Used in life science research to detect and quantify Smad1 protein levels in cell or tissue samples. Plays a key role in studying TGF-β signaling pathways, which regulate cell growth, differentiation, and apoptosis. Commonly applied in cancer research, developmental biology, and immunology to understand signal transduction mechanisms. Enables researchers to assess activation states of Smad1 through phosphorylation detection, supporting investigation into disease mechanisms and potential therapeutic targets. Suitable for use with various sample types including lysates from mammalian cells. Provides a reliable, sensitive, and high-throughput method for protein measurement in experimental studies.
