| Background | Lymphocyte Activating 3(LAG3) belongs to immunoglobulin(Ig) superfamily, Macaca fascicularis LAG3 cDNA encodes 533 amino acids(aa) that include a 17 aa signal sequence, a 451 aa extracellular domain(ECD) with two Ig-like domains, a transmembrane region and a highly charged cytoplasmic region. LAG3's main ligand is MHC class II, to which it binds with higher affinity than CD4.The protein negatively regulates cellular proliferation, activation, and homeostasis of T cells, in a similar fashion to CTLA-4 and PD-1 and has been reported to play a role in Treg suppressive function. |

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。
常用的纯化方法包括亲和层析(如His-Tag、GST-Tag)、离子交换层析、疏水相互作用层析(HIC)和凝胶过滤层析。具体方法取决于蛋白特性和标签类型。
