Non-Reference based mRNA Sequencing-Illumina
Features
● Capture of poly mRNA before library preparation
● Independent of any reference genome: based on de novo assembly of transcripts, generating a list of unigenes that are annotated with multiple databases (NR, Swiss-Prot, COG, KOG, eggNOG, Pfam, GO, KEGG)
● Comprehensive bioinformatic analysis of gene expression and transcript structure
Service Advantages
● Extensive Expertise: with a track record of processing over 200,000 samples at BMK, spanning diverse sample types such as cell cultures, tissues, and body fluids, our team brings a wealth of experience to every project. We've successfully closed over 10,000 mRNA-Seq projects in various research domains.
● Rigorous Quality Control: we implement core control points across all stages, from sample and library preparation to sequencing and bioinformatics. This meticulous monitoring ensures the delivery of consistently high-quality results.
● Comprehensive Annotation: we use multiple databases to functionally annotate the Differentially Expressed Genes (DEGs) and perform the corresponding enrichment analysis, providing insights on the cellular and molecular processes underlying the transcriptome response.
● Post-Sales Support: our commitment extends beyond project completion with a 3-month after-sale service period. During this time, we offer project follow-up, troubleshooting assistance, and Q&A sessions to address any queries related to the results.
