In the intricate world of cell culture, maintaining a stable and supportive environment is critical for experimental success. NINGBO INNO PHARMCHEM CO.,LTD. is proud to offer Poly-D-Lysine Hydrobromide (CAS 27964-99-4), a premium synthetic polyamino acid that addresses a common challenge in cell culture: the enzymatic degradation of Poly-L-lysine. For researchers working with cell lines that possess high cellular uptake mechanisms or enzymatic activity that can break down L-lysine polymers, our Poly-D-Lysine Hydrobromide provides a stable and reliable alternative, ensuring consistent cell adhesion and viability.

The unique advantage of Poly-D-Lysine Hydrobromide lies in its composition of D-amino acids. This chirality difference renders it largely resistant to the proteolytic enzymes that readily degrade their L-amino acid counterparts. This characteristic is particularly important for applications requiring long-term cell culture, where the integrity of the cell adhesion substrate is crucial. By preventing the breakdown of the coating, Poly-D-Lysine Hydrobromide ensures that the cells remain securely attached to the culture surface throughout the experimental period. This feature makes it an indispensable tool for studies involving sensitive cell types or protocols that demand extended observation times, contributing to more robust and reproducible results. The use of a stable cell culture medium is enhanced by such materials.

As a leading supplier in China, NINGBO INNO PHARMCHEM CO.,LTD. understands the nuances of biological research. We recognize that certain cell lines, when exposed to Poly-L-lysine, can lead to an excessive uptake of L-lysine, disrupting the cellular homeostasis and potentially affecting experimental outcomes. Poly-D-Lysine Hydrobromide circumvents this issue, providing a stable cell culture substratum that promotes cell attachment through electrostatic interactions without introducing the problematic L-lysine. This makes it an ideal choice for a wide range of applications, including the cultivation of primary cells, stem cells, and neuronal cells, where maintaining a consistent cellular environment is paramount. The ability to achieve consistent cell attachment enhancement is a key benefit.

Our commitment at NINGBO INNO PHARMCHEM CO.,LTD. is to provide high-purity, high-quality biomaterials. Poly-D-Lysine Hydrobromide is manufactured and tested to ensure it meets stringent specifications, making it a trusted reagent for researchers worldwide. Whether you are optimizing cell growth, developing new biomaterials, or exploring novel therapeutic strategies, our Poly-D-Lysine Hydrobromide offers the stability and performance you need to succeed. We aim to be your preferred supplier for essential synthetic polyamino acid products.
