So the same as these “dwelling fossils” have graced the oceans for numerous yrs, with treatment they're able to continue on providing their precious blood for medical breakthroughs effectively into the long run.
Furthermore, it could even be much better than LAL in several facets. LAL may lead to possible Bogus negatives because its sensitivity can be inhibited by numerous buffers and solvents (Maloney et al
