Infrared laser ablation and capture of enzymes with conserved activity
Wang, K., Donnarumma, F., Baldone, M. D., & Murray, K. K. Infrared laser ablation and capture of enzymes with conserved activity. Anal Chim Acta, 1027, 41โ46 (2018). Abstract Infrared (IR) laser ablation at 3โฏฮผm wavelength was used to extract enzymes from tissue and quantitatively determine their activity. Experiments were conducted with trypsin, which was ablated, …
