Advantages

Disadvantages

spike-in SILAC

Decoupled mixtures of two kinds of labeling cells with a heavy/light spike-in standard

1. Tissues applicable

2. High coverage

3. Multiple samples comparing(n ≥ 3)

1. High quantification variation

2. Time consuming in sample processing & measuring

3. Limited sample multiplexing

4. Identify a proper spike-in standard based on target proteins and certain sample types.

Triple-SILAC

Mixture of three different labeled cell lines

1. Time saving

2. Low quantification variation

3.No need for SILAC standard

1. Not applicable to tissues

2. More complexity of sample and MS spectra

3. Comparisons for only three samples
