TABLE. Mass spectrometry analysis of proteins in MIN6.EXO. EXO prepared from MIN6 insulinoma cell culture supernatant (50 µg) was submitted to the mass spectrometry facility in the Scripps Research Institute (San Diego, CA) for protein identification. The result is shown in the third column, MIN.EXO. For column #4-7, total 100 µg of EXO proteins were separated on a 10% Tris-HCl polyacrylamide gel. The gel was divided into 4 slices, M1, M2, M3 and M4, as indicated in Fig. 1B. Each slice was analyzed in mass spectrometry, and protein contents are listed in the rest columns labeled as MIN6.M1, MIN6.M2, MIN6.M3 and MIN6.M4, respectively for each slice.
