Introduction of RPs Abundance Analysis
RPs are fundamental components of the ribosome, the cellular machinery responsible for protein synthesis. Far from being static components, the abundance and post-translational modification of RPs can change dynamically in response to cellular signals, developmental stages, and disease states. These changes alter the ribosome's function, leading to a phenomenon known as "specialized ribosomes" that can preferentially translate specific subsets of mRNAs. Quantitative analysis of RPs abundance, often through mass spectrometry, is a powerful technique for understanding these nuanced changes and their biological implications, as supported by a growing body of literature in cell and molecular biology.
Progress Trajectory
-
Sample Preparation and Protein Extraction
Upon receipt, our expert team performs meticulous sample preparation. This involves the lysis of cells or homogenization of tissue to extract total protein, followed by protein quantification using a Bradford or BCA assay to ensure a consistent starting material. -
Ribosome Isolation and Enrichment
The core of our service, this step uses a multi-stage differential centrifugation protocol or affinity-based methods to isolate intact ribosomes from the crude protein extract. This enrichment process is crucial for obtaining a clean, high-purity RPs fraction, which is then verified for quality.
-
Enzymatic Digestion and Peptide Labeling
The isolated RPs are digested into peptides using a specific protease. For relative quantification, we can use label-free or labeled techniques such as TMT or iTRAQ, which allow for the multiplexing of multiple samples in a single mass spectrometry run.
-
Mass Spectrometry Data Acquisition
The prepared peptide samples are analyzed using a state-of-the-art high-resolution mass spectrometer. This step generates raw mass spectral data that identifies and quantifies the peptides originating from RPs.

FAQs
Q: How can RPs abundance analysis assist my research in disease mechanisms?
A: RPs abundance and modification can act as early indicators of cellular dysfunction. By quantifying these changes, you can uncover novel pathways involved in diseases like cancer and neurodegeneration, potentially identifying new therapeutic targets or diagnostic biomarkers. We provide the quantitative data, and you gain the insights.
Q: What types of samples are compatible with your service?
A: Our service is highly versatile and works with a wide range of biological samples, including cell lines, fresh/frozen tissue, patient biopsies, and even purified ribosomes. If you have a unique sample type, please reach out to us to discuss your project; we are often able to develop a custom solution for your needs.
Q: How does your service compare to traditional methods like Western blotting?
A: While Western blotting provides a snapshot of a single or a few proteins, our mass spectrometry-based service offers a comprehensive, unbiased view of the entire ribosomal proteome. This high-throughput approach allows you to identify and quantify hundreds of RPs simultaneously, providing a much richer dataset for your research.
Q: How can I ensure the integrity of my samples for analysis?
A: Proper sample handling is key to success. We recommend flash-freezing your samples in liquid nitrogen immediately after collection and storing them at -80°C. We also provide a detailed sample submission guide to ensure the best possible results. Our team is available to offer advice before you even start your experiment.
Q: How can the data from this service be integrated into a larger systems biology project?
A: The quantitative data on RPs abundance and PTMs can be seamlessly integrated with other "omics" datasets to build a holistic model of your biological system. Our bioinformaticians can help you with this integration to unlock a deeper understanding of cellular function.
