Immunoprecipitation Ribosome Isolation Service
Are you currently grappling with challenges in pinpointing actively translated mRNAs, comprehending cell-specific translation across diverse conditions, or the necessity to unveil novel regulatory mechanisms at the ribosomal level? At Creative Biolabs, our immunoprecipitation ribosome isolation service helps you pinpoint actively translated mRNA profiles, elucidate translational control in specific cell types or conditions, and discover new therapeutic targets through advanced affinity purification techniques targeting ribosomal components, often coupled with next-generation sequencing.
What is Ribosome Immunoprecipitation (RIP)?
Ribosomes, the molecular machines of protein synthesis, are not passive translators of genetic code. They actively participate in regulating gene expression by selectively translating subsets of mRNAs under specific conditions, such as stress, differentiation, and disease. RIP leverages antibodies targeting ribosomal proteins or associated factors to isolate ribosome-mRNA complexes, allowing researchers to:
- Profile actively translated mRNAs under defined conditions.
- Identify translational dysregulation in cancer, neurodegeneration, or metabolic disorders.
- Study ribosome heterogeneity (e.g., specialized ribosomes in stem cells).
- Map RNA-binding protein (RBP)-ribosome interactions governing mRNA fate.

Principle
RIP relies on the specificity of antibody-antigen interactions. By immobilizing antibodies against ribosomal markers on magnetic beads or agarose resin, researchers can capture ribosome complexes from cellular lysates. This approach surpasses traditional methods (e.g., polysome profiling) by:
- Targeting specific ribosome populations (e.g., 80S monosomes vs. polysomes).
- Enabling co-immunoprecipitation of interacting proteins/RNAs.
- Preserving post-translational modifications on ribosomal proteins.
Simple Workflow
-
Personalized Consultation & Experimental Design
We start with a detailed discussion to align our protocol with your research goals. Together, we select optimal antibodies and define control experiments to ensure data relevance to your biological questions. -
Gentle Lysis & Ribosome Stabilization
Cells or tissues are lysed under conditions preserving ribosome-mRNA complexes. Specialized inhibitors and optional cross-linking agents prevent RNA degradation and stabilize interactions during extraction.
-
Targeted RIP
Using validated antibodies, we affinity-purify ribosome complexes from lysates. This step balances efficiency and specificity to capture only ribosome-associated material.
-
Stringent Purification
Captured complexes undergo rigorous washing to eliminate non-specific binders. Ribosome-mRNA complexes are then eluted while maintaining RNA integrity for downstream use.
-
High-Quality RNA Extraction
RNA is isolated from immunoprecipitated ribosomes, yielding ribosome-protected fragments or bound mRNAs. Purity is verified using spectrophotometry and bioanalyzer traces.
-
QC & Quantification
RNA yield and quality are evaluated using spectroscopic and electrophoretic methods to confirm compatibility with sequencing or qPCR.
-
NGS Library Prep
For translatome profiling, we generate sequencing libraries optimized for ribosome footprint analysis (Ribo-seq) or mRNA enrichment (TRAP-seq).
-
Bioinformatic Analysis & ReportingOur team processes raw data, aligns sequences, quantifies ribosome occupancy, and performs differential translation analysis. Results are delivered with visualization tools and custom insights.

FAQs
Q: What sample types are compatible with RIP?
A: We accept mammalian cells (adherent/suspension), tissue lysates, purified ribosome fractions, and even plant/yeast samples. Contact us for FFPE or single-cell compatibility.
Q: Do you offer RNA-seq integration?
A: Yes! Our services include:
- RNA extraction → library prep → sequencing.
- Bioinformatics: Differential expression, Ribo-seq cross-referencing, and custom analyses (e.g., alternative polyadenylation).
Q: Can I use my antibodies?
A: Absolutely! We validate customer-provided antibodies for RIP compatibility (e.g., titer, cross-reactivity).
Q: How does RIP compare to polysome profiling?
A: RIP offers superior specificity by targeting ribosomes via antibodies, whereas polysome profiling separates ribosomes by sedimentation velocity. RIP is ideal for:
- Isolating specific ribosome populations (e.g., 80S vs. polysomes).
- Studying ribosome-associated proteins/RNAs without sucrose gradients.
Q: What controls are essential for RIP experiments?
A: Key controls include:
- IgG Isotype: Assess non-specific binding.
- Input/Output Comparison: Quantify enrichment via qPCR or Western blot.
- RNase Treatment: Confirm RNA-dependence of interactions.
Q: Can RIP be combined with other techniques?
A: Absolutely! Our platform supports multi-omics integration to deepen mechanistic insights:
RIP-MS (Mass Spectrometry): Profile ribosome-associated proteins and uncover post-translational modifications (e.g., phosphorylation) that regulate translation.
