Flow Cytometry - Protein Synthesis Assay Kit (Green) (AB239725)
Inhibitory effect of Cycloheximide on nascent polypeptides synthesis.
HeLa (105 cells/ ml) and Jurkat (1X106 cells/ml) cells respectively were pre-treated with vehicle or Cycloheximide for 30 min at 37°C. Subsequently, cells were incubated for additional 30 min with fresh aliquots of media containing either Protein Label or Protein Label and Cycloheximide. Cells were then processed and analyzed by Microscopy and FACS according to the kit protocol. (B) FACS analysis of negative control (white), background (Azide only, blue), positive control (Protein Label, green) and Cycloheximide-treated (pink) cell populations. Signal measured in FL-1 channel clearly shows the inhibitory effect of Cycloheximide on nascent polypeptides synthesis.

Fluorescence Microscopy - Protein Synthesis Assay Kit (Green) (AB239725)
Inhibitory effect of Cycloheximide on nascent polypeptides synthesis.
HeLa (105 cells/ ml) and Jurkat (1X106 cells/ml) cells respectively were pre-treated with vehicle or Cycloheximide for 30 min at 37°C. Subsequently, cells were incubated for additional 30 min with fresh aliquots of media containing either Protein Label or Protein Label and Cycloheximide. Cells were then processed and analyzed by Microscopy and FACS according to the kit protocol. (A) Green fluorescence (upper panel) corresponds to de novo synthesized polypeptides whereas bottom panel shows the inhibitory effect of Cycloheximide on protein biosynthesis. Nuclear staining in both panels confirms that green signal is a result of Protein Label incorporation.

Product details
Protein Synthesis Assay Kit (Green) (ab239725) 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. DAPI is used as a blue 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 ab239725 stains cells that have undergone protein synthesis with 5(6)-FAM (Fluorescein), which has a green fluorescence. It is designed for analysis by fluorescent microscopy or flow cytometry.
This kit contains identical components to Protein Synthesis Assay Kit (Green, Microplate) ab273286, which is designed for use with a fluorometric microplate reader.
Protein Synthesis 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.
