Alkyne-phenol
Based on 4 publication(s) in Google Scholar
Alkyne-phenol (Alk-Ph) is a clickable ascorbate peroxidase 2 (APEX2) probe. Alkyne-phenol substantially improves APEX-labeling efficiency in intact yeast cells, as it is more cell wall-permeant than APEX2 substrate biotin-phenol (BP). Alkyne-phenol also facilitates the identification of APEX-labeling sites, allowing the unambiguous assignment of membrane topology of mitochondrial proteins. Alkyne-phenol is a click chemistry reagent, it contains an Alkyne group and can undergo copper-catalyzed azide-alkyne cycloaddition (CuAAc) with molecules containing Azide groups.

Activité biologique
Yeast cells expressing Su9-APEX2 are incubated with each probe at 2.5 mM final concentration for half an hour, and the labeling reaction is initiated by the addition of 1 mM H2O2. Alkyne-phenol is the most reactive APEX2 substrate for labeling the yeast proteome[1].
APEX2-mediated Alkyne-phenol labeling in the yeast mitochondria is more effective at probe concentrations above 1 mM[1].
Alkyne-phenol enables proteomic profiling in the mitochondrial matrix of intact yeast cells with exceptionally high specificity (94%), and offers higher coverage than the traditional APEX2 substrate biotin-phenol (BP)[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

APEX2 labeling requires H2O2 and alkyne-phenol (1.2, 2.5 mM, 30 min) to label RNAs. RNA labeling reactions were placed on a nylon membrane to bind to the RNA in a dot blot apparatus and scanned for Cy5 fluorescence in a gel imager. As a control, the RNA samples were incubated for 2 hours with DNase I and RNase A. The RNA was then precipitated before being subjected to the azide-Cy5 click chemistry reaction and was re-precipitated before being filtered on the nylon membrane in the dot blot apparatus.

iBMDMs phagocytosed HRP- or BSA-conjugated beads for 30 minutes at 37° C, followed by washing away extracellular beads and another 30 minutes of incubation at 37° C for phagosome progression. The indicated phenolic labeling substrate (500 μM alkyne phenol (AP) or BP) was added post-wash either 30, 15, or 5 minutes prior to labeling. Labeling was catalyzed with H2O2, click reactions were completed where indicated, and lysates were analyzed by western blot to assess ability of substrate to access the phagosome (representative blot from 3 independent replicates).
