MtoZ Biolabs utilizes advanced instruments and analytical platforms to offer the protein-RNA interaction analysis service which can be used to characterize protein-RNA binding features and interaction patterns. This service is suitable for research on post-transcriptional regulation and the functional analysis of RNA-binding proteins, providing reliable data support for understanding RNA-related regulatory processes.

What Is Protein-RNA Interaction?

Protein-RNA interaction refers to the binding relationship formed between proteins and RNA through specific structural domains or sequence recognition, serving as a fundamental basis for post-transcriptional regulation, RNA processing, and stability maintenance. RNA-binding proteins play essential roles in processes such as splicing, editing, transport, and translation, and changes in their binding patterns often directly affect gene expression. Analyzing these interactions helps identify key regulatory nodes and deepens the understanding of cellular functions and regulatory processes.

Protein-RNA Interaction Analysis Service at MtoZ Biolabs

1. RNA Immunoprecipitation (RIP/RIP-seq)

This method enriches specific RNA-binding proteins with antibodies and detects their associated RNAs. It can be used to verify naturally occurring protein-RNA interactions and, combined with sequencing, to obtain a global binding profile.

2. RNA Pull-Down

Using biotin-labeled RNA to capture proteins that bind to it, this method can directly identify interacting proteins and assess their binding specificity, and is suitable for in vitro validation and the discovery of new interactions.

3. Chromatin Isolation by RNA Purification (CHIRP)

Using specific probes to enrich target RNA and its binding complex, RNA-mediated binding networks and related components can be resolved under conditions closer to physiological conditions.

4. Crosslinking and Immunoprecipitation Sequencing (CLIP-seq)

By immobilizing protein-RNA complexes through ultraviolet crosslinking and performing immunoenrichment and sequencing, binding sites can be located at high resolution and direct interactions can be analyzed.

5. High-resolution Mass Spectrometry Analysis

High-resolution mass spectrometry can be used to identify interacting components in RNA pull-down or CHIRP-enriched samples and can quantify changes in interacting proteins under different conditions, supporting in-depth analysis of interaction characteristics.

FAQ

Q1: What kind of samples are suitable?

A1: Suitable samples include protein and RNA samples with a clear origin, high purity, and no significant degradation. These include recombinant proteins, endogenous proteins from cell or tissue lysates, in vitro transcribed RNA, and cell-extracted RNA. Samples should maintain good integrity to ensure authentic and reproducible interaction signals.

Q2: What is the service general workflow?

A2:

Q3: What data formats are provided?

A3: MtoZ Biolabs provides several standardized output types, including:

• Raw experimental data files (e.g., sequencing data, mass spectrometry raw files)
• Protein-RNA interaction analysis tables (Excel/CSV)
• Visualization charts (PNG/TIFF)
• Bioinformatics analysis results
• Comprehensive analysis report (PDF, including experimental methods, quality control, and result interpretation)

If special analytical requirements exist, data formats can be customized according to project specifications.

Q4: How should I prepare samples?

A4: To ensure optimal detection results, it is recommended to prepare samples in the following ways:

• Sample purity: Keep samples free of significant impurities or degradation, and avoid metal ions, high salt, strong detergents, etc., which can interfere with binding behavior.
• Sample Storage: Protein samples should be stored at 4℃ for short periods and -80℃ for long periods; RNA should be stored at low temperatures and protected from light, and freeze-thaw cycles should be avoided as much as possible.
• Sample Transportation: Use sealed containers and transport under dry ice or low-temperature conditions to prevent loss of activity or structural alteration.
• Additional Information: We provide sample source, concentration, sequence information, buffer system, and processing steps to facilitate the development of the most suitable experimental protocol.
