Metallic markers make direct measurement of protein activity possible‎

Cells operate on rules not vibes, including when on the precipice of persisting or perishing. Yet, with prior research methods, scientists studying this phenomenon had to infer how cells choose to sustain themselves or self-destruct based on the output of their protein factories. While much more advanced than a pundit's vibe check, these analyses were constrained by the inability to account for the activity of these proteins after their construction.
