"I don't see why the customer — in this case the E.U. — should accept a diktat from the seller to allow contamination with products that have not been approved as safe in Europe," a Greenpeace activist on agriculture issues, Marco Contiero, said.
Failure to do this would allow contamination of the experiment with MMP-2 containing serum.
The conclusion was that sources of contamination could be identified and eliminated, allowing contamination-free assays to be conducted [ 36].
Indeed, the "extract clarification" centrifugation step allows avoiding contamination with other than microtubules macromolecular complexes and organelles, but at the same time removes large protein complexes, such as known to exist for proteins like NUMA [43].
Blue-green algae such as A. flos aquae marketed as dietary supplements are commonly grown in open, natural environments which allows for possible contamination with toxin-producing cyanobacteria. A. flos aquae has the ability to produce a multitude of toxins including anatoxin-a, saxitoxins, cylindrospermospin, and BMAA, in addition to microcystins [ 5].
Court-appointed experts said that the DNA had been collected in a way that could have allowed for contamination, and that the genetic information on two main pieces of evidence could not be matched to the defendants with certainty.
First, the relatively short median length of ICU stay (eight days) did not allow heavy contamination of the environment with MDRO.
One intervention promoted was the freezing of fresh poultry meat to reduce levels of Campylobacter spp. contamination, with fresh poultry allowed to be sold only when it could be shown to pose a low risk to human health (5, 14).
The investigated contamination with hydraulic oil allows only a clear differentiation between cleaned and contaminated.
Plotting data with respect to the first three PCs is useful to identify the spatial variability of soil contamination with Hg and allows grouping sites with similar contamination factors.
