Product Overview
Dextran 70, with a molecular weight range of 64000-76000, is a highly purified, branched polysaccharide derived from Leuconostoc mesenteroides. This molecular biology grade reagent is an indispensable component in various laboratory applications, particularly where precise control over osmotic pressure and macromolecular behavior is crucial. Its unique characteristics, including high solubility in aqueous solutions and a relatively inert nature, make it an excellent choice for sensitive biological experiments. Dextran 70 is widely recognized for its consistent quality and reliability, ensuring reproducible results in demanding research environments.
As a neutral polysaccharide, Dextran 70 serves multiple critical functions. It is frequently employed as an osmotic agent to maintain cellular integrity and viability during cell culture and cryopreservation protocols. Its controlled molecular weight distribution allows for precise manipulation of solution viscosity and colligative properties. Furthermore, Dextran 70 is invaluable in size-exclusion chromatography, acting as a standard or a matrix component for separating proteins and other biomolecules based on size. Researchers rely on its consistent performance for applications ranging from protein stabilization to microencapsulation studies, where its biocompatibility and non-toxic profile are highly advantageous. Our Dextran 70 is rigorously tested to meet stringent purity standards, ensuring minimal contaminants that could interfere with experimental outcomes. It provides the foundational quality necessary for advancements in biological and biomedical research, enabling scientists and students across India to achieve their investigative goals with confidence and precision.
