TABLE 1.
Proteins from the two bands identified in Fig. 1, or a control band derived from the hIgG1 lane were identified by mass spectrometry
Shown are the numbers of peptide spectra from each protein (excluding keratins and other contaminants). Peptides from human IgG and TREM2 were presumably derived from the TREM2-Ig fusion used for immunoprecipitation.
| Protein | Number of spectra |
||
|---|---|---|---|
| 36-kDa band | 22-kDa band | Control band | |
| ApoE | 44 | 0 | 0 |
| ApoA-I | 0 | 18 | 0 |
| IgG heavy chain | 15 | 5 | 0 |
| TREM2 | 4 | 1 | 0 |
| ApoD | 2 | 1 | 0 |
| GAPDH | 0 | 0 | 2 |
