Frequently Asked Questions
Q1: What types of cells can be used in cytotoxicity testing?
A1: We offer testing on a wide range of cell types, including:
-
Cancer cell lines
-
Primary human or animal cells
-
Stem cells and induced pluripotent stem cells
-
Specialized cell lines for organ-specific toxicity
-
Custom cell lines can also be used upon request.
Q2: How much sample is required for cytotoxicity testing?
A2: The required amount depends on the specific assay type and scale. Typically, a few milligrams of a compound or small volumes of a solution are sufficient. For high-throughput studies, larger quantities may be necessary.
Q3: Can you assess both short-term and long-term cytotoxicity?
A3: Yes, we can perform both acute (24-48 hours) and chronic (up to several weeks) cytotoxicity studies depending on your requirements. Chronic studies are particularly relevant for assessing cumulative toxicity over time.
Q4: Can this service assess selective cytotoxicity?
A4: Yes, we can test selective cytotoxicity by comparing the effects of your compound on cancerous versus healthy cells or different cell types. This is especially useful for evaluating anti-cancer drugs or targeted therapies.
Q5: Can cytotoxicity testing be customized to specific project needs?
A5: We can tailor testing protocols, select specific assays, or include additional endpoints based on your project's objectives, compound type, and regulatory requirements.
Q6: How do you ensure the reliability and reproducibility of results?
A6: We use validated protocols, replicate testing, and advanced data analysis techniques to ensure accurate and reproducible results. Each assay includes positive and negative controls for quality assurance.
Cytotoxicity testing is essential to ensure the safety of your compounds in early-stage development and throughout clinical trials. Our cytotoxicity assessment service offers a wide range of advanced assays and tailored solutions, providing you with the insights needed to move forward with confidence. if you're ready to ensure the safety and success of your drug candidates, reach out to discuss how we can assist with your cytotoxicity testing needs.
