Typical Workflow
Our systematic approach ensures comprehensive and reliable identification of ribosome-interacting proteins, suitable for clear visualization and understanding.
-
Consultation and Experimental Design
We begin with a thorough discussion of your research goals to tailor the analytical strategy, including decisions on enrichment methods, quantitative approaches (e.g., label-free, SILAC, TMT), and depth of analysis. -
Sample Preparation & Ribosome/Complex Enrichment
Your provided materials undergo meticulous processing. This may involve cell lysis, subcellular fractionation to enrich for ribosomes (e.g., ultracentrifugation through sucrose gradients), affinity purification if targeting specific ribosomal complexes, or using a bait protein.
-
Interaction Capture & Protein Processing
Ribosome-interacting proteins are co-isolated with ribosomal components. Proteins are then denatured, reduced, alkylated, and enzymatically digested (typically with trypsin) into peptides suitable for mass spectrometry.
-
Advanced Mass Spectrometry (MS) Analysis
Complex peptide mixtures are efficiently separated using liquid chromatography (LC) and analyzed by high-resolution tandem MS. This allows for both identification and quantification of thousands of proteins.
-
Comprehensive Bioinformatic AnalysisSophisticated algorithms and databases are used to identify proteins from MS/MS spectra. Quantitative analysis determines relative protein abundance changes between samples/conditions. Further analysis can include PTM identification, functional enrichment analysis, and mapping of potential interaction networks.

FAQs
Q: What types of biological questions can ribosome-interacting protein analysis address?
A: This analysis is powerful for discovering novel proteins that regulate translation, understanding how cellular conditions alter ribosome function by changing its protein partners, identifying components of specialized ribosomes, and mapping ribosome assembly pathways. We'd be happy to discuss how it can specifically advance your research focus!
Q: How do you ensure the identification of genuine interactors versus non-specific binders?
A: We employ optimized protocols with stringent wash conditions, appropriate controls (e.g., isotype controls for Co-IP, or comparison with non-ribosomal fractions), and sophisticated bioinformatic filtering based on abundance, recurrence, and known localization data to significantly enhance the confidence in identified interactors.
Q: Can your service differentiate between proteins that stably associate with ribosomes and those that interact transiently?
A: Yes, by tailoring the experimental conditions, such as using cross-linking strategies for transient interactions or specific enrichment protocols for stable complexes, we can provide insights into the nature of these associations. Quantitative proteomics can also reveal dynamic shifts indicative of transient binding. Let's discuss the best strategy for your targets.
Q: What is the typical protein expression level required for an interacting protein to be identified by your service?
A: Our advanced MS platforms are highly sensitive and capable of detecting even low-abundance interactors. However, the success rate is also contingent upon the stoichiometry of the interaction and the efficiency of the enrichment process.
Q: How does Creative Biolabs's mass spectrometry-based analysis compare to traditional methods like yeast two-hybrid (Y2H) or Co-IP followed by Western blot for studying ribosome interactions?
A: While Y2H and Co-IP/Western blot are valuable for studying specific binary interactions, our MS-based approach offers a much broader, unbiased discovery platform, identifying hundreds to thousands of interactors simultaneously without prior knowledge. It also provides quantitative information about these interactions, offering a more comprehensive view of the ribosome interactome.
