Exploring the Role of DUSP2 in MAPK Signaling — and How to Quantify It Reliably with ELISA Kits
Executive summary DUSP2 (a.k.a. PAC-1) is a nuclear, dual-specificity phosphatase that dephosphorylates MAP kinases—most notably ERK1/2—to tune the amplitude and duration of MAPK signaling. It is strongly induced […]

Quantification of Cellular Polyamines Using Fluorometric Assays: Principles and Optimization
Polyamines—primarily putrescine (PUT), spermidine (SPD), and spermine (SPM)—are small, positively charged aliphatic amines that modulate nucleic acid structure, translation, ion channels, and stress responses. Because they are low-mass, […]
