Endotoxin content of corn starch and Holi colours 1–4. The endotoxin content of corn starch and Holi colours 1–4 was determined by LAL test. The resulting endotoxin amount was measured in Endotoxin Units per ml (EU/ml). Samples were applied in the same concentration as used for stimulation of PBMCs (corn starch and Holi colours 1–4: c = 1.5 × 106 particles/ml, LPS: 100 ng/ml)
