Fig. 5. Localization of Mlh1 in Brca1 mutant mice. (A,B) Scp3 and Mlh1
double immunofluorescence staining of chromosomes prepared from
p53+/- control (A) and
Brca1
11/
11p53+/- mutant (B)
spermatocytes at the pachytene stage. Three pairs of mutant and control mice
at P16, P18 and P21 were examined. There were no significant differences in
Mlh1 foci formation between Brca1 mutant and control mice in
(P
0.0001). (C) Scp3 and Mlh1 double immunofluorescence
localization of chromosomes prepared from
Brca1
11/
11p53+/- oocytes. More
than 10 mutant and control embryos at E16.5-17.5 were examined and no obvious
differences were found. (D) Western blot analysis of Mlh1 and Pms2 in
p53+/- (C) and
Brca1
11/
11p53+/- (M) testes.
Genotypes, ages and antibodies are indicated.
