The blood is placed in the centrifuge to separate the amoebocytes through the blue haemolymph that comprises the supernatant.
A different influence of interference is endotoxin masking, causing challenges including reduced endotoxin Restoration (LER), which can be a result of the dissociation with the supramolecule assembly of LPS during the presence of surfactants and chelating agents. The phenomenon of LER was originally described in the therapeutic items of monoclonal antibodies in April 2013, and also the FDA has regarded as LER being a possible safety challenge owing for the likelihood of Wrong-unfavorable test final results.
