What are mate pairs in sequencing?

Mate pair sequencing involves generating long-insert paired-end DNA libraries useful for a number of sequencing applications, including: De novo sequencing. Genome finishing. Structural variant detection. Identification of complex genomic rearrangements.

What is the difference between paired-end and mate pair?

Overview. To simplify, you can differ between two kinds of reads for paired-end sequencing: short‑insert paired‑end reads (SIPERs) and long-insert paired-end reads (LIPERs). The latter one is also called mate pair. The difference between the two variants is first – surprise – the length of the insert.

Does Illumina use paired-end sequencing?

All Illumina next-generation sequencing (NGS) systems are capable of paired-end sequencing.

What is the correct order of steps needed for Illumina sequencing?

Figure 3: Next-Generation Sequencing Chemistry Overview—Illumina NGS includes four steps: (A) library preparation, (B) cluster generation,(C) sequencing, and (D) alignment and data analysis.

Can you mix single end sequencing with mate pair sequencing?

Yes you combine them both.

Does Illumina sequence both strands?

Illumina gets sequence data from both strands of input sequence which means it outputs data from both ends of the input and is normally reported two files R1 and R2, often refereed to as mates files (R1=first mates, R2=second mates).

Why is paired-end sequencing better?

Paired-end reading improves the ability to identify the relative positions of various reads in the genome, making it much more effective than single-end reading in resolving structural rearrangements such as gene insertions, deletions, or inversions. It can also improve the assembly of repetitive regions.

How many base pairs can Illumina sequence?

Illumina offers a flexible range of paired read separation distances from 200 bp to 5 kb, enabling researchers to optimize each run to their specific goals. Standard paired- end libraries (200–500 bp) can be used to detect large and small insertions, deletions (indels), inversions, and other re arrangements.

What is the difference between a scaffold and a contig?

A scaffold is a portion of the genome sequence reconstructed from end-sequenced whole-genome shotgun clones. Scaffolds are composed of contigs and gaps. A contig is a contiguous length of genomic sequence in which the order of bases is known to a high confidence level.
