J14 cells are a unique Jurkat-derived human T cell line that lacks expression of SLP-76 (SH2 domain–containing leukocyte protein of 76 kilodaltons), an adaptor protein and PTK substrate expressed in hematopoietic cells (2). SLP-76 together with the scaffolding protein LAT act as a hub for various signaling effectors (1). Except SLP-76, the expression profile of J14 cells encompasses all necessary components of downstream pathways including those required for IL-2 cytokine induction (3), making the J14 cell line ideal for mutational analysis and introduction of reporter constructs. Source:J14 cells are a clonal derivative of Jurkat, a T cell line derived from bone marrow of a 14-year old male (4). Jurkat cells were transfected with an episomal vector and selected for hygromycin resistance. The transgene was subsequently lost via non-selective growth (2).，官网链接：https://www.sigmaaldrich.cn/product/mm/scc190 默克 科研、开发、生产。 作为生命科学行业的全球领先供应商，我们致力于为科研、生物技术开发和生产，以及制药药物疗法开发和生产提供各类解决方案和服务。
