● Study design:
Pooled sample sequenced with PacBio to identify transcript isoforms
Separate samples (replicates and conditions to be tested) sequenced with NGS to quantify transcript expression
● PacBio sequencing in CCS mode, generating HiFi reads
● Sequencing of the full-length transcripts
● Analysis does not necessitate a reference genome; however, it may be employed
● Bioinformatic analysis includes not only expression at gene and isoform-level but also analysis of lncRNA, gene fusions, poly-adenylation, and gene structure
● High Accuracy: HiFi reads with accuracy >99.9% (Q30), comparable to NGS
● Alternative Splicing Analysis: Sequencing all transcripts enables isoform identification and characterization.
● Combination of PacBio and NGS Strengths: It enables quantification of expression at the isoform level, unveiling change that may be masked when analysing the whole gene expression
● Extensive Expertise: We have processed over 2300 samples, our team brings a wealth of experience to every project.
● 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.
