From: Assessment of T-dependent and T-independent immune responses in cattle using a B cell ELISPOT assay
Kinetics of TNP- and TTC-specific IgG titres following primary and boost TTC immunisations. TNP-specific IgG titres in calves from the T-D group (open diamonds) or T-I group (filled diamonds) and TTC-specific IgG titres in all calves (cross symbols) were determined by ELISA. The dotted vertical lines indicate when the primary and boost TTC immunisations were administered (days 134 and 197 pi, respectively). Results are expressed as the mean of determinations from individual calves in each group for the TNP-specific responses (n = 5) and the mean of determinations from all calves for the TTC-specific responses (n = 10).
