Test process

1. Isolate and collect tumor cells

2. Select target cells through single cell capture platform

3. Automatically generate cell number and picture through our pattern detection software and statistics

4. After picking the target CTC, carry out molecular analysis, such as drug target detection and drug resistance.

Case

Taking breast cancer cell sorting as an example

CD90 positive cells are very rich in the blood of breast cancer patients. These tumor cells (FITC positive, PI negative) can be isolated and collected, and then the enriched circulating tumor cells can be targeted for research

CTC capture by single cell capture platform

Scanning objective: 4x, 10x, 20x, 40x

List file: the number of cells and pictures will automatically generate list documents for query

CTC DNA test

After grabbing the target CTC cells, DNA detection was carried out, and drug-resistant mutations such as ctc-egfr, ctc-kras, ctc-braf, ctc-pik3ca and ctc-tp53 were studied.

ctDNA test

ctDNA-egfr, ctDNA-kras, ctDNA-braf, etc. were detected simultaneously, and were verified with ctc-DNA.
