Human proteins in pig plasma after BAL treatment.

<p>Pig blood samples were assessed by ELISA for specific human protein content during treatment; Group 1 cell bead treated BAL (solid symbols), compared with Group 2 empty bead control treated BAL (open circles) (<b>A</b>) Albumin (<b>B</b>) Fibrinogen, (<b>C</b>) Alpha-1-acid glycoprotein (A1AGP) and (<b>D</b>) Alphafoetoprotein (AFP). Results expressed as µg/ml pig plasma: mean±SEM n = 6. No human protein was detected in Group 2 animals, establishing the specificity of the assays for human proteins.
