Figure 1:
Analysis of blood plasma taken from nurse shark ‘Orange’ before immunization (pre-bleed) and following induction of a primary response (bleed 4) demonstrates (A) a robust HEL-specific IgM response and (B) low level IgNAR response by antigen-binding ELISA. Results shown are duplicate averages. Control wells were both coated and blocked with 5% MPBS.
