Description | 1. PIPPS has a similar buffer capacity and pH range as the Tris-buffer, but will not complex metal ions, also making it ideally suited for extraction of metal-dependent proteins. 2. PIPPS is a Good’s buffer, used for alkyl phosphine detergent and extraction, it is used in biotechnology. 3. PIPPS with pH of 4.0is used as a biological buffering agent. |
