mRNA Sequencing

Nucleome Informatics is leading Transcriptome sequencing or RNA Sequencing (RNA-Seq) service provider in India. One of the most popular forms of transcriptome sequencing is mRNA-Seq, which targets all polyadenylated mRNA transcripts, or the coding portion of the transcriptome. The depth offered by next generation sequencing is leveraged to find new genes that were undetectable before due to their low level of expression. By the same token, the increased depth and reduced cost of sequencing means these projects can be used to profile gene expression while differentiating between isoforms of the same gene via paired-end reads.

 

Transcriptome sequencing with longer read length enables the identification of novel transcripts, alternative splicing and gene fusions, and scientists can identify biomarkers or key regulated genes, key functional genes related to different phenotypes, as well as key factors in temporal changes. RNA-Seq quantification with shorter read length can simultaneously measure the expression levels of many transcripts. It is widely used in disease research, drug response research, pharmacokinetics, and personalized healthcare research. We have published multiple publications using mRNA Seq application in high impact factor journals.

Small RNA Sequencing

Team Nucleome Informatics is very well regarded for its expertise in Small RNA sequencing and data analysis services in India. Small noncoding RNAs act in gene silencing and post-transcriptional regulation of gene expression. Small RNA sequencing (RNA-Seq) is a technique to isolate and sequence small RNA species, such as microRNAs (miRNAs). We frequently use Illumina sequencing technology for Small RNA-Seq to query thousands of small RNA and miRNA sequences with unprecedented sensitivity and dynamic range.

 

With small RNA-Seq you can discover novel miRNAs and other small noncoding RNAs, and examine the differential expression of all small RNAs in any sample. Using our services one of our clients has recently published a paper ‘Analysis of high iron rice lines reveals new miRNAs that target iron transporters in root’ in Journal of Experimental Botany where team Nucleome discovered 153 known and 41 novel miRNAs in roots of rice. You can use our service to characterize variations such as isomiRs with single-base resolution, as well as analyze any small RNA or miRNA without prior sequence or secondary structure information.

 

Advantage of Small RNA Sequencing at Nucleome:

 

Team Nucleome generates miRNA sequencing libraries directly from total RNA to understand the role of noncoding RNA. Our trained team of genomics and bioinformatics can help you to-

  • Understand how post-transcriptional regulation contributes to phenotype.
  • Identify novel biomarkers.
  • Capture the complete range of small RNA and miRNA species.

Whole Transcriptome Sequencing

Whole-transcriptome analysis with total RNA sequencing (RNA-Seq) detects coding plus multiple forms of noncoding RNA. Total RNA-Seq can accurately measure gene and transcript abundance, and identify known and novel features of the transcriptome. Total RNA-Seq provides optimal coverage in normal or low-quality samples. Species-specific ribosomal RNA probes (Ribo-Zero chemistry) can efficiently remove abundant RNA species. This leaves both fragmented and intact transcripts of interest for library capture.

 

We can also use this approach to capture long non coding RNA sequence (lncRNA Seq). Long non-coding RNAs (LncRNAs) are transcribed RNAs longer than 200 nt that do not encode for proteins. LncRNAs are involved in a wide range of important cellular processes such as X-chromosome inactivation, imprinting, maintenance of pluripotency, lineage commitment and apoptosis. LncRNAs are also known to be involved with human diseases such as cancer, cardiovascular disease and neurological disorders, and are of significant interest to researchers.

 

Nucleome bioinformatics team offers comprehensive analysis for both lncRNAs and mRNAs, enabling access to lncRNA and mRNA information in a single sequencing run. Applications include comparison of lncRNA and mRNA expressions in different stages of development and in different tissues, as well as unveiling key functions of mRNAs and lncRNAs.

Single Cell RNA Sequencing

Single-cell sequencing is now readily available in India to researchers through Nucleome’s expertise in this field. Nucleome is one of the few NGS providers with extensive experience in single cell sequencing technology, including single-cell RNA-Seq. With ultra-low-input and single-cell RNA-Seq, you can explore the distinct biology of individual cells within a complex tissue, and understand subpopulation responses to environmental cues. These assays enhance the study of cell function and heterogeneity in time-dependent processes such as differentiation, proliferation, and tumorigenesis.

 

Single-cell RNA-Seq enables the high-resolution transcriptome profiling of a single cell, and has broad utility for investigating developmental processes and gene regulatory networks, and for revealing heterogeneous gene expression patterns within cell cultures, tissues, and organs.

circularRNA Sequencing

Nucleome Informatics is a leading service provider of circular RNA Sequencing in India. The circRNA digitalization analysis based on HiSeq high-throughput sequencing uses the SBS-sequencing by synthesis, which can decrease the loss of nucleotides caused by the secondary structure. It is also powerful for its small requirement of sample quantity, high through-put, high accuracy with easily operated automatic platform.

 Sample requirement

  • Total RNA amount: ≥ 2.0 μg; RNA concentration: ≥ 50 ng/μl (For human and mouse, 200 ng could be accepted with risk.)

DrSeq GEScore Biostimulants Testing

Biostimulants:

Biostimulants are a wide range of natural or synthetic products containing substances and microorganisms that can stimulate plant processes to improve nutrient uptake, nutrient efficiency, tolerance to abiotic stress, and crop quality.

(http:// www.biostimulants.eu/, accessed September 27, 2017)

The use of biostimulants is proposed as an advanced solution to face the demand for sustainable agriculture by ensuring optimal crop performances and better resilience to environmental changes. While the utility of some biostimulants has been proven scientifically, many growers remain sceptical of the agronomic claims.

DrSeq GEScoreTM service:

The Nucleome Informatics has developed a sequencing and data analysis approach to predict and characterise the function of natural compounds as biostimulants on plant system using DrSeq tool and BigData Decoder technology.  We are the leading company offering Biostimulant testing in India based on DrSeq GEScoreTM service.

Benefits:

By using DrSeq GEScoreTM service available at Nucleome Informatics, scientists can combine plant growth assessments and transcriptomic approaches to investigate and understand the specific mode(s) of action of BIOSTIMULANTS.  By using this technology, organisations manufacturing  Biostimulants can decipher the scientific background how the product stimulates the growth of the plant and reduces the plant’s biotic and abiotic stress. The company can also study the change in gene expression of the plants due to a variable dose of Biostimulants or change in treatment, duration, application, location, weather, germplasm etc. This study will help the R&D teams not only in novel product development but improving the older products too.

Deliverables:

We will provide the accession number of the data submitted in NCBI and DrSeq GEScoreTM based on exact scientific parameters of the Biostimulant testing with project report which can be used to publish these results as a research paper too.
