Principal component analysis of 12 measures of immune response from the 200 animals immunized with KLH (Group A): variance explained by the first 5 axes (PC1 to PC 5) and relative contributions of the 12 variables to each axis

Trt_Init = Antibody (Ab) titer before immunization with KLH, Trt_Final = Ab titer after immunization with KLH (Group A), LPS-Init = Nabs to LPS at day 0, LPS_Final = Ab to LPS 7 days post immunization, LTA_Init = Nabs to LTA at day 0, LTA_Final = Ab to LTA 7 days post immunization, Gal*2_Init = Ab to anti-Gal epitope at day 0, Gal*2_Final = Ab to anti-Gal epitope 7 days post immunization, D_Trt = responsiveness of Ab response to M.B, D_LPS = responsiveness of Ab response to LPS, D_LTA = responsiveness of Ab response to LTA, D_GAL = responsiveness of Ab response to anti-Gal.
