Single Nuclei RNA Sequencing Service


Creative Biolabs provides a comprehensive range of customized, high-quality services in single cell nuclei RNA sequencing service to support scientific research in related biomedical industries worldwide, as well as a single-cell level research application platform for complex tissues such as brain tissue, heart, kidney, or some rare cryopreserved samples, making it easier to explore tumor cell heterogeneity and pathogenic mechanisms.

Single Cell Nuclei RNA Sequencing

Single Nuclei RNA Sequencing (snRNA-seq), is an RNA sequencing method for profiling difficult-to-isolate cells, such as those from archived tissues or those that are hard to be dissociated. snRNA-seq methods avoid strong biases against cells of complex morphology and large size and reduce dissociation bias, compatibility with frozen samples, elimination of dissociation-induced transcriptional stress responses. The workflow of snRNA-seq is as follows: isolate nuclei from cells or tissues, cDNA libraries preparation, snRNA-seq, data analysis.

Features & Benefits

Advantages of snRNA-seq

1. The nuclear membrane is more stable than the cell membrane, hence the direct nuclear extraction approach is relatively simple.

2. snRNA-seq can be used with a wide range of materials, including fresh/frozen, complicated tissue types, and no limitation of cell size and activity.

3. There is no "transcription bias" artificially introduced during the dissociation process.

4. The identification of cell types is more comprehensive and complete.

With proven experience and expertise, Creative Biolabs has become a leader in the research of snRNA-seq.

Frequently Asked Questions

Q: Which is better: scRNA-seq, or snRNA-seq

A: scRNA-seq measures both cytoplasmic and nuclear transcripts, while snRNA-seq mainly measures nuclear transcripts. Compared to scRNA-seq, snRNA-Seq is more appropriate to profile gene expression in cells that are difficult to isolate (e.g. adipocytes, neurons).

Q: How to isolate nuclei?

A: We use a quick and mild nuclear dissociation, to minimize technical issues that can affect studies.

Paper Title: Human and mouse single-nucleus transcriptomics reveal TREM2-dependent and TREM2-independent cellular responses in Alzheimer's disease

Sample: Human and mouse brain samples

Published: 2020

Background: Alzheimer's disease (AD) is the most common dementia. Glia have been implicated in AD pathogenesis.  Pathologically, amyloid beta (Aβ) peptides produced by neurons form extracellular aggregates that initiate disease; intraneuronal tau hyperphosphorylation and aggregation ensue, causing neuronal and synaptic dysfunction and cell death.

  • A total of 73,419 individual nuclei were arranged by t-distributed stochastic neighbor embedding (t-SNE) in 2 dimensions. Unsupervised clustering revealed a total of 11 distinct clusters across all samples with cell-type identities as determined by expression of specific markers.
