Maintaining the integrity and stability of biological samples is fundamental to the success of research and diagnostic procedures. Bis-Tris, a high-performance biological buffer with CAS number 6976-37-0, plays a pivotal role in achieving these objectives. NINGBO INNO PHARMCHEM CO.,LTD., a reputable chemical supplier in China, provides Bis-Tris of exceptional purity, ensuring its efficacy across a spectrum of critical applications. This article highlights the crucial functions of Bis-Tris in ensuring sample integrity, particularly through freeze-drying, its contribution to the accuracy of creatine kinase assays, and its application in electrophoresis techniques.

A key application demonstrating Bis-Tris's ability to ensure sample integrity is its use in freeze-drying. This process, essential for preserving sensitive biomolecules like hemoglobin, often exposes these substances to harsh conditions. Bis-Tris acts as a vital protective agent, shielding molecules such as hemoglobin from denaturation and aggregation during the dehydration process. By maintaining a stable environment and interacting favorably with proteins, Bis-Tris helps preserve their functional structure and activity. This capacity to protect hemoglobin in freeze-drying makes it an indispensable reagent for the preparation of stable biological products and diagnostic kits. Ensuring the longevity and usability of biological materials is a core benefit provided by Bis-Tris.

Bis-Tris is also instrumental in enhancing the accuracy of biochemical assays, most notably in the detection of creatine kinase (CK). Creatine kinase is a crucial enzyme marker for muscle damage, and its precise measurement is vital for various diagnostic purposes. The accuracy of CK assays is heavily dependent on stable pH conditions, which Bis-Tris reliably provides. By buffering the reaction medium, Bis-Tris prevents pH fluctuations that could otherwise lead to inaccurate enzyme activity readings. This consistent buffering capability directly improves the sensitivity and reliability of creatine kinase detection, making Bis-Tris a preferred reagent for diagnostic laboratories. The need for biological buffers for enzyme detection with such dependable performance is constant in the field.

In advanced biochemical analyses, particularly in electrophoresis, Bis-Tris serves a critical function. It is commonly employed as a catholyte in Isoelectric Focusing (IEF) and is also utilized in 2-D gel electrophoresis. These techniques rely on stable pH gradients for the effective separation of proteins based on their isoelectric points. Bis-Tris contributes to establishing and maintaining these precise conditions, facilitating high-resolution protein analysis. Its role as a catholyte for IEF is indispensable for detailed proteomic studies, requiring a 99% assay biological buffer to ensure reproducibility and accuracy.
