Radiolabeled pharmacological binding assay showed: 1 BmK AS bound specifically to a single class of non-interacting binding sites on both rat brain and cockroach nerve cord synaptosomes with high affinity and low low capacity. The association of BmK AS with both synaptosomes was quick to reach equilibrium, but the dissociation seemed to be only partial. The specific binding of BmK AS was independent of membrane potential, and couldn't be modified by veratridine. Moreover, the binding of BmK AS could be inhibited by native BmK AS, BmK AS1, BmK IT2 and BmK IT on both synaptosomes, but not or partially inhibited by BmK Ⅰ and suggesting BmK AS type neurotoxins might bind to a distinct receptor site on mammal and insect sodium channels with a similar manner from β-scorpion toxins.

二。蝎毒素多肽配体与哺乳动物和昆虫靶离子通道受体的药理结合特性及其靶结合位点的研究：经放射性标记结合和竞争抑制实验表明：1）BmK AS在大鼠脑和蟑螂神经索突触体上有单一非协同性高亲和力低结合容量结合位点，能快速结合并达到平衡，但仅能部分解离，其结合不依赖于膜电位，也不受藜芦碱调节，天然的BmK AS，BmK AS-1，BmK IT2和BmK IT可抑制〓AS与两种突触体的特异结合，而BmK Ⅰ无或仅有部分抑制效应。
