What Can We Do?
Our key capabilities include the isolation of total ribosomes (70S/80S), ribosomal subunits (30S, 50S, 40S, 60S), polysomes, and specific ribosome populations. We empower your research by providing the essential starting material for ribosome profiling, structural analysis, in vitro translation assays, and the identification of ribosome-associated factors. Our process is meticulously designed for efficiency and to ensure the highest quality ribosome preparations, suitable for a variety of downstream applications.
Starting Materials
- Cell Pellets or Tissue Samples
Sufficient quantity of cryopreserved cells (1x10⁸ mammalian cells) from your specific model system.
- Project Goals & Sample Information
A detailed description of your research objectives, the specific type of ribosomes needed (e.g., total ribosomes, polysomes, specific subunits), and any known characteristics of your samples.
- Buffer Preferences
If you have specific buffer requirements for your downstream applications, please provide the formulations. Otherwise, we will use our optimized, validated protocols.
Our Streamlined Workflow
-
Initial Consultation & Project Design
We commence with an in-depth exploration of your project requirements, the types of samples involved, and the desired outcomes you aim to achieve, all with the purpose of customizing the separation strategy. -
Sample Preparation & Lysis
Gentle and efficient cell or tissue lysis under conditions that preserve ribosome integrity and activity. This step is critical for preventing RNase degradation and dissociation of ribosomal complexes.
-
Ribosome Isolation & Crude Fractionation
Application of initial separation techniques, often involving differential centrifugation or sucrose cushion centrifugation, to enrich ribosomes and remove cellular debris and soluble proteins.
-
High-Resolution Separation/Purification
Utilization of advanced techniques such as sucrose density gradient centrifugation for separating ribosomal subunits, monosomes, and polysomes, or specialized affinity purification methods for isolating specific ribosome populations.
-
Quality Control & CharacterizationRigorous quality assessment including UV spectrophotometry (A260/A280 ratios), RNA integrity analysis, and optionally, protein analysis.
Case Study
- Sample Preparation
This case study details the procedure for preparing HeLa cells and subsequently isolating and purifying ribosomes, divided into sample preparation and ribosome purification stages.
Cells were cultured, and upon reaching confluence, cells were harvested. After low-speed centrifugation, cells were washed twice with PBS, transferred to cryotubes, centrifuged to remove residual liquid, snap-frozen in liquid nitrogen, and stored at -80°C.
- Ribosome Purification
Ribosome purification is initiated with ice-cold lysis buffer. The lysates were clarified through centrifugation, following which the supernatants were carefully layered onto sucrose cushions and subjected to ultra-centrifugation to isolate crude ribosomes. Following resuspension, samples underwent pretreated sucrose gradient centrifugation to separate ribosomal fractions. 80S ribosomes were collected, PEG-precipitated, and stored in a resuspension buffer at -80°C.

Applications
The high-quality ribosome preparations obtained through our specialized services are instrumental for a wide array of cutting-edge research applications. These include:
- Ribosome Profiling (Ribo-Seq)
Isolated ribosomes, particularly polysome fractions or affinity-purified translating ribosomes, are the essential input for Ribo-Seq. This powerful technique allows for genome-wide assessment of protein synthesis by sequencing ribosome-protected mRNA fragments, providing insights into translational control, identifying novel translated regions, and quantifying gene expression at the translational level.
- Structural Biology Studies
Highly purified and homogenous preparations of ribosomes and their subunits are critical for determining their three-dimensional structures. These structural insights are fundamental for understanding the mechanics of protein synthesis and for rational drug design targeting the ribosome.
- Drug Discovery
Bacterial ribosomes are a major target for antibiotics. Purified prokaryotic ribosomes and their subunits are used in high-throughput screening assays to identify novel antimicrobial compounds that inhibit bacterial protein synthesis.
- Analysis of Ribosome Modifications
Advanced separation techniques can help isolate specific subpopulations of ribosomes that may differ in their rRNA modifications, protein composition, or functional state.
