DNS-pE

DNS-pE is a 3-phosphoglycerate dehydrogenase (PHGDH) inhibitor with a K_i of 7.4 μM. DNS-pE selectively and irreversibly covalently modifies endogenous PHGDH in live mammalian cells, its vinyl sulfone moiety acts as a fluorescence quencher that becomes highly fluorescent upon covalent modification of PHGDH. DNS-pE can be used as a fluorescent dye for live-cell imaging.

Biological Activity

제품 설명

In Vitro

DNS-pE (10 μM; 1 h) shows robust fluorescence Turn-ON activity with cysteine, achieving a 21-fold increase in fluorescence after 1 h of incubation at room temperature^[1].
DNS-pE (1-50 μM; 3 h) concentration-dependently compets with a clickable IA probe for binding to endogenous PHGDH in live MCF-7 cells^[1].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
