They play an irreplaceable role in defending against extracellular pathogen infections and maintaining immune homeostasis. The CD19 molecule is the most representative lineage-specific marker on the surface of mouse B cells; it belongs to the immunoglobulin superfamily and is stably expressed from the early pre-B cell stage through the mature plasma cell stage. CD19 forms a signal-transduction complex with molecules such as CD21 and CD81, working synergistically with the B cell receptor (BCR) to lower the activation threshold of B cells and amplify downstream signaling cascades. As an important regulatory molecule in B cell development, activation, and differentiation, CD19 is widely used as a specific surface antigen for pan‑B cells in mice. In immunological research, obtaining highly purified, high‑activity pan‑B cells is a prerequisite for conducting functional analyses and studying signaling pathways. This negative selection kit is based on the principle of negative sorting: a biotin‑labeled antibody cocktail (excluding anti‑CD19 antibodies) specifically labels non‑B cells (such as T cells, NK cells, macrophages, and granulocytes), which are then efficiently removed using streptavidin‑coated nanomagnetic beads. Throughout the process, no antigens on the B cell surface are contacted, thereby maximizing the preservation of the cells' native morphology, the integrity of surface markers, and their physiological functional activity, providing high‑quality cellular material for downstream experiments.\u003c\/span\u003e\u003c\/p\u003e\u003c\/div\u003e\u003ch4\u003eProtocol\u003c\/h4\u003e\u003cdiv\u003e\n\u003cspan style=\"display:inline; white-space:nowrap;\"\u003eNote: This kit does not include sorting buffer; please prepare it yourself.
