Poor air permeability
WebThe permeability assays showed that palytoxin could not significantly pass the Caco-2 monolayer despite the lack of epithelium integrity, suggesting that, palytoxins would be poorly transported to blood, which can explain its lower oral toxicity. These data can help to achieve a better understanding of palytoxin poisoning. WebCleans best at 90-100 psig air. Tubular Woven Bags: Open top; closed bottom; mounted to wire cages.
