Rat V-Fos FBJ Murine Osteosarcoma Viral Oncogene Homolog (FOS) ELISA Kit

The FOS gene encodes the c-Fos nuclear phosphoprotein, a core component of the activator protein-1 (AP-1) transcription factor complex that regulates genes involved in cellular proliferation, differentiation, and survival. From Assay Genie, this kit is widely applied in studies of bone remodeling, neuronal activation, immediate-early gene response, and tumor biology, where quantifying c-Fos expression in rat models provides insight into key signaling pathways.

The microplate format accommodates rat tissue homogenates and cell lysates, with reagents refrigerated at 4°C until first use; reconstituted standards should be aliquoted to minimize freeze-thaw cycles. A 100 µL sample volume is loaded per well for the in vitro immunoassay, supporting reproducible measurement across experimental batches.
