一般說明
The 16S ribosomal RNA gene (16S rRNA) is a common bacterial marker, used as a target for microbial community profiling in microbiome metagenomic studies. The gene is composed of nine variable regions (V1-V9) interspersed between conserved regions. The most common 16S rRNA NGS assays target one or two regions using a single set of primers (e.g., V3-V4). However, this approach usually results in a poor bacterial detection and classification rate when the DNA input is of low-quality or when applying it on extremely low biomass samples. The 5R-PLEX kit offers a complete solution to challenging biological samples where the standard 16S sequencing protocols fail to perform. Sample types include:
- Formalin-Fixed, Paraffin-Embedded (FFPE) tissue
- Cancerous tumor tissue
- Degraded or damaged DNA
- Low biomass samples
- Fossil-derived and ancient DNA
特點和優勢
- The 5R-PLEX Kit provides high profile sequencing from degraded, damaged or low biomass samples
- Multiplexed NGS assay targets 5 variable regions of the 16S rRNA gene in a single primer pool
- Includes positive control for trouble shooting experiments.
- The kit can detect as low as 1pg of highly degraded bacterial DNA with an average fragment size of 260bp.
- Kit includes low bioburden reagents
- Includes exclusive access to M-CAMP™ platform featuring an innovative algorithm designed to reconstruct a single coherent microbial profiling and perform comprehensive analysis.

The accuracy of microbial community surveys based on marker-gene and metagenomic sequencing (MGS) suffers from the presence of contaminants-DNA sequences not truly present in the sample. Contaminants come from various sources, including reagents. Appropriate laboratory practices can reduce contamination, but

Bacteria were first detected in human tumors more than 100 years ago, but the characterization of the tumor microbiome has remained challenging because of its low biomass. We undertook a comprehensive analysis of the tumor microbiome, studying 1526 tumors and
