WebThe blue blood of the horseshoe crab is a natural, irreplaceable, and precious resource that is highly valued by the biomedical industry. The Limulus amebocyte lysate (LAL) obtained from horseshoe crab blood cells functions as a surprisingly sophisticated sensing system that allows for the extremely sensitive detection of bacterial and fungal cell-wall … Webedition of the LAL Update(2).) Dilution is the simplest and most widely used technique for overcoming interference, and it is effective in the majority of cases. The MVD (i.e. the scope for dilution) can be increased by changing to a more sensitive LAL reagent or test method. Dilution should be tried before other methods of addressing interference. The LAL test is a major source of animal product dependence in the biomedical industry, and a challenge to the Three Rs of science in relation to the use of animals in testing. With reports of higher-than anticipated mortality rates it has been considered more ethical to devise alternatives to the test. Since 2003, a recombinant protein substitute for use in the LAL test has been commercially available. Named the recombinant factor C (rFC) assay, it is based on the same Li… celery beat_schedule args
