一般描述

流感病毒血凝素(HA)前体基因编码在片段4上。它编码一个76kDa表面糖蛋白,该蛋白作为三聚体存在于病毒包膜上。

特异性

该抗体可识别HA-标签蛋白的天然和还原变性形式,并且可与 大肠杆菌 或哺乳动物表达的N-末端或C-末端HA-标签融合蛋白发生反应。

免疫原

与人流感病毒血凝素(HA)片段相对应的合成肽,称为HA-标签,与KLH结合

应用

小鼠抗 HA 单克隆抗体抗体可用于 293T 细胞,用于:
  • 人胚肾 293 细胞的免疫沉淀
  • HeLa 细胞免疫印迹
  • 人胚肾 293 细胞的免疫纯化
  • 小鼠胚胎成纤维细胞电子显微镜免疫染色
  • 海马切片的免疫细胞化学
小鼠抗 HA单克隆抗体可用于:
  • 免疫印迹,研究融合蛋白的表达
  • 免疫共沉淀试验
  • 裂解物蛋白的免疫印迹

生化/生理作用

流感病毒血凝素(HA)是禽流感病毒(AIV)疫苗的关键免疫原。活化的HA促进病毒附着在宿主细胞表面的寡糖受体上,并参与内溶酶体室构象改变后融合渗透。H3亚型血凝素(HA)中的226和228个残基在宿主范围限制和受体特异性方面发挥着关键作用。流感病毒血凝素(HA)是1918年流感大流行的罪魁祸首。
血凝素(HA)是流感病毒的表面糖蛋白。Ha是病毒进入宿主细胞表面并与 N-乙酰神经氨酸(Neu5Ac)相互作用的关键。HA与神经氨酸酶(NA)协作,促进病毒进入宿主。HA以三聚体的形式存在,每个单体都有茎跨膜和球状区域。球状区域含有对感染宿主至关重要的碳水化合物侧链。

储存及稳定性

若连续使用,可在2-8℃下保存长达一个月。
若长期保存,分装冷冻保存。不建议反复冻融或存放在“无霜”冰柜中。如果长期储存时出现轻微浑浊,请在使用前通过离心澄清溶液。工作稀释液如果在12个小时内未使用,则应丢弃。

  5. What is the isotype and light chain for Monoclonal Anti-HA antibody clone HA-7 produced in mouse?

    Monoclonal Anti-HA antibody clone HA-7 is mouse IgG1, kappa light chain.

  6. What is the recommended dilution of Product H9658 - HA antibody for immunoprecipitation and for indirect immunostaining?

    H9658 - Monoclonal Anti-HA antibody produced in mouse is the ascites fluid. It is not purified. We only test this product in western blotting.  This product contains 15-55 mg/ml total protein with 4-7 mg/ml specific antibody. H3663 - Monoclonal Anti-HA antibody produced in mouse as the purified immunoglobulin. We test this product for immunoprecipitation using 0.5-2.0 μg and for immunocytochemistry using 1.0-2.0 μg/mL.These ranges would be a good starting concentration. In order to obtain best results in different techniques and preparations, we recommend determining optimal working dilution by titration test.
