Fig. 3. Immunoblot analysis of (A) antibody specificity and (B)
immunocrossreactivity of PCBP-25
and PCBP-25ß. Samples were
subjected to SDS-PAGE, transferred to nitrocellulose and probed with either
polyclonal antibody against Chlamydomonas centrin or with monoclonal
antibody 7A9 as indicated. (A) Lane C, Chlamydomonas whole cell, 15
µg; lane P, quick-killed Paramecium, 20 µg. (B) MonoQ fractions
(20 µl) containing PCBP-25. Fraction numbers are indicated at the bottom of
the blot. M, Mr of markers (x103).
