Our fluorescence-activated cell sorting service supports a broad range of inputs,including whole blood,PBMCs,stem cells,bone marrow aspirates,and tumor cells from clinical samples;tissue samples of human,cynomolgus monkey,and mouse origin;in vitro expanded primary cells;and suspension cell lines. If you are unsure whether your specific sample type is compatible,our flow cytometry team can advise during our initial consultation.
"},{"faq_question":"How many cell populations can be sorted simultaneously?","faq_answer":"Our instruments are capable of sorting up to four populations simultaneously in a single run. Each target population can be defined by up to 12 parameters,and sorting can be based on expression level (low,mid,or high),enabling the isolation of rare cell subpopulations.
"},{"faq_question":"How can you support FACS within a clinical trial?","faq_answer":"CellCarta’s FACS service is designed to meet clinical program requirements. When required,a rigorous GCLP-compliant approach is applied across the full workflow. Flow cytometry specialists engage from initial assay planning through data analysis and reporting,providing a single accountable team for every deliverable. Post-sort purity and viability checks are performed after each run,generating documented quality records that support submission requirements without additional internal QC burden on your team.
"},{"faq_question":"Can CellCarta develop a custom sorting panel?","faq_answer":"Yes. Both standard and custom panels are supported. Cells can be identified using any fluorescence label,including fluorescent antibodies,signaling dyes,proliferation dyes,and viability dyes,and sorted based on expression level (low,mid,or high).
"},{"faq_question":"What delivery formats are available for sorted cells?","faq_answer":"Sorted populations are available in three delivery formats:cryopreserved,freshly isolated,or fixed. The appropriate format is determined by the requirements of your downstream application,including genomic or transcriptomic analysis,single-cell plating,co-culture assays,isolation of tetramer-positive cells,purification of transfected cell lines,or stocking of rare cell types. Our team confirms the right delivery format for your study before the sort begins,ensuring the end product is ready for immediate use in the next stage of your study.
