BMKMANU S3000_Spatial Transcriptome
Spatial transcriptomics is a technique that allow us to capture and visualize gene expression within tissues. This can be crucial to understand how cells interact.
There are different platforms for this approach. On this matter, BMKGene has developed BMKManu 3000 Spatial transcriptome Chip, a platform that boost the technique performance, reaching subcellular resolution and enabling a multi-level resolution setting.
This chip encloses 4.2 million spots using a patented technology of microwells layered with beads loaded with spatially barcoded probes. With this method, after the capture and amplification, we obtain a cDNA library enriched with the barcoded samples that it’s Illumina compatible.
On the data, the combination of spatial barcode and UMIs ensures the accuracy and specificity of the data generated. Combining all the above, BMKManu provides an extremely versatile data setting.

Single- nuclei 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.

10x Genomics Visium Spatial Transcriptome
Spatial transcriptomics is a cutting-edge technology that allows researchers to investigate gene expression patterns within tissues while preserving their spatial context. One powerful platform in this domain is 10x Genomics Visium coupled with Illumina sequencing. The principle of 10X Visium lies on a specialized chip with a designated capture area where tissue sections are placed. This capture area contains barcoded spots, each corresponding to a unique spatial location within the tissue. The captured RNA molecules from the tissue are then labeled with unique molecular identifiers (UMIs) during the reverse transcription process. These barcoded spots and UMIs enable precise spatial mapping and quantification of gene expression at a single-cell resolution. The combination of spatially barcoded samples and UMIs ensures the accuracy and specificity of the data generated. By using this Spatial Transcriptomics technology, researchers can gain a deeper understanding of the spatial organization of cells and the complex molecular interactions occurring within tissues, offering invaluable insights into the mechanisms underlying biological processes in multiple fields, including oncology, neuroscience, developmental biology, immunology, and botanical studies.
