首先，表面張力測量證明牛精漿具有非常好的表面活性，這可能與 BSP 蛋白。 二、朗繆爾薄膜法 先前被證明是相關(guān)的脂質(zhì)單層模型 公牛精子的外細(xì)胞膜 [35]，有助于表征 BSP 蛋白對脂質(zhì)膜的親和力。 BSP 蛋白是 能夠到達(dá)被磷脂覆蓋的牛精子細(xì)胞表面，這要?dú)w功于它們與磷脂酰膽堿和 它們自身的表面活性。 我們的假設(shè)是，由于它們自己的表面，它們首先穿透精子的外葉 活動然后他們留在那里因?yàn)榕c 磷脂酰膽堿。 最后，Langmuir 薄膜法也得到了 用于篩選已知的 BSP 蛋白螯合劑（如 LDL 和脂質(zhì)體）的作用。 脂質(zhì)體被證明是 與 LDL 一樣有效地防止 BSP 蛋白插入 磷脂層。 發(fā)現(xiàn) LDL 和 脂質(zhì)體：0.16–0.17 mg 磷脂酰膽堿/mg BSP。 我們不 還知道脂質(zhì)體在 冷凍保存的時(shí)間尺度有一些生物學(xué)后果。 需要進(jìn)一步的研究來分析每個(gè)的表面特性 BSP 蛋白及其對膜的作用。 此外，可以測試?yán)士姞柋∧ひ詸z測 BSP 對膜的親和力隨溫度的變化 [20]。 最后，朗繆爾薄膜法是一種 用于鑒定新的螯合劑的強(qiáng)大篩選方法 BSP 蛋白質(zhì)。 這種方法可以適用于其他動物物種。
