Neutrophils more successfully engulf beads when the embedding agarose gels are made with low concentrations of agarose. At 0.3% agarose, an average of 28% of neutrophils had internalized beads. For all other agarose concentrations, fewer than 2% of neutrophils had internalized beads. Error bars are standard error of the mean. Single-factor analysis of variance gives a p-value of 0.002.
