1.   The antibodies are protein molecules that can fit on to an allergen and inactivate it.

2.   The virus develops most quickly when antibodies are absent.

3.   Similar procedures were carried out as described above except that the secondary antibody was rabbit antibody to human immunoglobulin conjugated with peroxidase instead of alkaline phosphatase.

4.   Locally produced polymeric IgA antibodies may therefore be the principal immune stimulator of eosinophil effector functions at mucosal surfaces, both in protective and tissue destructive situations.

5.   Both antibodies are a largely heterogeneous family.

6.   In conclusion, our study confirms that perinuclear antineutrophil cytoplasmic antibodies are indeed demonstrable in the large majority of ulcerative colitis patients.

7.   Other reports also suggest that in this disease there are circulating antibodies against antigens common to biliary and colonic epithelia.

8.   Alkaline-phosphatase-conjugated antimouse or antirat lgG antibodies were from Sigma.

9.   Although vaccinated people made antibodies to that protein, the antibodies were all but useless because the virus mutated constantly, altering its surface protein and evading the antibodies.
