The extracellular domain of recombinantly-produced mouse VSIG4 was used to immunise an alpaca (Vicugna pacos). Peripheral blood lymphocytes isolated from the immunised alpaca were used to generate a Nanobody phage library, clones from which were selected for binding to the same recombinant mouse VSIG4 extracellular domain.
