WebbThe pH buffer range of pipes is 6.1-7.5, insoluble in water and soluble in NaOH solution. Different from buffers containing bis (2-hydroxyethyl) amino groups (such as bis Tris, bicine), pipes can not form stable complexes with most metal ions, so it is suitable for buffers containing metal ions. WebbDESCRIPTION. Pipes and FIFOs (also known as named pipes) provide a unidirectional interprocess communication channel. A pipe has a read end and a write end. Data written to the write end of a pipe can be read from the read end of the pipe. A pipe is created using pipe (2), which creates a new pipe and returns two file descriptors, one referring ...
WebbGood set forth several criteria for such buffers: A pKa between 6 and 8. Most biochemical experiments have an optimal pH in the range of 6–8. The optimal buffering range for a buffer is the dissociation constant of the weak acid component of the buffer (pK a) plus or minus pH unit. Solubility in water. WebbPIPES is a buffering agent used in biochemistry and molecular biology that was selected and described by Good et al. It is a zwitterionic, piperazinic buffer that is useful for a pH range of 6.1 – 7.5. PIPES lacks the ability to form a significant complex with most metal ions and is recommended for use as a non-coordinating buffer in ...
