I am wondering what people recommend for cell killing assays and platforms. I am particularly interested in looking at T cells and using the assays/ platforms in preclinical developmnent and for testing of clinical products such as CAR or TIL etc.
If you're looking for something more budget conscious, consider soluble viability assays like MTS or WST-8. Or LDH as a death assay.
Finally consider time-lapse video recording as a way to validate the assays visually. The high priced option for that would be something like the Thermo CX5. Or on the low-price end just throw a phase contrast scope with a digital camera into the incubator. Cancer killing videos make great promotional material.
