Used in biomedical research to quantify Rac1 protein levels in cell or tissue samples. Helps study cell signaling pathways involved in cytoskeletal reorganization, cell migration, and proliferation. Commonly applied in cancer research to investigate tumor cell invasion and metastasis mechanisms. Also utilized in neuroscience to examine neuronal growth cone dynamics and synaptic plasticity. Supports studies on inflammatory responses and immune cell function by measuring Rac1 activation in macrophages and neutrophils. Enables researchers to assess the impact of drugs or genetic modifications on Rac1 activity in various disease models.
