IgGa antibody | CVS48
Mouse anti Horse IgGa antibody, clone CVS48 (MCA1902GA) used for the evaluation of equine IgG1 serum levels by ELISA.
Image caption:
Vaccination significantly increased serum titers of IgA, IgG1, and IgG4/7.
Optical density ratios from serum samples relative to a positive control of IgA (panel A), IgG1 (panel B), and IgG4/7 (panel C) antibodies among IM-only vaccinates (Group = Vx; n = 20) and controls (Group = C; n = 10). The bottoms and tops of the boxes represent the 25th and 75th percentiles, and the horizontal lines in the boxes represent the medians; the thin vertical lines extend to a multiple of 1.75 of the respective interquartile distance, and the small circles represent outliers. Asterisks indicate significant (P <0.05) difference from baseline (Week 0) among vaccinates. For IgA (Panel A), concentrations were significantly higher than baseline through week 11 after initial vaccination (12 weeks after booster injection); for controls, there were no significant differences in titers at any of the time point comparisons. For IgG1 (Panel B), concentrations were significantly higher than week 0 from weeks 3 through 11, and again at week 27. For controls, values at week 27 were significantly (P <0.05) higher than for all other times, but no other differences were significant. We attributed the higher titers at week 27 in both groups to be attributable to an artifact of testing or acquisition of natural antibody to PNAG. For IgG4/7 (Panel C), concentrations were significantly higher than week 0 from weeks 3 through 15; for controls, there were no significant differences among times.
