| Background | Lymphocyte-activation gene 3(LAG3), also known as CD223, is a type I transmembrane protein with four extracellular Ig-like domains, designated D1 to D4 and belongs to the immunoglobulin superfamily. The gene for LAG3 lies adjacent to the gene for CD4 on human chromosome 12p13.32 and shares approximately 20% identical to the CD4 gene. LAG3 is expressed on activated T cells, natural killer cells, B cells and plasmacytoid dendritic cells. LAG3 binds with high affinity to MHC class II molecules, and it interferes competitively with the binding of CD4 to MHC class II and thereby blocks the transduction of stimulatory signals mediated by this interaction. LAG3 negatively regulates cellular proliferation, activation, and homeostasis of T cells, and plays an important role in Treg suppressive function. LAG3 is the target of various drug development programs to develop new treatments for cancer and autoimmune disorders. The soluble form, sLAG-3, is being developed as a cancer drug. |

低速离心:12,000 rpm, 5分钟,去除不溶物。缓冲液置换:使用超滤离心管(如10 kDa截留分子量)浓缩。
可优化表达条件(如降低诱导温度、调整IPTG浓度)、使用促溶标签(如SUMO、GST)、共表达分子伴侣,或尝试不同宿主系统(如哺乳动物细胞或昆虫细胞)以提高可溶性蛋白产量。
