General description

Bis-tris 甲烷，也称为 BIS-TRIS 或 BTM，是一种广泛应用于生物化学和生物研究的两性离子缓冲剂。它在 pH 值范围为 5.8 至 7.2 的水溶液中有效发挥作用，并且其解离常数变化最小。此外，它可以用作剧毒缓冲剂二甲胂酸盐的替代品，并且还因其与不同金属形成络合物的能力而受到认可。

Application

Bis-Tris已被使用：
  • 作为电泳缓冲液
  • 作为蛋白质印迹转移缓冲液的组分

Features and Benefits

  • 适用于生物和生化研究
  • 在 pH 5.8-7.2 (25 °C) 范围内有效缓冲，pKa 为 6.5 (25 °C)

Immunoprecipitation (IP) of endogenously expressed proteins is one of the most biologically relevant techniques to identify protein-protein interactions. We describe an adaptable IP protocol reliant on a specific antibody to the target protein. We detail a quantitative proteomics workflow for

The best-understood mechanisms for achieving antibody self/non-self discrimination discard self-reactive antibodies before they can be tested for binding microbial antigens, potentially creating holes in the repertoire. Here we provide evidence for a complementary mechanism: retaining autoantibodies in the repertoire displayed
