This thesis aims to investigate if the endothelial protein C receptor is expressed in the murine kidney. This was done by performing flow cytometry and Western blot analysis on cultivated murine kidney endothelial cells (mKECs) as well as SDS-PAGE and Western blot analysis on murine kidney tissue. Flow cytometry was also performed on cultivated ARPE19 and 4T1 cells for comparison. It was discovered that ≥95,5% of the mKECs, ≥93,6% of the ARPE19 cells and ≥60,9% of the 4T1 cells express the receptor according to the flow cytometry data. A dot blot was performed to validate the primary antibody used for detection of EPCR in Western blot and SDS-PAGE. According to the dot blot, the primary antibody can be visualised in the dilution range from 1:2000 to 1:10. The dot blot also showed that the secondary antibody binds specifically to the primary antibody. Yet, Western blot analysis did not detect the receptor neither in mKECs nor tissue lysate. This was likely due to the fact that the primary antibody used did not bind specifically to the receptor, and may not be applicable for this method. SDS-PAGE did not show any indication that the receptor was present in the kidney tissue. In conclusion, it was discovered that the EPCR was expressed in the murine kidneys endothelial cells through flow cytometry, but the presented methods for Western blot and SDS-PAGE could not confirm the expression of the receptor.
