UK biologist reveals bacterial antibodies were incorrectly used in mammalian aging…
Over fifty flawed cell ageing papers relied on bacteria-based reagents instead of the correct mammalian ones, invalidating future disease prediction models.
A UK molecular biologist revealed that over 50 studies incorrectly used bacterial antibodies instead of mammalian ones, leading to unreliable results in cell ageing research.
- David identified at least 54 papers where researchers mistakenly used E. coli antibodies targeting β-galactosidase instead of mammalian targets.
- Cross-reactivity between bacterial proteins and mammalian cells is unsupported by evidence, causing false positives in senescence detection via immunostaining or western blotting.
- While some authors admit the mistake occurred, others claim it did not affect conclusions because ancillary data was collected; however, this oversight risks propagating errors through AI literature reviews that predict which proteins are good targets for disease treatments.
