rRNA Subcellular Localization Service

Overview of rRNA Subcellular Localization

Ribosomal RNA (rRNA) serves as the fundamental building block for ribosome assembly and function, assuming a critical role in the process of protein synthesis. However, the spatial distribution of rRNA within cells, its subcellular localization remain a critical yet understudied aspect of cellular biology. rRNA subcellular localization dictates ribosome biogenesis pathways, stress responses, and even the specialization of ribosomes in distinct cellular compartments. Understanding where rRNA is synthesized, processed, and transported provides insights into cellular homeostasis, disease mechanisms, and therapeutic targets. At Creative Biolabs, we specialize in unraveling the subcellular journey of rRNA using cutting-edge technologies and interdisciplinary expertise. Our services empower researchers to map rRNA localization with unprecedented precision, enabling breakthroughs in fields ranging from cancer biology to neuroscience.

Advanced Technologies for rRNA Localization

1. Fluorescence In Situ Hybridization (FISH) with High-Specificity Probes

Our FISH workflows use custom-designed oligonucleotide probes (e.g., LNA-modified) targeting mature or precursor rRNA sequences. Combined with confocal or super-resolution microscopy, this technique reveals rRNA distribution in fixed cells/tissues, enabling studies of nucleolar organization, rRNA maturation gradients, and disease-associated mislocalization.

2. Live-Cell Imaging

By integrating split-GFP systems into rDNA, we visualize nascent rRNA transcripts as they emerge, process, and traffic within live cells. Utilizing advanced microscopy techniques, we can capture swift movements, thereby shedding light on the mechanisms underlying nucleolar export, polarized transport, and the relocalization of rRNA triggered by stress.

3. Subcellular Fractionation & High-Sensitivity Quantification

Using sucrose gradients, immunoisolation, or organelle enrichment, we isolate nucleolar, cytoplasmic, and organelle-specific rRNA fractions. Quantitative methods like ddPCR or RNA-Seq then measure rRNA levels, identifying compartment-specific isoforms and revealing ribosome heterogeneity in health and disease.

4. Computational Modeling & Bioinformatics Integration

Our bioinformatics pipelines integrate FISH, PLA, and fractionation data with single-cell RNA-seq or spatial transcriptomics. Machine learning algorithms predict rRNA trafficking pathways, while 3D modeling tools visualize subcellular distribution patterns, bridging the gap between experimental observations and biological interpretation.
