中文名稱：BD Rhapsody Onco-BC 乳癌靶向檢測試劑盒（panel）

用途：與BD Rhapsody單細(xì)胞表達(dá)分析儀配合使用，檢測與乳腺癌和免疫細(xì)胞相關(guān)的 400 個基因

乳腺癌生物學(xué)因復(fù)雜的基因表達(dá)，細(xì)胞異質(zhì)性和患者間的差異而變得復(fù)雜。為了解決這一復(fù)雜性，BD Rhapsody™OncoBC靶向檢測panel使用BD Rhapsody單細(xì)胞分析系統(tǒng)為單細(xì)胞乳腺癌研究提供了一種簡化的檢測方法。 通過集中分析與乳腺癌生物學(xué)zui相關(guān)的基因和標(biāo)志物，減少測序通量，并且降低了與整個轉(zhuǎn)錄組測序相關(guān)時間和測序成本。

BD Rhapsody Onco-BC 靶向檢測試劑盒（panel）

Panel designed by scientists, for scientists

The customizable and validated BD Rhapsody Onco-BC Targeted Panel was created from collaborations with clinical oncologists.

The panel content combines data from experimental and database sources, chosen to include genes with known involvement in cancer progression, proliferation, epithelial-tomesenchymal transition (EMT) and cancer stem cells. Including PAM50 genes aids molecular subtyping of breast cancer cells¹,while immunophenotyping and stromal cell markers enable comprehensive surveys of the complex tumor microenvironment.

Tailored libraries for targeted sequencing

The BD Rhapsody Onco-BC Targeted Panel is designed for the BD Rhapsody system, and uses multiplex PCR for detecting up to 389 genes. After cells are lysed in the BD Rhapsody Cartridge,

beads hybridized with mRNA are magnetically retrieved for cDNA synthesis. Primers included in the BD Rhapsody Onco-BC Targeted Panel and BD Rhapsody Supplemental Panel are used for several rounds of gene-specific, nested PCR for library construction. Final PCR products for sequencing contain adapters, a cell label, a unique molecular index (UMI), and up to 400 bp of the 3’ end of a target gene. Assay products may be sequenced on Illumina® MiniSeq, MiSeq, NextSeq, HiSeq2500 and HiSeq4000 sequencers.

Remarkable panel performance—single-cell suspensions from a metastatic breast cancer sample

In the following example, cryopreserved single-cell suspensions from a disaggregated metastatic breast cancer patient sample were sorted using the BD FACSAria™ system to enrich for live cells. 4,409 cells derived from a lymph node metastasis were profiled using the BD Rhapsody system. Fifteen cell types were detected, including four subpopulations of breast cancer cells and a diverse tumor microenvironment of stromal and major immune cell types. Because the analysis focused on just five percent of the transcriptome, the amount of sequencing is drastically lowered.

的panel性能—轉(zhuǎn)移性乳腺癌樣本的單細(xì)胞懸液

在下面的實(shí)例中，使用BD FACSAria ^TM系統(tǒng)分選來自disaggregated轉(zhuǎn)移性乳腺癌患者樣品的凍存單細(xì)胞懸浮液以富集活細(xì)胞。使用BD Rhapsody系統(tǒng)對來源于淋巴結(jié)轉(zhuǎn)移的4,409個細(xì)胞進(jìn)行分析。檢測到15種細(xì)胞類型，包括4種乳腺癌細(xì)胞亞群和多種腫瘤微環(huán)境（間質(zhì)細(xì)胞和主要免疫細(xì)胞組成）。由于分析只集中在轉(zhuǎn)錄組的5％，因此測序通量極大降低。
