    UV-Vis Spectrum of Desmosine

    July 31, 2025
    UV-Vis Spectrum of Desmosine. Absorption Maxima: 235 nm, 270 nm.

    For optimal results in HPLC analysis, it is recommended to measure absorbance at a wavelength that matches the absorption maximum of the compound(s) being analyzed. The UV spectrum shown can assist in selecting an appropriate wavelength for your analysis. Please note that certain mobile phases and buffers may block wavelengths below 230 nm, rendering absorbance measurement at these wavelengths ineffective. If detection below 230 nm is required, it is recommended to use acetonitrile and water as low UV-transparent mobile phases, with phosphoric acid and its salts, sulfuric acid, and TFA as buffers.
    For some compounds, the UV-Vis Spectrum is affected by the pH of the mobile phase. The spectra presented here are measured with an acidic mobile phase that has a pH of 3 or lower.

    Desmosine and isodesmosine are unique amino acids found in elastin, a protein in connective tissue such as elastic arteries, lungs, and skin.

    Desmosine and isodesmosine can be used as specific biological markers for the degradation of mature cross-linked elastin.

    Desmosine can be detected at 270nm using Primesep C mixed-mode reversed-phase cation-exchange column and a mobile phase consisting of acetonitrile (ACN), and water with Ammonium acetate buffer.

    HPLC Method for Analysis of Desmosine

    March 16, 2018

    Application Column

    Obelisc R

    SIELC has developed the Obelisc™ columns, which are mixed-mode and utilize Liquid Separation Cell technology (LiSC™). These cost-effective columns are the first of their kind to be commercially available and can replace multiple HPLC columns, including reversed-phase (RP), AQ-type reversed-phase, polar-embedded group RP columns, normal-phase, cation-exchange, anion-exchange, ion-exclusion, and HILIC (Hydrophilic Interaction Liquid Chromatography) columns. By controlling just three orthogonal method parameters - buffer concentration, buffer pH, and organic modifier concentration - users can adjust the column properties with pinpoint precision to separate complex mixtures.
