An Eksigent 425 system was coupled to an AB Sciex TripleTOF 5600+ mass spectrometer. The liquid chromatography system uses a trap column (ChromXP 5 μm ChromXP C18CL 120 Å 10×0.3mm) and an analytical column (Eksigent 3 μm ChromXP C18CL 120 Å 150×0.3mm). The analytical column temperature was maintained at 35 °C. LCMS grade solvents were purchased from Honeywell and composed of buffer A (0.1% formic acid in water (v/v)) and buffer B (0.1% formic acid in acetonitrile (v/v)). Peptides were reconstituted in 10μl 2% solvent B and 8μl was loaded at 10 μl/min for 3 minutes onto the trap column. Analytical separation was established by maintaining 3% B during loading. After a valve switch event, peptides were resolved using the analytical column at a flow rate of 5 μl/min with a linear gradient of 3–25% HPLC buffer B for 38 minutes, followed by a 5 min linear gradient to 32% B. Following the peptide elution window, in 2 min the gradient was increased to 80% B for 3 min. Initial chromatographic conditions were restored in 1 min and maintained for 8 min.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
