Applicazioni
4-Hexylphenylazosulfonate (Azo) is a photocleavable anionic surfactant developed by the Ge lab for use in high-throughput top-down and bottom-up proteomics by mass spectrometry (MS). Initially, the reagent showed a breakthrough as an improved method for top-down analysis [Brown et al. 2019]. Top-down analysis looks at intact proteins, while bottom-up analysis uses digested proteins. Of the two, top-down analysis is preferable for detecting post-translational modifications and sequence variations. Bottom-up is more commonly used and is likely to detect more proteins. This reagent was also shown to work for sample extraction that can be used for both top-down and bottom-up analysis on the same sample to maximize data collection[Brown et al. 2020].
Surfactants are required for protein extraction especially for challenging classes of protein including membrane proteins[Brown et al. 2020] and extracellular matrix proteins[Knott et al. 2020], but surfactants suppress the signal in MS. While removing a surfactant will improve the signal, this can cause protein loss and degradation. Azo allows for easy removal since it can be rapidly degraded using ultraviolet irradiation (λmax = 305 nm). Using Azo in this way reduces protein loss and gives an improved signal. Please see the Ge lab publications for information on using this product [Brown et al. 2019, Brown et al. 2020, Knott et al. 2020, and Aballo et al. 2021].

Mass spectrometry (MS)-based proteomics provides unprecedented opportunities for understanding the structure and function of proteins in complex biological systems; however, protein solubility and sample preparation before MS remain a bottleneck preventing high-throughput proteomics. Herein, we report a high-throughput bottom-up proteomic

We report the identification of a photocleavable anionic surfactant, 4-hexylphenylazosulfonate (Azo), which can be rapidly degraded by ultraviolet irradiation, for top-down proteomics. Azo can effectively solubilize proteins with performance comparable to that of sodium dodecyl sulfate (SDS) and is compatible
