| Product Name | PIPES dipotassium salt biological buffer, CAS 108321-27-3, for protein chemistry |
| Catalog No. | ATR-B-YJL-0294 |
| Description | PIPES dipotassium salt, also referred to as PIPES-K2, is the dipotassium salt form of PIPES and is widely used as a buffering and pH-stabilizing agent in protein chemistry and biochemistry. It is supplied as a white crystalline powder that dissolves readily in water and provides an effective buffering range of pH 6.1-7.5. The buffer is highly stable and, unlike many other buffering agents, does not lose its buffering performance over time. It also functions as a chelating agent, binding metal ions to form stable complexes, and it does not affect enzyme activity, which makes it broadly applicable across the biological sciences. |
| Intended Use | Used as a buffer in biological and chemical experiments that require a stable pH between 6.1 and 7.5. It is also suitable for electrophoresis, DNA/RNA separation, protein crystallization, biocatalysis, and enzyme activity assays. As a versatile and highly stable buffer that does not react with enzymes or affect cell growth, it is a valuable component of life-science research. |
