Used in immunological research to quantify Rat Recombinant Activation Gene 1 (RAG-1) protein levels in biological samples such as serum, plasma, or tissue homogenates. This ELISA kit enables researchers to study V(D)J recombination processes, which are critical for the development of B and T lymphocytes. It is commonly applied in studies related to immune system development, autoimmune diseases, and immunodeficiency disorders in rat models. The assay provides a sensitive and specific method to monitor RAG-1 expression during immune responses or following experimental treatments involving immune modulation.
