Mouse CD3 T Cell Isolation Kit (Negative Selection) is designed for the isolation of untouched CD3 T cells from mouse splenocytes and lymph node cells This kit operates by removing non-T cells via a cocktail of biotin-conjugated antibodies followed by magnetic beads which bind and remove unwanted cells The untouched T cells are left for downstream applications It is commonly used in immunological research focusing on elucidating T cell function in vitro where it demonstrates high purity and viability often in the nanomolar to low micromolar activity range Applications include cellular assays flow cytometry and functional studies including cytokine production and proliferation assays It plays a crucial role in drug discovery and development enabling the screening of compounds that affect T cell activity Experimental concentrations typically depend on the specific research design allowing for flexibility in various experimental setups
