wherein the binding agent has a CDR3 region which is derived from a single-domain antibody but which does not comprise framework regions or other elements for stabilizing the CDR3 region, and wherein the binding agent binds the target compound via the CDR3 region. |
