Welcome!
MAPseq (Multiplexed Analysis of Projections by Sequencing) is a novel high-throughput method for brain mapping. MAPseq leverages next-generation sequencing to allow massive multiplexing of long-range projections, from thousands of cells, at single neuron resolution, from a single brain. This method was first described by Anthony Zador’s team (Kebschull et al, 2016 “High-throughput mapping of single neuron projections by sequencing of barcoded RNA”).
BARseq (Barcoded Anatomy Resolved by Sequencing) is a high-throughput, multiplexed method that bridge anatomical and transcriptomic approaches at cellular resolution by in situ sequencing. BARseq uses in situ sequencing to map neuronal projections and correlates neuronal projections to gene expression with high throughput and low cost.
The services in the MAPseq/BARseq core facility include: Sindbis virus barcode library preparation, sample processing for MAPseq(including RNA extraction, and library preparation for sequencing), next generation sequencing, and preliminary data analysis for MApseq. The Core facility also provides consultations and training for BARseq.

| Name | Description | Price | |
|---|---|---|---|
| Cryostat sectioning for manual dissection |
This service provides 200-300 um cryostat sections for manual dissection purpose from fresh frozen tissue. Extra care is taken during cryostat sectioning to avoid cross sample contamination. The sections are stored at -80oC before dissection. |

| Name | Description | Price | |
| Preliminary sequencing data processing |
We offer a preliminary Next Generation Sequencing (NGS) data processing service that includes the analysis of raw data and the generation of a Barcode Matrix, which provides information on the abundance of each barcoded neuron in each tissue sample. Our pricing is based on a per sequencing run basis. Starting from June 1st, 2023, our data processing service will undergo a significant update, resulting in a remarkable drop in the cost of data processing. Our new and improved pipeline is designed to be more efficient and faster, allowing us to deliver high-quality results at a much more competitive price point. This update represents our commitment to providing exceptional value to our users. |

| Test virus order **Free order for non-profit institutes from Oct 2024- Oct 2025** |
This test virus has the same vector sequence as the barcoded virus library, but it contains only one barcode. This virus could be used for practicing Sindbis virus injection. Each order contains 4 aliquots of virus (4ul/aliquot), which should be enough for at least 8 injections. |
