Immunohistochemistry analysis of SGK1 (PS422) showing staining in the cytoplasm of paraffin-embedded human kidney tissue (right) compared to a negative control without primary antibody (left). To expose target proteins, antigen retrieval was performed using 10mM sodium citrate (pH 6.0), microwaved for 8-15 min. Following antigen retrieval, tissues were blocked in 3% H2O2-methanol for 15 min at room temperature, washed with ddH2O and PBS, and then probed with a SGK1 (PS422) Rabbit Polyclonal Antibody (441264G) diluted in 3% BSA-PBS at a dilution of 1:20 overnight at 4°C in a humidified chamber. Tissues were washed extensively in PBST and detection was performed using an HRP-conjugated secondary antibody followed by colorimetric detection using a DAB kit. Tissues were counterstained with hematoxylin and dehydrated with ethanol and xylene to prep for mounting.

Serum and glucocorticoid-regulated protein kinase 1 (SGK1) is a member of the AGC family of serine/threonine kinases that plays an important role in cellular stress response and cell survival. SGK1 is transcriptionally activated by numerous stimuli, including serum, glucocorticoids, osmotic stress, and hormones. SGK1 functions as a regulator of cell survival and ion channels and transporters such as ENaC or KCNA3/Kv1.3. It phosphorylates and negatively regulates pro-apoptotic FOXO3A. SGK1 is thought to play an essential function in nephropathy and cardiovascular development.
