Background	Tumor necrosis factor receptor superfamily member 9(TNFRSF9) is an inducible T cell surface protein belonging to the TNF receptor superfamily. It is a single-pass type I membrane protein which contains 4 TNFR-Cys repeats. The human and mouse proteins share 60% amino acid sequence identity. It is absent from naive T cells, but upregulated and continually expressed following T cell activation. It is a receptor for TNFSF9/4-1BBL, and possibly active during T cell activation.
Endotoxin	<1.0 EU/ug determined by the LAL method
Product Declaration	该产品仅供科研使用，不可直接用于人体或注射。

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。
