Abstract
Whole mount immunofluorescent analysis of human cortical kidney slices
Procedure
- Carefully decapsulate the fresh kidney tissue in 1xPBS. The capsule interferes with antibody access. Be careful to not disturb the underlying tissue.
- Place surgical gauze in 10cm Petri dish and fill the Petri dish with 1xPBS. Place the kidney on the wet surgical gauze. With a pair of blunt-ended forceps hold the kidney and with the other hand slice off approximately 3mm thick cortical slices – note, these are fragile.
- Fix kidney slices in 4% PFA in 1xPBS for 45 minutes at 4˚C without shaking. Wash out the PFA with several rounds of 1xPBS.
- Block the slices for 1hr. in 1xPBS with 2% SEA Block and 0.1% TritonX100 at 4°C with gentle movement (e.g. on a Nutator).
- Resuspend the primary antibody in blocking solution and incubate in primary antibody at 4°C with gentle movement for 48 hr.
- Wash samples for up to 8 hr. through several rounds of 1xPBS with 0.1% TritonX100.
- Resuspend the secondary antibodies in blocking solution and incubate the sample in secondary antibodies at 4°C with gentle movement for 48 hr.
- Repeat the washing steps and place in 1 µg/ml Hoechst 33342 for 2 hr. before a final wash in 1xPBS.
- Dehydrate the sample prior to clearing by passing the sample through a series of increasing concentrations of methanol (50%, 75%, 100%) 1 hr. for each.
- To clear specimens there are a number of options. For example, place the dehydrated tissue in a 50% Benzyl alcohol, Benzyl benzoate (BABB – note BABB is toxic) / 50% methanol solution for an additional hour.
- Replace with 100% BABB.
- Store sample at 4˚C in the dark until ready to image.
- Image as appropriate (e.g. on a confocal microscope).
