10x Genomics TCR Sequencing
10x Genomics TCR sequencing is a powerful method for exploring the diversity and detailed characteristics of T-cell receptors (TCRs), which are essential for T-cells to recognize and bind to antigens in the immune response. This technology allows researchers to obtain comprehensive TCR sequence information, including diversity, clonal expansion, and unique sequence traits. In basic immunology, it provides an invaluable tool for systematically studying T-cell development, differentiation, and response mechanisms, revealing the composition and transformation of the TCR repertoire under various conditions.
In cancer immunotherapy research, 10x Genomics TCR sequencing is increasingly utilized to examine T-cells infiltrating tumor environments and identify TCR sequences that interact with tumor-specific antigens. This approach is crucial in determining the T-cells that are pivotal in anti-tumor responses and supports the development of personalized immunotherapies. By pinpointing effective TCR sequences, researchers can engineer TCR therapies tailored to specific tumor antigens, enhancing the precision and efficacy of immunotherapies. Moreover, in infectious disease research, this sequencing method identifies immune responses to specific pathogens by analyzing post-infection TCR repertoire changes, highlighting the T-cells involved in pathogen eradication.
Technical Workflow
1. Sample Preparation
Samples are prepared by extracting single-cell suspensions from patients or experimental models, ensuring the integrity and viability of T-cells, which is critical for successful sequencing. High standards for cell viability and purity are maintained.
2. Single-cell Isolation and cDNA Synthesis
Using microfluidic chip technology, individual T-cells are isolated into separate droplets where their RNA is reverse-transcribed into cDNA. This process ensures distinct TCR information capture for each cell, preventing sequence overlap.
3. Library Construction and Sequencing
The cDNA is then amplified and sequenced using advanced high-throughput platforms, generating extensive TCR sequence data. This data undergoes bioinformatics analysis to uncover TCR diversity and clonal properties.
Advantages and Challenges
1. Advantages
