  抗體純化 (Antibody Purification)

 Prosep-A/Prosep-G 抗體純化用樹指

 特性:
 •可純化單株(Monoclone)及多株(Polyclone)抗體,純化產量高及純化效率佳
 •非一般的Sephrose基質,為玻璃珠材質,可耐高壓,高流速且適合各種酸鹼值溶液,溶液耐受性高
 •亦可適用於immunoprecipitate實驗,分離效果佳,離心過程不容易碎裂
 •可搭配FPLC或僅用離心方式使用且重複使用次數高
 •另有試劑套組包含所有試劑,方便使用,60分鐘可做完抗體純化

 The capacity of PROSEP-A High Capacity for
 various polyclonal antibodies. Polyclonal antibodies
 were adsorbed from PBS pH 7.4 and eluted with
 0.1M glycine/HCl pH 3.5-2.2

 Maximum capacities of PROSEP-A High Capacity
 for various monoclonal antibodies and
 immunoglobulin fusion proteins. Capacities were
 determined using optimized conditions.
