REDD-1 Antibody / mTOR Signaling Regulator Antibody (F54848)

REDD-1 Antibody Human Adenocarcinoma IHC. IHC staining of FFPE human adenocarcinoma tissue with REDD-1 antibody demonstrated cytoplasmic staining in malignant epithelial cells, consistent with the expression pattern of REDD-1 (DDIT4), a stress-responsive regulator of mTOR signaling. REDD-1 is induced by hypoxia, oxidative stress, DNA damage, and metabolic challenges, where it functions to suppress mTOR activity and promote cellular adaptation to adverse conditions. The staining observed within tumor cells is consistent with activation of stress-response pathways commonly associated with the tumor microenvironment. Heat-induced epitope retrieval was performed by steaming tissue sections in pH 6 citrate buffer for 20 minutes and allowing them to cool prior to staining. These results support the utility of REDD-1 Antibody for studies of hypoxia signaling, mTOR pathway regulation, cellular stress responses, and cancer biology.

REDD-1 Antibody Human Kidney IHC. IHC staining of FFPE human kidney tissue with REDD-1 antibody demonstrated strong cytoplasmic staining of renal tubular epithelial cells, consistent with the expression pattern of REDD-1 (DDIT4), a stress-responsive regulator of mTOR signaling and cellular metabolism. REDD-1 is induced by hypoxia, oxidative stress, nutrient deprivation, and other cellular stressors, where it functions to suppress mTOR activity and promote adaptive survival responses. The prominent staining observed within renal tubules is consistent with the high metabolic activity of these cells and the importance of stress-response pathways in maintaining renal homeostasis. Heat-induced epitope retrieval was performed by steaming tissue sections in pH 6 citrate buffer for 20 minutes and allowing them to cool prior to staining. These results support the utility of REDD-1 Antibody for studies of hypoxia signaling, mTOR pathway regulation, cellular stress responses, and kidney biology.

REDD-1 Antibody Human Pancreas IHC. IHC staining of FFPE human pancreas tissue with REDD-1 antibody demonstrated moderate to strong cytoplasmic staining of pancreatic epithelial cells, with particularly prominent staining within islet cell populations. REDD-1, also known as DDIT4 (DNA Damage Inducible Transcript 4), is a stress-responsive regulator of mTOR signaling that is induced by hypoxia, oxidative stress, nutrient deprivation, and metabolic challenges. By suppressing mTOR activity, REDD-1 helps coordinate cellular adaptation and energy conservation under adverse conditions. The staining pattern observed is consistent with the high metabolic activity of pancreatic tissues and the importance of stress-response pathways in maintaining cellular homeostasis. Heat-induced epitope retrieval was performed by steaming tissue sections in pH 6 citrate buffer for 20 minutes and allowing them to cool prior to staining. These results support the utility of REDD-1 Antibody for studies of mTOR pathway regulation, cellular stress responses, metabolism, and pancreatic biology.

REDD-1 Antibody Human HeLa WB. Western blot analysis of REDD-1 expression was performed using anti-REDD-1 antibody in human HeLa cell lysate. REDD-1, also known as DDIT4 (DNA Damage Inducible Transcript 4), is a stress-responsive protein that functions as a negative regulator of mTOR signaling and is induced by hypoxia, oxidative stress, DNA damage, and nutrient deprivation. A specific immunoreactive band is detected at approximately 25 kDa, corresponding to the predicted molecular weight of REDD-1. Additional higher molecular weight bands may represent post-translationally modified forms, protein complexes, or reduced electrophoretic mobility frequently observed for stress-response proteins. Expression in HeLa cells is consistent with the established role of REDD-1 in regulating cellular adaptation to environmental and metabolic stress. These results support the utility of REDD-1 Antibody for studies of mTOR pathway regulation, hypoxia signaling, cellular stress responses, and cancer biology.
