最重要的是,低的PD-L1 mRNA显示出很高的阴性预测值,即0.92,说明没有长期受益。 Conclusions 结论 With further validation this assay in low stage patients, assessment of PD-L1 mRNA rather than protein, could be a method to determine which low stage patients should not be treated with ICIs in the ...

If you are targeting a low-abundance gene, you may have trouble getting Ct values in a good, reliable range (Ct > 32). To increase the sensitivity of the assay, you may want to consider the following: - Increase the amount of RNA input into your reverse transcription reaction, if possib...
我们只利用ABI的TagMan assay(茎环结构)来检测成熟的microRNA。这些assays是预先设计并验证过的。 Frank Slack, Phong Trang, & Joanna Weidhaas 耶鲁大学医学院 我们应用的是TaqMan assays。由于micoRNA很短,采取茎环结构的引物会更好。 M.azim Surani & Fuchou Tang 剑桥大学Gurdon Institute ...
