Analysis of human ALB in the blood.
(a) Western blot detection of human albumin in the blood of founder piglets. 0.5 μl plasma from each founder was separated on SDS-PAGE and analyzed. Human blood plasma (0.5 μl after diluted 30 times) was used as a positive control. C, plasma from a wildtype pig. (b) Illustration of tryptic peptides (green) detected with mass spec analysis. (c) Semi-quantitation of two tryptic peptides from human and pig albumin through measuring the peak areas of each peptide. Red marks the amino acid residues that are specific to pig.
