Background	Fibrinogen-like protein 1(FGL1) is also known as HP-041, Hepassocin, HFREP-1, LFIRE-1, is a liver-specific secreted protein belonging to the fibronogen superfamily, whose members share a fibrinogen domain at their C-termini. It is secreted by the liver and functions as a mitogen for hepatocytes. Hepassocin may play a role in the development of hepatocellular carcinomas. Hepassocin is a disulfide-linked homodimeric protein with a C-terminal fibrinogen domain. It is reported that it is a major immune inhibitory ligand of LAG-3.

FAQ

如何提高重组蛋白的可溶性表达？

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。
重组蛋白纯化常用的方法有哪些？

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。
