At N2Jenomics Lab Pvt. Ltd., we offer comprehensive Plasmid and Bacteriophage (Phage) Sequencing solutions designed to deliver complete, high-resolution genomic insights. Leveraging advanced next-generation sequencing (NGS) technologies and robust bioinformatics workflows, we perform accurate de novo genome assembly, eliminating the dependence on reference genomes. This approach enables precise characterization of both plasmid and phage genomes, supporting research across microbiology, biotechnology, environmental science, and antimicrobial resistance.

What is Complete Phage/Plasmid Sequencing

Plasmids are small, circular DNA molecules that replicate independently of the bacterial chromosome. They frequently carry genes responsible for important biological functions, including antibiotic resistance, virulence, stress tolerance, and specialized metabolic pathways. Because plasmids can move between bacterial cells through horizontal gene transfer, they play a critical role in microbial adaptation and evolution.

Bacteriophages, commonly known as phages, are viruses that specifically infect bacteria. They influence bacterial population dynamics, facilitate gene exchange, and contribute significantly to microbial diversity and ecosystem balance. Phages are also increasingly being explored for therapeutic applications, biotechnology, and bacterial control strategies.

Complete plasmid and phage sequencing provides the full genetic blueprint of these mobile genetic elements. By decoding their entire genomes, researchers can identify structural features, functional genes, regulatory regions, and accessory genetic elements that influence bacterial behavior, pathogenicity, and adaptability. These insights are invaluable for studies involving antimicrobial resistance, microbial evolution, synthetic biology, industrial biotechnology, and environmental microbiology.

Our Plasmid & Phage Sequencing Approach

Plasmids and bacteriophages vary widely in genome size, sequence complexity, GC content, and repetitive regions. These characteristics often make conventional sequencing approaches challenging, resulting in incomplete assemblies or longer turnaround times.

At N2 JENOMICS, we combine state-of-the-art sequencing platforms with advanced computational analysis to overcome these challenges. Our integrated workflow enables:

•  

• • High-quality de novo genome assembly 

• • Accurate identification of plasmid and phage structures  

• • Detection of coding and non-coding genetic elements 

• • Characterization of antimicrobial resistance and virulence-associated genes 

• • Genome annotation and comparative genomic analysis 

• • Identification of structural variations and repetitive regions 

• • Publication-ready genomic datasets and comprehensive analytical reports 

Our optimized sequencing and bioinformatics pipelines ensure reliable, high-quality results, even for complex plasmid and phage genomes.

Phage Whole-Genome Sequencing

Comprehensive Phage Genomics Solutions

At N2Jenomics Lab Pvt. Ltd., we provide advanced Phage Whole-Genome Sequencing services designed to deliver complete genomic insights into bacteriophages. By integrating cutting-edge short-read (Illumina) and long-read sequencing technologies (PacBio HiFi and Oxford Nanopore), we generate highly accurate, complete phage genome assemblies suitable for research, clinical, environmental, and industrial applications.

Our comprehensive sequencing workflow supports both de novo genome assembly and reference-guided analysis, enabling accurate reconstruction of phage genomes regardless of genome complexity. Optimized laboratory protocols and advanced bioinformatics pipelines ensure reliable characterization of GC-rich regions, repetitive sequences, structural variants, and complex genomic architectures.

In addition to high-quality genome assemblies, we provide detailed functional annotation, genome visualization, comparative analysis, and biological interpretation to support downstream research and publication.
