製品の詳細

Protein Synthesis Assay Kit (Green, Microplate) (ab273286) utilizes a novel and robust chemical method based on an alkyne-containing, cell-permeable analog of puromycin, O-Propargyl-puromycin (OP-puromycin).

Protein synthesis assay principle
In the protein synthesis assay, cultured cells are incubated with OP-puromycin. Once inside the cell, OP-puromycin stops translation by forming covalent conjugates with nascent polypeptide chains.
After incubation, cells are then fixed with formalin, washed, and permeabilized with detergent.
Truncated polypeptides bound to OP-puromycin are then labelled with a fluorescent dye, in a copper-dependent reaction using a fluorescent-azide.
Cycloheximide, an inhibitor of translation, is used as a negative control. Sytox Green is used as a nuclear counter-stain.

Unlike methionine analogs, OP-puromycin does not require methionine-free conditions and can be used to label nascent proteins directly in the cell culture.

Other protein synthesis assay kits
This kit ab273286 stains cells that have undergone protein synthesis with 5(6)-FAM (Fluorescein), which has a green fluorescence. It is designed for analysis by fluorometric microplate reader.
This kit contains identical components to Protein Synthesis Assay Kit (Green) ab239725 which is designed for analysis by fluorescent microscopy or flow cytometry.
Protein Synthesis Assay Kit (Red) ab235634 stains cells that have undergone protein synthesis with 5(6)-TAMRA (Rhodamine), which has a red fluorescence (Ex//Em 540/580 nm). It is designed for analysis by fluorescent microscopy or flow cytometry.

Other Notes
This product was previously called K467 Biovision EZClick™ Global Protein Synthesis Assay Kit and Global Protein Synthesis Assay Kit. Biovision acquired Abcam in 2021.
