Description

Application

• Lignin degradation by a novel thermophilic and alkaline yellow laccase from Chitinophaga sp.: This study highlights the application of CAPS buffer in stabilizing enzymes under extreme conditions for industrial lignin degradation. The use of CAPS enhances the stability and activity of laccase, pivotal for bio-refining processes (Buzzo et al., 2024).


• Improved Refolding of a Human IgG1 Fc (CH2-CH3) Scaffold from Its Inclusion Body in E. coli by Alkaline Solubilization.: Research demonstrates CAPS buffer′s critical role in the solubilization and refolding of recombinant proteins. This advancement is significant for therapeutic protein production, ensuring higher yield and functionality (Ishikawa et al., 2022).


• An optimized SDS-PAGE protocol with a new blotting system for the initial testing procedure of ESAs in doping control.: This paper utilizes CAPS buffer in the development of a new SDS-PAGE blotting system for doping tests, offering more reliable and faster detection of erythropoiesis-stimulating agents in sports (Martin et al., 2022).


• Insight into organophosphate chemical warfare agent simulant hydrolysis in metal-organic frameworks.: The study uses CAPS buffer to investigate the hydrolysis reactions of chemical warfare agents in metal-organic frameworks. This research is crucial for developing materials that can neutralize hazardous agents safely and efficiently (Ploskonka and DeCoste, 2019).


• Complexometric and argentometric titrations using thread-based analytical devices.: CAPS buffer is applied in novel thread-based analytical devices for environmental monitoring. These devices, utilizing complexometric and argentometric titrations, offer a portable, cost-effective solution for on-site water quality analysis (Jarujamrus et al., 2018).
