Used in immunological research to detect and quantify FMS-like tyrosine kinase 3 (Flt3) protein levels in rat biological samples such as serum, plasma, or cell culture supernatants. This ELISA kit is particularly valuable in studies related to hematopoiesis, immune system regulation, and cancer research, especially in investigating acute myeloid leukemia (AML) and other hematological malignancies where Flt3 signaling plays a critical role. The assay enables researchers to monitor Flt3 expression changes in response to experimental treatments, assess disease progression, or evaluate the efficacy of targeted therapies in preclinical models. Its high sensitivity and specificity make it suitable for detailed biomarker analysis in rodent-based studies.
