DNA labeling technology - Opentrons中国官网

DNA markers

A technology that simultaneously fragments DNA and labels it with adapter sequences, primarily used to efficiently prepare DNA libraries for next-generation sequencing (NGS). This process is critical for workflows such as DNA sequencing, targeted studies, metagenomics, and chromatin analysis such as ATAC-seq.

Which workflows require DNA labeling?

The main purpose of DNA labeling is to prepare DNA libraries quickly and efficiently for next-generation sequencing. This process simplifies library preparation, reduces the time and steps required, and enables more uniform coverage during sequencing. DNA markers are commonly used in a variety of workflows, such as:

DNA sequencing, especially NGS workflows.
Targeted sequencing studies of specific genomic regions of interest.
Metagenomic studies sequencing diverse biological communities.
Chromatin profiling studies such as ATAC-seq (Analysis of Transposase Accessible Chromatin Using Sequencing).

Best methods for DNA labeling

Nextera DNA library preparation: This commercial method, developed by Illumina, uses a specific transposase for labeling.

ATAC-seq: This method combines tagging with sequencing to assess chromatin accessibility.

Customized transposase systems: Some research groups have optimized transposase enzymes and protocols for specific applications or organisms.

Why is DNA labeling so difficult?

Enzyme sensitivity: Transposase is sensitive to various factors such as concentration, reaction time and temperature. Small deviations can lead to over- or under-marking.

Optimization: Achieving uniform fragmentation and uniform coverage during sequencing requires careful optimization of labeling conditions.

DNA Quality: The purity and integrity of your DNA sample affects labeling efficiency and results.

Key challenges in DNA labeling with manual pipetting

Reproducibility: Manual pipetting can cause variations in enzyme and DNA concentrations, leading to inconsistent results.

Contamination risk: Manual pipetting increases the risk of cross-contamination between samples.

Efficiency: Preparing multiple samples simultaneously consumes a lot of labor and time.

Advantages of automated DNA labeling compared to manual pipetting:

Consistency and repeatability: Automated systems provide consistent output and reduce human error.

Throughput: Automated systems can process multiple samples simultaneously, significantly reducing preparation time.

Reduce the risk of contamination: Reduce manual intervention and reduce the risk of cross-contamination.

Optimization: Automated systems can be programmed to test multiple conditions simultaneously to help optimize labeling conditions.
