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.

科學家為科學家設計的Panel

可定制且經過驗證的BD Rhapsody Onco-BC乳腺癌靶向Panel是由臨床腫瘤學家合作開發的。

BD Rhapsody Onco-BC乳腺癌靶向Panel結合了來自實驗和數據庫來源的數據，選擇的數據包括已知參與癌癥progression，擴增，上皮 - 間質轉化（EMT）和癌癥干細胞的基因。 包括PAM50基因有助于乳腺癌細胞的分子亞型¹，而免疫分型和基質細胞標志物可以對復雜的腫瘤微環境進行全面調查。

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.

靶向測序的定制文庫

BD Rhapsody Onco-BC乳癌靶向Panel專為BD Rhapsody系統設計，使用多重PCR檢測多達389個基因。細胞在BD Rhapsody Cartridge中裂解后，與mRNA雜交的磁珠被磁性回收用于cDNA合成。包含在BD Rhapsody Onco-BC靶向Panel和BD Rhapsody Supplemental Panel 中的引物用于多輪基因特異性巢式PCR，用于構建文庫。用于測序的zui終PCR產物含有接頭，細胞標記（label），*的分子索引（unique molecular index，UMI）和3'末端高達400bp的靶基因。檢測產物可以在Illumina®MiniSeq，MiSeq，NextSeq，HiSeq2500和HiSeq4000測序儀上進行測序。

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—轉移性乳腺癌樣本的單細胞懸液

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