應用

来自荆豆(gorse, furze)的凝集素已被用于:
  • 免疫组化中作为的潘氏细胞标记物(稀释度为 1:1,000 )
  • 血管定量中内皮细胞双重染色
  • 支气管上皮细胞的组化染色

生化/生理作用

荆豆凝集素具有抗H血型特异性。凝集素有两种类型: UEA I 对 L-岩藻糖具有亲和力,而 UEA II 对 N,N′-二乙酰壳二糖具有亲和力。最初认为UEA I摩尔量为170,000道尔顿。 后来的报道表明,UEA I可以在中性和碱性pH下形成聚集体,正确的摩尔量是68,000道尔顿。

Glycoconjugates in the olfactory system play critical roles in neuronal formation, and α1-2 fucose (α1-2Fuc) glycan mediates neurite outgrowth and synaptic plasticity. Histochemical findings of α1-2Fuc glycan in the mouse olfactory system detected using Ulex europaeus agglutinin-I (UEA-I) vary. This
