I investigated the toxicity of some chemicals , they are so toxic ,

I did two assays ( Appoptotic DNA ladder and LDH assay) .

I got a results it shows they are apoptosis in DNA ladder assay because the ladder is so clear but in LDH assay ,the results show they are necrotic on the same concentrations the LDH levels increased

So what do you think ,are they nicrotic or apoptotic
