Sodium 4-pentynoate is an alkynylacetate analogue, which could be incorporated with cellular proteins and utilized as chemical reporter for the profiling of acetylated proteins [1].
Reversible protein acetylation is generally regulated by lysine acetyltransferases (KATs) and lysine deacetylases (KDACs), which play important roles in regulating gene expression and occurrence of disease [1].
The p300-KAT-catalyzed acetylation with histone protein H3 showed that the the 4-pentynoate group can be efficiently transferred onto lysine residue. In jurkat cells, metabolic labeling of sodium 4-pentynoate was in time and dose dependent, which was optimal at 2.5-10 μM of acetate analogs for 6-8 hr. Fluorescent profiling identified 194 of 4-pentynoate labeled proteins from jurkat cells, where 86% of them were identified by radioactive method and 14% was newly identified [1].

| General tips | Please select the appropriate solvent to prepare the stock solution according to the
solubility of the product in different solvents; once the solution is prepared, please store it in
separate packages to avoid product failure caused by repeated freezing and thawing.Storage method
and period of the stock solution: When stored at -80°C, please use it within 6 months; when stored
at -20°C, please use it within 1 month. To increase solubility, heat the tube to 37°C and then oscillate in an ultrasonic bath for some time. |
