A real-time PCR assay for quantitation of Kaposi's sarcoma-associated herpes virus (KSHV or human herpesvirus 8) DNA was evaluated. The linear dynamic range was 10 to 10(5) copies of KSHV DNA (r(2) > 0.99). The accuracy of DNA purification and quantitation was less than +/-0.4 log(10) copies for samples that contained from 10 to 10(5) copies of KSHV DNA. Cell-associated KSHV DNA was quantitated over a range of infected cell frequencies from 0. 1 to 10(-5), and cell-free KSHV DNA in plasma was quantitated over a range of 100 to 10(6) copies/ml. Real-time PCR provides a convenient method for quantitation of cell-free and cell-associated KSHV DNA in laboratory and clinical specimens.
对一种用于定量卡波西肉瘤相关疱疹病毒(KSHV或人类疱疹病毒8型)DNA的实时聚合酶链反应检测法进行了评估。线性动态范围为10至10(5)个KSHV DNA拷贝(r(2)>0.99)。对于含有10至10(5)个KSHV DNA拷贝的样本,DNA纯化和定量的准确度小于±0.4 log(10)拷贝。在0.1至10(-5)的一系列感染细胞频率范围内对细胞相关的KSHV DNA进行了定量,在100至10(6)拷贝/毫升的范围内对血浆中无细胞KSHV DNA进行了定量。实时聚合酶链反应为实验室和临床标本中无细胞和细胞相关KSHV DNA的定量提供了一种便捷方法。
