Used in immunological research to detect and quantify mouse Flt3 (FMS-like tyrosine kinase 3) protein levels in biological samples such as serum, plasma, or cell culture supernatants. This kit is particularly valuable in studies related to hematopoiesis, immune system development, and leukemia research, as Flt3 plays a critical role in the proliferation and differentiation of hematopoietic stem and progenitor cells. Researchers use this assay to evaluate Flt3 expression under experimental conditions, assess the impact of therapeutic agents on Flt3 signaling, and investigate its involvement in cancer progression and immune disorders. The ELISA format allows for high sensitivity and specificity, making it suitable for preclinical studies and biomarker validation in mouse models.
