Bis-Tris Bicine EDTA buffer or Bis-Tris buffer (pH 7.2) contains Bis-Tris and Bicine, zwitterionic buffer components that form strong bonds with common metals. In combination with ethylenediaminetetraacetic acid (EDTA), a metal chelator, that binds divalent cations. This buffer is commonly used as a transfer buffer in western blot to transfer proteins from the gel to the membrane.
应用
Bis-Tris buffer may be used in western blot as a transfer buffer.
