The LTQ (Linear Trap Quadrupole) system is frequently favored for its speed and sensitivity in tandem mass spectrometry (MS/MS) applications. In my personal setup, I have observed that when we process venom samples—specifically using reduction and alkylation protocols to stabilize disulfide bonds—the LTQ reliably captures the fragmented ions necessary for sequencing.

While MALDI-TOF is excellent for rapid fingerprinting of the crude sample, the LTQ provides the depth needed for de novo sequencing of spider venom peptides. To effectively prepare these, I recommend using 0.2% Rapigest or a similarly mass spectrometry-compatible cleavable surfactant, as it ensures solubility without interfering with downstream ionization.
