一般描述

凝集素是碳水化合物结合蛋白。它们无处不在,常见于真菌、植物和动物体内。该蛋白质的二级结构富含β-链,并且在表面上具有碳水化合物结合位点。[1]

应用

Triticum vulgaris(小麦)来源凝集素已用于:
  • 处理转染细胞,以进行免疫荧光分析[2]
  • 立体定位注射到小鼠体内,以进行神经元示踪[3]
  • 免疫组化,以分析心肌细胞[4]

用于荧光检测含有 β(1→4)-N-乙酰基-D葡糖胺的糖蛋白

生化/生理作用

WGA 不具有血型特异性,但具有与 N-乙酰基-β-D-葡糖胺残基和 N-乙酰基-β-D-葡糖胺低聚物的亲和性。WGA 不含蛋白结合糖。
凝集素在糖缀合物鉴定、成像和靶向过程中发挥着关键作用。它可用于芯片分析,实现有效的糖组图谱分析。在植物和真菌体内,凝集素可防御病原体/寄生物。凝集素在宿主识别和组织粘附中同样发挥主要作用。[1]

  2. Does Sigma provide a stain to visualize cell borders for human Cardiomyocytes derived from the GM23338 iPSC cell line?

    1 answer
    1. There is no recommended stain for cells from this type of cell line. However, for visualizing typical cardiomyocyte cell borders, one may consider L4895, as referenced by Vanhoutte D et al, Nat Commun. 2021 Jun 24;12(1):3928. L4895 is Sigma-Aldrich Lectin from Triticum vulgaris (wheat). The article titled "Thbs1 induces lethal cardiac atrophy through PERK-ATF4 regulated autophagy" in Nat Commun. 2021 Jun 24;12(1):3928 may serve as a point of reference.
