Used in biomedical research to detect and quantify phosphorylated cAMP response element-binding protein (pCREB) in rat tissue or cell samples. This ELISA kit enables researchers to study intracellular signaling pathways linked to gene expression, neuronal activity, memory formation, and cellular responses to stimuli such as stress, growth factors, or neurotransmitters. It is commonly applied in neuroscience, endocrinology, and pharmacology studies to assess activation of the cAMP/PKA pathway and evaluate the effects of drugs or experimental treatments on transcription factor regulation in rat models.
