The neutralizing effects of affinity purified egg yolk anti-IL-10 antibody were
determined by measuring the ability of recombinant chicken IL-10 to inhibit
IFN-γ production in Concanavalin A (Con A) stimulated chicken splenocytes.
Splenocytes were untreated, stimulated with 20 μg Con A, stimulated with Con A
and 0.2 ng/mL, recombinant chicken IL-10, or stimulated with Con A, IL-10, and
0.85 μg/mL affinity purified egg anti-IL-10 specific antibody. Culture
media was analyzed for IFN-γ 24 hours after treatment. Anti-IL-10 was effective
at neutralizing IL-10s inhibition of IFN-γ release (overall ANOVA
P < 0.0001, standard error of the mean bars n = 3).
a–dTreatment means with different letter superscripts are
statistically different (P < 0.05).
