At CD Genomics, we are dedicated to providing you with groundbreaking insights into gene expression and translation regulation within cells. Our state-of-the-art technology allows you to delve deep into the world of polysomes, the dynamic complexes responsible for protein synthesis.

Overview of Polysome Profiling

The number of ribosomes bound to the mRNA reflects the translation efficiency of the gene and detecting mRNA translation efficiency is of great significance for the study of eukaryotic gene expression regulation. Polysome profiling takes advantage of the large sedimentation coefficient of ribosomes to separate polysomes by sucrose density gradient centrifugation. The more ribosomes bound to an mRNA, the faster the sedimentation rate during gradient centrifugation. Polysome profiling is increasingly used at the gene expression level of eukaryotes in life activities such as growth, disease, apoptosis, and tumorigenesis.

Our comprehensive Polysome Profiling Service covers the entire process, from experimental design to data analysis, enabling you to unravel the intricacies of cellular mechanisms with unprecedented precision.

Polysome Profiling vs. Ribo-Seq: Both are complementary techniques that can be chosen based on the research questions and goals. Polysome profiling provides insights into translation efficiency and regulation at a broader scale, while Ribo-Seq offers detailed information about ribosome positions and potential alternative translation events.

Project Workflow

Sample Requirements

When the sample is cultured to an appropriate time point, it is necessary to add cycloheximide (CHX, the final concentration is 100 μg/mL) to the medium for treatment. Store at -80°C after nitrogen quick freezing. (Please consult for specific experiments and sample types)

Experiment period: 11-13 weeks
