High Peptide Recovery enabled by Shim-pack Arata technology


              Since the adsorption of peptides to particles is minimized, high recovery of peptides is ensured and excellent peptide analysis can
             be provided by Shim-pack Arata Peptide C18 column.

              Analysis of Tryptic Digest of Myoglobin

              Peptides are known to show non-specific adsorption to particles of LC columns. A Shim-pack Arata Peptide C18 column showed
             high recovery of peptides.
























               Analytical Conditions
                    LC System : NexeraX2MP_M30A (STD Cell)  Detection : 214 nm
                    LC Column : Shim-pack Arata Peptide C18 (2.0 × 150 mm, 2.2 μm)  Column temp. : 40 °C
                    Core shell Peptide C18 (2.1×150 mm, sub 2 μm)  Injection volume : 1 μL
                    Core shell C8 (2.1 ×150 mm, sub 4 μm)  Sample : Angiotensin I
                    Mobile Phase A : 0.1% HCOOH in H2O     Vial : Torast-H Bio Vial
                    Mobile Phase B : 0.1% HCOOH in CH3CN
                    Gradient : 2%B (0-5 min)45%B (20 min)100%B (20.01 – 25 min)
                    2%B (25.01 – 30 min)

             Tryptic digest of myoglobin was analyzed using Shim-pack Arata Peptide C18 (2.2 μm), Core shell C18 (sub 2 μm) and a
             Core shell C8 (sub 4 μm). Compared to the other two columns, Shim-pack Arata Peptide C18 showed significantly larger
             peak area, which suggests that higher recovery could be obtained with Shim-pack Arata Peptide C18 column.
