Once inside the cell, OP-puromycin stops translation by forming covalent conjugates with nascent polypeptide chains.\u003cbr\u003e\nAfter incubation, cells are then fixed with formalin, washed, and permeabilized with detergent.\u003cbr\u003e\nTruncated polypeptides bound to OP-puromycin are then labelled with a fluorescent dye, in a copper-dependent reaction using a fluorescent-azide.\u003cbr\u003e\nCycloheximide, an inhibitor of translation, is used as a negative control. Sytox Green is used as a nuclear counter-stain.\u003cbr\u003e\nUnlike methionine analogs, OP-puromycin does not require methionine-free conditions and can be used to label nascent proteins directly in the cell culture.\u003cbr\u003e\nOther protein synthesis assay kits\u003cbr\u003e\nThis kit ab235634 stains cells that have undergone protein synthesis with 5(6)-TAMRA (Rhodamine), which has a red fluorescence (Ex\/\/Em 540\/580 nm).

Biovision was acquired by Abcam in 2021.\u003cbr\u003e\nCells generate a complete set of proteins during division. Protein synthesis is a tightly regulated process and many critical controls in gene expression occur at the level of translation to ensure that production of specific cellular proteins is quickly turned on\/off under specific conditions (heat chock, starvation, etc.). Protein synthesis is essential in cell growth, proliferation, signaling, differentiation or death; therefore, the identity and amount of the synthesized proteins are critical parameters in determining the physiological state of the cell. Methods enabling detection and characterization of nascent proteins, or changes in spatial and temporal protein expression\/degradation patterns during disease, drug treatment or environmental changes are important tools in assesment of cytotoxicity.\u003cbr\u003e\nThe Safety Datasheet for this product has been updated for certain countries.
