    • The invention is directed to methods for determining clonotypes and clonotype profiles in assays for analyzing immune repertoires by high throughput nucleic acid sequencing of somatically recombined immune molecules. In one aspect, the invention comprises generating a clonotype profile from an individual by generating sequence reads from a sample of recombined immune molecules; forming from the sequence reads a sequence tree representing candidate clonotypes each having a frequency; coalescing with a highest frequency candidate clonotype any lesser frequency candidate clonotypes whenever such lesser frequency is below a predetermined value and whenever a sequence difference therebetween is below a predetermined value to form a clonotype. After such coalescence, the candidate clonotypes is removed from the sequence tree and the process is repeated. This approach permits rapid and efficient differentiation of candidate clonotypes with genuine sequence differences from those with experimental or measurement errors, such as sequencing errors.
    • 本发明涉及用于通过体细胞重组的免疫分子的高通量核酸测序分析免疫谱的测定中的克隆型和克隆型谱的方法。 在一个方面,本发明包括通过从重组的免疫分子的样品产生序列读数来从个体产生克隆型谱; 从序列形成读取表示每个具有频率的候选克隆型的序列树; 每当这样较小的频率低于预定值,并且每当它们之间的序列差异低于预定值以形成克隆型时,以最高频率候选克隆型任何较低频率候选克隆型聚合。 在这样的聚结之后,从序列树中移除候选克隆型,并重复该过程。 这种方法允许用具有实验或测量误差(例如测序错误)的那些具有真正序列差异的候选克隆型的快速和有效的分化。

    • Methods for determining the methylation status of a plurality of cytosines are disclosed. In some aspects genomic DNA target sequences containing CpGs are targeted for analysis by multiplex amplification using target specific probes that can be specifically degraded prior to amplification. The targets may be modified with bisulfite prior to amplification. In another aspect targets are cut with methylation sensitive or insensitive restriction enzymes and marked with a tag using the target specific probes. The presence or absence of methylation may be determined using methylation sensitive restriction enzyme or bisulfite treatment. Detection in many embodiments employs hybridization to tag arrays, genotyping arrays or resequencing arrays.
    • 公开了确定多种胞嘧啶的甲基化状态的方法。 在某些方面,含有CpG的基因组DNA靶序列靶向用于通过多重扩增进行分析,使用可在扩增前特异性降解的靶特异性探针。 在扩增前可以用亚硫酸氢盐修饰靶标。 在另一方面,用甲基化敏感或不敏感限制酶切割靶标,并使用靶标特异性探针用标签标记。 甲基化的存在或不存在可以使用甲基化敏感的限制酶或亚硫酸氢盐处理来确定。 在许多实施方案中的检测采用与标签阵列,基因分型阵列或重排序阵列的杂交。

    • Methods for multiplex amplification of a plurality of targets of distinct sequence from a complex mixture are disclosed. In one aspect targets are circularized using a single circularization probe that is complementary to two regions in the target that flank a region to be amplified. The targets may hybridize to the circularization probe so that 5′ or 3′ flaps are generated and methods for removing flaps and circularizing the resulting product are disclosed. In another aspect targets are hybridized to dU probes so that 5′ and 3′ flaps are generated. The flaps are cleaved using 5′ or 3′ flap endonucleases or 3′ to 5′ exonucleases. The target sequences are then ligated to common primers, the dU probes digested and the ligated targets amplified.
    • 公开了从复杂混合物多个扩增不同序列的多个靶的方法。 在一个方面,使用单个环化探针对靶标进行环化,所述单个环化探针与靶区域中将要扩增的区域侧翼的两个区域互补。 目标可以与环化探针杂交,从而产生5'或3'的瓣,并且公开了用于去除襟翼和使所得产物环化的方法。 另一方面,目标与dU探针杂交,从而产生5'和3'瓣。 使用5'或3'片段内切核酸酶或3'至5'外切核酸酶切割襟翼。 然后将靶序列连接到常见引物,消化dU探针并扩增连接的靶标。
