Allergenic Potency of Lantana pollen extract and its major allergen. a Specific IgE ELISA. Dot plot showing the distribution of group specific IgE titers among 15 patients due to crude allergen extract along with IgE titers. b Stripped basophil histamine release assay. Grouped distribution showing histamine release due to crude allergen; control and BSA: Negative control. Statistical analysis: two-way ANOVA employing Bonferroni multiple comparisons test. *Represents significance at p < 0.05. Specific IgE titers were significant in pairs and across columns. Patients of Group 1 (1, 8, 15, 12, 10, 14) showed elevated histamine release compared to others. c Linear regression model following Spearman’s correlation of total histamine release in cell and sIgE-ELISA of Lantana camara. Correlation coefficient (r) value: 0.8007; p value: 0.003 where correlation is significant <0.005 level
