  • PacBio 2+3 Full-Length mRNA Solution

    PacBio 2+3 Full-Length mRNA Solution

    While NGS-based mRNA sequencing serves as a versatile tool for gene expression quantification, its reliance on short reads restricts its efficacy in complex transcriptomic analyses. PacBio sequencing (Iso-Seq), on the other hand, employs long-read technology, enabling the sequencing of full-length mRNA transcripts. This approach facilitates a comprehensive exploration of alternative splicing, gene fusions and poly-adenylation although it is not the primary choice for gene expression quantification. The 2+3 combination bridges the gap between Illumina and PacBio by relying on PacBio HiFi reads to identify the complete set of transcript isoforms and NGS sequencing for quantification of the same isoforms.

  • Genome-wide Association Analysis

    Genome-wide Association Analysis

    The aim of Genome-Wide Association Studies (GWAS) is to identify genetic variants (genotypes) linked to specific traits (phenotypes). By scrutinizing genetic markers across the entire genome in a large number of individuals, GWAS extrapolates genotype-phenotype associations through population-level statistical analyses. This methodology finds extensive applications in researching human diseases and exploring functional genes related to complex traits in animals or plants.

    At BMKGene, we offer two avenues for conducting GWAS on large populations: employing Whole-Genome Sequencing (WGS) or opting for a reduced representation genome sequencing method, the in-house-developed Specific-Locus Amplified Fragment (SLAF). While WGS suits smaller genomes, SLAF emerges as a cost-effective alternative for studying larger populations with longer genomes, effectively minimizing sequencing costs, while guaranteeing a high genetic marker discovery efficiency.

  • Single- nucleus RNA Sequencing

    Single- nucleus RNA Sequencing

    The development of single-cell capture and custom library construction techniques, coupled with high-throughput sequencing, has revolutionized gene expression studies at the cell level. This breakthrough allows for deeper and more comprehensive analysis of complex cell populations, overcoming the limitations associated with averaging gene expression over all cells and preserving the true heterogeneity within these populations. While single-cell RNA sequencing (scRNA-seq) has undeniable advantages, it encounters challenges in certain tissues where the creation of a single-cell suspension proves difficult and requires fresh samples. At BMKGene, we address this hurdle by offering single-nucleus RNA sequencing (snRNA-seq) using the state-of-the-art 10X Genomics Chromium technology. This approach broadens the spectrum of samples amenable to transcriptome analysis at the single-cell level.

    The isolation of nuclei is accomplished through the innovative 10X Genomics Chromium chip, featuring an eight-channel microfluidics system with double crossings. Within this system, gel beads incorporating barcodes, primers, enzymes, and a single nucleus are encapsulated in nanoliter-sized oil drops, forming Gel Bead-in-Emulsion (GEM). Following GEM formation, cell lysis and barcode release occur within each GEM. Subsequently, mRNA molecules undergo reverse transcription into cDNAs, incorporating 10X barcodes and Unique Molecular Identifiers (UMIs). These cDNAs are then subjected to standard sequencing library construction, facilitating a robust and comprehensive exploration of gene expression profiles at the single-cell level.

  • Plant/Animal Whole Genome Sequencing

    Plant/Animal Whole Genome Sequencing

    Whole Genome Sequencing (WGS), also known as re-sequencing, refers to the whole genome sequencing of different individuals of species with known reference genomes. On this basis, the genomic differences of individuals or populations can be further identified. WGS enables the identification of Single Nucleotide Polymorphism (SNP), Insertion Deletion (InDel), Structure variation (SV), and Copy Number Variation (CNV). SVs make up a larger portion of the variation base than SNPs and have a greater impact on the genome, which has a significant effect on living organisms. While short-read resequencing is effective in identifying SNPs and InDels, long-read resequencing allows for more precise identification of large fragments and complicated variations.

  • Full-Length mRNA Sequencing-Nanopore

    Full-Length mRNA Sequencing-Nanopore

    While NGS-based mRNA sequencing serves as a versatile tool for gene expression quantification, its reliance on short reads restricts its efficacy in complex transcriptomic analyses. Nanopore sequencing, on the other hand, employs long-read technology, enabling the sequencing of full-length mRNA transcripts. This approach facilitates a comprehensive exploration of alternative splicing, gene fusions, poly-adenylation, and the quantification of mRNA isoforms.

    Nanopore sequencing relies on nanopore single-molecule real-time electrical signals. Guided by motor proteins, double-stranded DNA binds to nanopore proteins embedded in a biofilm, unwinding as it passes through the nanopore channel under a voltage difference. The distinctive electrical signals generated by different bases on the DNA strand are detected and classified in real-time, facilitating accurate and continuous nucleotide sequencing. This innovative approach overcomes short-read limitations and provides a dynamic platform for intricate genomic analysis, includes complex transcriptomic studies.
