El ensayo de HCS de síntesis de proteínas Click-iT® AHA Alexa Fluor® 488 proporciona un método rápido, sensible, no tóxico y no radiactivo para la detección de la síntesis de proteínas nacientes mediante microscopía de fluorescencia y adquisición de imágenes de alto contenido. La AHA Click-iT® es un análogo de aminoácido de la metionina que contiene una fracción de azido. De manera similar a la 35S-metionina, la AHA Click-iT® se alimenta a células cultivadas y se incorpora a proteínas durante la síntesis de proteínas activas. La detección del ácido de amina incorporado utiliza una ligación quimioselectiva o reacción «clic» entre una azida y un alquino, donde la proteína con modificación de azido se detecta mediante el alquino Alexa Fluor® 488 verde fluorescente. El ensayo de HCS de síntesis de proteínas Click-iT® AHA Alexa Fluor® 488 se ha probado con éxito en células A549 y U-2 OS con una variedad de reactivos que inhiben la síntesis de proteínas, entre los que se incluyen la cicloheximida, la anisomicina y la puromicina, tanto en la respuesta a la dosis como en el formato mín.⁄máx.
Para uso exclusivo en investigación. No apto para uso en procedimientos diagnósticos.

  • Preguntas frecuentes

    I am using Click-iT AHA (L-azidohomoalanine) kit to label nascent proteins in live cells, then detecting with TAMRA alkyne after fixation and permeabilization and a click reaction. But I'm seeing nucleolar labeling in the cells. It this expected?

    Yes. All proteins synthesized during the time the AHA is present will be detected, and they may be all over the cell. Our imaging shows strong labeling in the nucleoli and cytoplasm, as well as nuclear labeling.

    Selective identification of newly synthesized proteins in mammalian cells using bioorthogonal noncanonical amino acid tagging (BONCAT).
    Authors:Schuman EM
    Journal:Proceedings of the National Academy of Sciences of the United States of America
    PubMed ID:16769897
    In both normal and pathological states, cells respond rapidly to environmental cues by synthesizing new proteins. The selective identification of a newly synthesized proteome has been hindered by the basic fact that all proteins, new and old, share the same pool of amino acids and thus are chemically indistinguishable. We ... More

    Protein translation has been implicated in different forms of synaptic plasticity, but direct in situ visualization of new proteins is limited to one or two proteins at a time. Here we describe a metabolic labeling approach based on incorporation of noncanonical amino acids into proteins followed by chemoselective fluorescence tagging ... More

    The proteome undergoes complex changes in response to disease, drug treatment, and normal cellular signaling processes. Characterization of such changes requires methods for time-resolved protein identification and imaging. Here, we describe the application of two reactive methionine (Met) analogues, azidohomoalanine (Aha) and homopropargylglycine (Hpg), to label two protein populations in ... More

    Noncanonical amino acid tagging enables the selective fluorescent visualization of newly synthesized proteins in mammalian cells (see the picture). Susceptibility to tagging is determined by the spatial and temporal character of the protein synthesis, thus providing a complement to methods which identify relevant members of the proteome. ... More

    Protein synthesis and autophagic degradation are regulated in an opposite manner by mammalian target of rapamycin (mTOR), whereas under certain conditions it would be beneficial if they occurred in unison to handle rapid protein turnover. We observed a distinct cellular compartment at the trans side of the Golgi apparatus, the ... More
