Isolation of ribosomal particles is critical for studying ribosomal composition and for analyzing factors that interact with ribosomes. As a reputable global service provider, Creative Biolabs has extensive experience in ribosome extraction and isolation experiments. We provide cost-effective services according to the different needs of customers.
The ribosome is an important intracellular organelle, which is the molecular machine for intracellular protein synthesis. Ribosomes have no membrane structure and are mainly composed of RNA and proteins. Ribosomes are divided into two categories according to the sedimentation coefficient, one type (the 70S) exists in prokaryotes such as bacteria, and the other type (80S) exists in the cytoplasm of eukaryotic cells. Ribosome extraction refers to the isolation of ribosomes from specific cells or tissues. The prepared ribosomes can be used for the research of ribosome components, ribosome-interacting factors, ribosome-related diseases, and ribosome-related omics.
Strategies for isolating ribosomes vary for different organisms and experimental goals. In general, ribosome isolation mainly involves two strategies: centrifugation and immunoprecipitation (IP), both of which have advantages and disadvantages. Centrifugation techniques require long and multiple spins, thus exposing ribosomes to ribonucleases and proteases for extended periods. Another limitation is the poor solubility of the resulting ribosomal particles. In contrast, the IP method is fast and produces soluble ribosome yields. However, it requires adding tags to surface-exposed proteins, which can interfere with the study of the target. In addition, IP methods may lead to undesirable stripping of ribosomal cofactors, affecting study performance.
