Analytical Stability and Higher Detection
Analytical Stability and Higher Detection
Baseline Stability
PPSQ series protein sequencers separate PTH-amino acids isocratically. This improves baseline stability and allows high-sensitivity analysis of PTH-amino acids.
Retention Time Reproducibility
Isocratic sequence analysis provides more stable retention times. Therefore, peaks detected in previous cycles can be cancelled using substation chromatogram processing, making it easier to identify sequences.
Higher Detection
Cycle 10 PTH-Val
PPSQ-51A/53A
PPSQ-31B/33B
Cycle 21 PTH-Ile
PPSQ-51A/53A
PPSQ-31B/33B
Sample: Horse myoglobin 10pmol
Results show the subtraction chromatograms by SPD-M30A (PPSQ-51A/53A) and SPD-20A (PPSQ-31B/33B) connected tandemly after Edman degradation.
