To assess the practical value of BIOMED-2 primers in the diagnosis of ocular adnexal lymphoma by PCR.
DNA was extracted from 63 formalin-fixed paraffin-embedded (FFPE) ocular adnexal lymphoma specimens. The DNA quality was evaluated by PCR-based amplification of housekeeping gene beta-actin. IgH(B) and IgK(B) primers of BIOMED-2 standardized clonality analysis system were used to evaluate the immunoglobin gene rearrangements. PCR products were analyzed using capillary electrophoresis and GeneScan software.
76.2% (48/63) of FFPE samples produced amplifiable DNA for detection of Ig gene rearrangements.Positive detection rates by BIOMED-2 IgH(B) and IgK(B) primers were 79.2% (38/48) and 68.8% (33/48), respectively, with a combined positive detection rate of 91.7% (44/48).
IgH(B) and IgK(B) primers of BIOMED-2 are suitable for the detection of clonal rearrangements of Ig gene using FFPE specimens of ocular adnexal lymphomas.
通过聚合酶链反应(PCR)评估BIOMED-2引物在眼附属器淋巴瘤诊断中的实用价值。
从63例福尔马林固定石蜡包埋(FFPE)的眼附属器淋巴瘤标本中提取DNA。通过基于PCR的管家基因β-肌动蛋白扩增来评估DNA质量。使用BIOMED-2标准化克隆性分析系统的IgH(B)和IgK(B)引物来评估免疫球蛋白基因重排。使用毛细管电泳和GeneScan软件分析PCR产物。
76.2%(48/63)的FFPE样本产生了可用于检测Ig基因重排的可扩增DNA。BIOMED-2 IgH(B)和IgK(B)引物的阳性检测率分别为79.2%(38/48)和68.8%(33/48),联合阳性检测率为91.7%(44/48)。
BIOMED-2的IgH(B)和IgK(B)引物适用于使用眼附属器淋巴瘤的FFPE标本检测Ig基因的克隆重排。
