Hi Helmut,

❝ ❝ A dumb question …

Just a way to catch your attention

❝ Are you talking about a drug with protein binding? That’s easy. Protein binding is caused by Van der Waals force, which is extremely weak. In a nutshell, in any extraction (liquid-liquid, solid-phase), or protein-precipitation the protein-drug bonds will be practically imme­dia­tely cleaved and therefore, from the extract you get always the total concentration.

Yes, according to the text it was protein-precipitation extraction from plasma during sample pre-treatment phase. It's a drug w high protein binding. So it's total drug?

Thx
J
