Figure 2. Production of nanobody from SAβO-injected alpaca.
(A) Coomassie stained SDS-polyacrylamide gel, and (B) Western analysis to confirm the production of the low molecular weight SAβOs (16 kDa) and some higher molecular species. Lanes 1 and 2 are from two different SAβO preparations; lane 3 is from free Abeta peptide. (C) General procedures for generating antibodies/nanobodies after immunization of alpaca with SAβO antigen. (D) Dot-blot analysis showed that the plasma from the alpaca immunized with SAβO (CaLee) recognizes SAβO antigen, while no response was observed for other non-immunized alpacas (Twelve, Sweety Pea, Grand Design, and Princess Fawn).
