Based on PacBio Circular Consensus Sequences (CCSs), polymerase could copy the same DNA region for several times, which generates high-fidelity, long reads (>99.9% single-molecule read accuracy). Long Amplicon Analysis (LAA) using Single Molecule, Real-Time (SMRT) Sequencing and the Sequel System produces highly accurate and phased CCSs from long amplicons.

与短读测序平台相比,PacBio的长读测序使得对大小从几百个碱基对到10 Kb的扩增子或捕获片段进行测序变得简单。这些长序列对于包括SNP、CNVs和其他通常不需要组装的结构变体在内的变体的可视化非常有用。
博凯森生物提供专业且经济高效的LAA服务,每个样本的测序深度从<500到10K CCS不等,以满足您的特定研究要求。
