Adsorption to container surfaces and to plastics — setting out what I have, and where I think it stops being reliable.

Adsorption — I have the observation and I do not trust my interpretation of it, so I am posting the observation and holding the interpretation back.

Numbers, method and the conditions under which they were collected are below. Interpret them however they warrant.

Appreciated. The plain phrasing does more work here than a longer post would.

Worth separating two things that the opening post runs together.

Surfactants such as polysorbate are added to prevent adsorption and aggregation at interfaces. In a bare research preparation there is nothing performing that function.
