PISA of nine human VH/K-His
fragments from a transgenic mouse library (12).
(A) Analysis with biotinylated P-BSA, followed
by HRP-linked streptavidin. (B) The same array
after treatment with stripping buffer and re-analysis with HRP-linked
anti-human κ chain. Wells 1–5,
non-antigen binding VH/K-His fragments from
clones of the transgenic mouse library; P5-8, -10, -16, -17, specific
anti-progesterone VH/K-His fragments from the
same library; Con, TNT mixture control lacking PCR DNA.
