产品介绍
链霉亲和素（Streptavidin）是由相同亚基组成的四聚体蛋白。每个亚基可结合一个生物素分子，其结合常数（KD）约为1x10⁻¹⁵ M。本产品为N端和C端截短的链霉亲和素变体（核心链霉亲和素），与天然链霉亲和素相比，具有以下改进特性：
更高的均一性
更好的溶解性
更强的抗蛋白酶降解能力
生物素结合位点更易接近
链霉亲和素对生物素及其衍生物的高亲和力识别，使其成为诊断和实验室试剂盒中最重要的成分之一。

Product Description
Streptavidin is a tetrameric protein composed of identical subunits. Each subunit binds one biotin molecule with an extremely high affinity (KD ~1x10⁻¹⁵ M). This preparation contains a core streptavidin variant, which is an N- and C-terminal truncated form with improved properties, including:
Enhanced homogeneity
Increased solubility
Greater resistance to proteolytic degradation
Improved accessibility of the biotin-binding pocket
Compared to native streptavidin, the core streptavidin variant offers superior performance in various applications. The high-affinity binding of streptavidin to biotin and biotinylated molecules has made it a critical component in diagnostics and laboratory kits.
