Recently, I began working in a lab in which our main area of study is Aβ peptides. My concern is whether or not exposure to high levels of Aβ proteins is hazardous.
I suspect that the peptides cannot pass through one's dermis, but this is just speculation. Also, if one were to accidentally ingest Aβ, it would likely be broken down into its monomers by your digestive system before it could cause any harm.
I've tried to find resources covering my concerns but to no avail.
