IgG2 antibody | IL-A73
Horseradish peroxidase conjugated Mouse anti Bovine IgG2 antibody, clone IL-A73 (MCA2441P) used to evaluate bovine IgG2 levels in serum samples by ELISA.
Image caption:
Antibody profile of S19 and RB51 prime vaccinated, and RB51 revaccinated cattle measured by I-ELISA using S19 and RB51 whole-cell antigens.
The results are expressed as mean. Data for total IgG, IgG1 and IgG2 are shown. Vaccinations were indicated by arrows. Lowercase letters indicate statistical difference between days on same group (one-way ANOVA followed by paired t-test).

Antibody Quality and 
Unrivaled 
| Mouse anti Bovine IgG2, clone IL-A73, is a monoclonal antibody specific for bovine IgG2 and does not recognise other bovine immunoglobulin classes. While normal serum levels of IgG1 are relatively constant in cattle at around 50%, IgG2 levels are highly variable between different strains and races. Mouse anti Bovine IgG2, clone IL-A73 immunoprecipitates a protein band of approximately 52-59kDa, consistent with the heavy chain of bovine IgG2 (Campbell et al. 1998). |
