Are you facing challenges in isolating and analyzing specific cellular components like ribosomes, viral particles, or intricate macromolecular complexes? Do you need to accurately assess translational activity or require highly purified samples for sensitive downstream applications? Our sucrose gradient centrifugation service helps you achieve high-resolution separation and robust analysis of these vital biological entities through meticulously optimized protocols, state-of-the-art technology, and expert execution, empowering your discoveries.
Sucrose gradient centrifugation is a highly versatile and powerful technique fundamental to molecular biology and biochemistry. It employs ultracentrifugation to separate macromolecules and cellular organelles, such as ribosomes, polysomes, viruses, proteins, and nucleic acids based on their sedimentation coefficients, which are determined by their size, shape, and density. By creating a density gradient with varying concentrations of sucrose, researchers can achieve fine resolution of complex biological mixtures. This method is invaluable for applications ranging from assessing cellular translational activity via polysome profiling to purifying viral particles and isolating specific macromolecular complexes for functional or structural studies.
Our workflow is designed for clarity, efficiency, and the highest quality outcomes. The key steps involved are as follows:
