Ampli1™ LowPass Kit

1™ LowPass Kit applications include the characterization and investigation of genomic heterogeneity and evolution in tumor cell populations such as individual circulating tumor cells (CTCs)


Ampli1™ LowPass Kit is designed to generate multiplexed, sequencing-ready libraries in a streamlined single-day protocol, to detect chromosomal aneuploidies and copy number aberrations (CNAs) by low-pass whole genome sequencing.

Ampli1™ LowPass Kit is compatible with Ion Torrent systems (Ion PGM™ and Ion S5™) and NOW also compatible with Illumina® systems (MiSeq®, HiSeq® 1000/1500, 2000/2500, 3000/4000 and NovaSeq™).

 The Ampli1™ LowPass Kit works exclusively with Ampli1WGA products. The complete workflow takes advantage of the isolation of 100% pure cells with the DEPArray system and balanced whole genome amplification using the Ampli1™ WGA kit. APPLICATIONS_Oncology_CTC_Ampli1.png

Performance of this method has been extensively validated by analyzing the Copy Number profiles of single CTCs and WBCs from cancer patients (see figure below for representative data). 


Low-pass Whole Genome Profile (chr 1-22) of single CTC (upper panel) and WBC (lower panel) isolated with DEPArray Technology from a patient with Lung Adenocarcinoma. Ploidy values are indicated in the y-axis; in the x-axis the alternation of different chromosomes are plotted with different colors. CNAs in the CTC are indicated in red and blue.

Ampli1™ LowPass Kit for Ion Torrent -  Overview:
