As an important marker in liquid biopsy technology, CTCs can reflect the more complete biological information of brain tumors. We offer clients a variety of methods based on CTCs detection in brain tumors. In addition, we also provide single-cell sequencing services for CTCs in brain tumors. We can identify individual CTCs or CTM oncogenes and oncogenes, and analyze brain tumor survival factors. This is very critical for real-time monitoring of brain tumor dynamics, assessing treatment efficacy, and personalizing treatment.
