The sequences of TP1–TP10 were analyzed using an Applied Biosystems 494 protein sequencer (Perkin Elmer, USA) (22 (link)). Edman degradation was performed according to the standard program supplied by Applied Biosystems (Shimazu, Kyoto, Japan). The MWs of TP1–TP10 were determined by using a Q-TOF mass spectrometric device combined with an ESI source (47 (link)). Nitrogen was maintained at 40 psi for nebulization and 9 L/min at 350°C for evaporation temperature. The data were collected in the centroid mode from m/z 200 to 2,000.

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.
