Technology

NGS – Sample Prep Technology

SeqOnce has developed a novel sample preparation approach which is faster and equivalent in quality to other products.
This proprietary technology incorporates a unique set of enzymatic reactions, which reduces reaction steps and reagents.

– Single tube preparation
– Input DNA as low as 500 pg, (lower input in R&D)
– DNA or cDNA (strand specific) preparation can be done with or without PCR (testing)
– Preparation time: with PCR – 30-40 min,  PCR free – 12-15 min (in R&D)
– Reduces preparation associated sequencing error

Nanoparticle Technology

SeqOnce has the ability to precisely synthetically control structure and composition of single- and mixed-metal nanoparticles [MMNPs]. This is key to tailoring their activity for specific roles in biomedical applications and material sciences and is, therefore essential in programming and optimizing their application-specific function.

SeqOnce has a wide range of custom nanoparticle synthesis, as well as bio-conjugates. We can provide nanoparticles from Nobel Metals, Transition Metals, Metalloids, Alkali Metals and Rare Earth metals as well as their stable and radio-isotopes.

SeqOnce can provide sterile nanoparticle suspensions and their affinity-targeted conjugates

NGS - Applications

Next Generation Sequencing (NGS) and Sample Preparation

Due to rapid progress and recent technological advances the cost of next generation sequencing has decreased dramatically over the past decade. However, the cost of sample preparation has not seen a concurrent cost reduction, with the result that sample preparation has been a limiting factor in the field. Fortunately, this is no longer the case and as a result of our revolutionary patented process we offer sample preparation (both DNA and RNA) at a fraction of the cost compared to other vendors. NGS applications include:

  • Whole-genome sequencing
  • Exome sequencing
  • Targeted sequencing
  • Total and mRNA sequencing
  • Methylation sequencing
  • ChIP-seq
  • Mitochondrial sequencing

DNA-seq (Whole Genome)

Whole-genome sequencing which allows for the entire genome of the organism to be determined enabling the identification of SNP's, indels and copy number variants. This information is necessary for further understanding the connection between mutations and different diseases. Mitochondrial sequencing is also commonly used to determine the mitochondrial genetic variation underlying disease, to measure heteroplasmy, to facilitate taxonomic identification, as well as for population genetics applications.

RNA-seq

RNA-seq is a technique that utilizes next-generation sequencing to explore transcriptome profiling and gene expression by analyzing the presence and quantity of RNA. RNA seq allows for far more precise measurements than other current methods such as hybridization (e.g. microarrays) or Sanger sequencing. This method can be used to ascertain the abundance of total RNA, noncoding RNA as well as small RNA’s. RNA seq facilitates the ability to identify:

  • Splicing patterns (and other post-transcriptional modifications)
  • Gene expression profiles (as conditions and/or development changes
  • Start sites, 5’ and 3’ ends
  • Novel and/or rare transcripts

Targeted Sequencing

Targeted sequencing isolates specific regions of interest in the genome and allows for increased cost effectiveness as well as coverage depth. Common uses for this technique include SNP validation, characterization of splice variants and to allow for accurate sequencing across repeats.

Methyl-seq

Methyl-seq, or bisulfite sequencing, is a technique that can be utilized to determine DNA methylation patterns. DNA methylation is a mechanism that cells use to control gene expression and is thought to play a role in a number of cellular processes (e.g. genomic imprinting, chromosome stability and during embryonic development), and errors in methylation have been linked to diseases such as cancer, lupus, muscular dystrophy as well as a number of birth defects. The technique to determine these methylation patterns relies on the fact that DNA treated with sodium bisulfite will react differently depending on whether the cytosines are methylated or not, and these differences can be subsequently identified by sequencing.

ChIP-seq

ChIP-seq is a technique that combines Chromatin immunoprecipitation (ChIP) with next-generation sequencing in order to ascertain how gene expression is influenced by the interactions between DNA and its associated proteins. In this method the transcription factor, cofactor, replication-related factor, or other chromatin protein is enriched through immunoprecipitation (an antibody based technique) in conjunction with its associated DNA. The enriched DNA can then be identified by sequencing thereby enabling the binding site of the factor to be determined, as well as the genome wide identification of all the regulatory sites for the associated factor.

Exome Sequencing

Exome sequencing which sequences only the protein coding regions of the genome. This technique is very useful for the detection of genetic variation that is likely to cause disease without incurring the cost associated with sequencing the entire genome.
