Evidence of the action of the amoebocytes and the participation of different lectins in binding the larvae of the trematode with the amoebocytes (Martins-Souza et al., 2006) can be tested by the technique of cultures of the amoebocyte producing organ (APO) as first described by Barbosa et al.
Endotoxin analysis is usually carried out using the Limulus Amoebocyte Lysate (LAL) assay.
Purity was assessed by endotoxin content (determined by chromogenic endotoxin assay, using a modified limulus amoebocyte lysate and a synthetic color-producing substrate), which was considered acceptable in concentrations <0.1 IU/mL.

MAFF scientists have published the protocols for four fully-validated tests: detection of irradiated herbs and spices using thermoluminescense technology; detection of irradiated bone-containing meat using electron spin resonance spectroscopy; detection of irradiated food containing fat by using 2-alkylcyclobutanone markers; and detection of irradiated poultry meat using the Limulus Amoebocyte Lysate test in conjunction with a gram-negative bacterial count.
