Transcriptomics Service

BioVenic provides tailored, high-precision transcriptomics analysis services for various aquatic species to uncover dynamic molecular regulatory mechanisms and advance both fundamental aquatic research and aquaculture industrial innovation. The transcriptome covers all RNA transcripts generated under specific spatiotemporal and environmental conditions, accurately mirroring real-time gene expression and cellular regulatory status. Distinct from fixed genomic data, transcriptomic profiling exposes ongoing biological activities such as aquatic growth, immune response and environmental adaptation.

Ideal Projects We Support

Common Challenges We Help Address

• Short-read sequencing limitations leading to incomplete transcript splicing information and inaccurate full-length gene structure annotation in non-model aquatic species.
• Unstable gene expression profiling caused by species-specific tissue characteristics and variable experimental conditions.
• Insufficient mining of non-coding RNA and interspecies interactive transcriptomic information in conventional sequencing analysis.
• Disconnection between differential gene expression data and phenotypic traits, restricting mechanism verification and marker development.

Core Aquatic Transcriptomics Services

• Full-Length Transcriptome Sequencing

Applicable Scenarios: Ideal for non-model aquatic species with imperfect reference genomes. It is widely used for complete transcript structure annotation, alternative splicing identification, new transcript discovery, and accurate gene isoform analysis, solving incomplete transcript information caused by traditional short-read sequencing.

Technical Capabilities: We deploy long-read sequencing technology to capture complete full-length mRNA sequences without splicing assembly. The optimized pipeline accurately identifies variable splicing patterns, gene fusion events, and novel functional transcripts, achieving high-precision transcript structure characterization for aquatic organisms.

Deliverables: Full-length transcript sequence data, complete transcript structure annotation results, alternative splicing analysis reports, novel gene identification lists, and comprehensive isoform expression profiling data.

• Reference-Based Transcriptome Sequencing

Applicable Scenarios: Suitable for aquatic species with mature reference genomes, applied for quantitative analysis of gene expression differences under different developmental stages, tissue types, disease infection and environmental stress conditions.

Technical Capabilities: Based on high-throughput short-read sequencing technology, we complete accurate genome alignment and gene expression quantification. We systematically screen differentially expressed genes and conduct functional enrichment analysis to reveal core molecular pathways regulating aquatic biological traits.

Deliverables: High-quality transcriptome sequencing raw data, gene expression quantitative results, differential gene screening lists, GO and KEGG functional enrichment reports, and gene expression pattern clustering analysis charts.

• Interactive Transcriptome Analysis

Applicable Scenarios: Focused on exploring molecular interaction relationships between aquatic organisms and symbiotic microorganisms, parasitic pathogens, or interactive species, supporting aquatic symbiosis mechanism and pathogenic interaction research.

Technical Capabilities: We design dual-transcriptome sequencing schemes to capture expression information of interactive species simultaneously. Professional bioinformatics analysis clarifies the correlation of differential gene expression between interacting subjects and reveals interspecies molecular regulatory networks.

Deliverables: Dual-species transcriptome expression data, interspecies differential gene correlation analysis results, interactive molecular pathway annotation reports, and symbiosis or pathogenic interaction mechanism interpretation conclusions.

• Exosomal Non-Coding RNA Sequencing

Applicable Scenarios: Used for exploring intercellular communication mechanisms in aquatic organisms, screening functional non-coding RNA markers involved in growth regulation, immune response and disease occurrence, and providing new targets for aquatic trait research and disease early warning.

Technical Capabilities: We achieve efficient isolation and high-throughput sequencing of aquatic exosomal ncRNAs including miRNA, lncRNA and circRNA. We analyze ncRNA expression profiles and their target gene regulatory relationships to reveal intercellular signal transmission mechanisms.

Deliverables: Exosomal ncRNA sequencing data, differential ncRNA expression profiles, target gene prediction results, ncRNA-mRNA regulatory network maps, and functional mechanism analysis reports.

Published Data on Aquatic Transcriptomics

Peer-reviewed published studies confirm that precise tissue and cell isolation is essential for reliable transcriptomic analysis, as sample cross-contamination leads to misidentified cell populations and biased result interpretation. Published research shows that fluorescent reporter transgenic lines in zebrafish, paired with fluorescence-activated cell sorting, enable highly specific cell isolation without manual dissection of fragile tissues. These literature-validated approaches also support rapid functional validation of candidate genes. Drawing on these published research findings, BioVenic optimizes standardized transcriptomic workflows for diverse aquatic research projects.
