Fig. 1. Northern blot hybridizations of occludin, claudin-1 and ZO-2 mRNAs in the periimplantation mouse uterus. The mRNA levels were detected in total RNA samples obtained from whole mouse uteri from days 1-8 of pregnancy. A 2.3 kb transcript for occludin, a 4.0 kb and a 1.5 kb transcript for claudin-1, and a 5.2 kb transcript for ZO-2 were detected in the uterus. The blot was hybridized with rpL7 to confirm integrity, equal loading, and blotting of RNA samples.
