Experiment Name: SDS-PAGE and immunoblotting
1. To determine whether there are developmental claudin isoforms, Ghazala et al. compared the claudin isoforms present in the neonatal and adult kidney using RT-PCR to detect mRNA of claudin isoforms. Claudin 6, claudin 9, and claudin 13 were either not expressed or barely detectable in the adult mouse kidney using traditional PCR, but were expressed in the neonatal mouse kidney.
2. Using real-time RT-PCR, we were able to detect a low level of claudin 6 mRNA expression in the adult kidney compared with the neonate, but claudin 9 and claudin 13 were only detected in the neonatalkidney. There was the same maturational decrease in these claudin proteins with Western blot analysis.
3. Claudin 9 was only consistently detectable in proximal convoluted tubules of 1-day-old neonates and only after more than 35 cycles of amplification. Claudin 13 was not detectable. It is possible that claudin 9 and 13 play a role in determining neonatal paracellular permeability in a distal nephron segment.
1. Neonatal and adult kidney protein (100 ug/lane) were denatured and separated on a 6% polyacrylamide gel using SDS-PAGE.
2. The proteins were transferred overnight to a polyvinylidene diflouride membrane at 120-140 mA at 4 C.
3. The blot was blocked with fresh Blotto (5% nonfat milk and 0.1% Tween 20 in PBS, pH 7.4) for 1 h followed by incubation with overnight at 4 C with a primary antibody to mouse claudin 6 (Orbigen, San Diego, CA) at a 1:5,000 dilution, claudin 9 (Aviva Systems Biology, San Diego, CA) at 1:1,000 dilution or claudin 13 (Zymed Laboratories, South San Francisco, CA) at 1:100 dilution.
4. The blot was then washed extensively with Blotto.
5. The secondary antibody, horseradish peroxidase-conjugated donkey anti-rabbit immunoglobulin, was added at 1:10,000 dilution and incubated at room temperature for 1 h.
6. The blot was again washed with Blotto, and enhanced chemiluminescence was used to detect boundantibody (Amersham Biosciences, Piscataway, NJ). Claudin 6, 9, and 13 protein abundance was quantitated using densitometry.
7. Equal loading of samples was confirmed using an antibody to -actin at 1:5,000 dilution (Sigma Biochemicals, St. Louis, MO). There were at least six samples in each group.
