This kit features a convenient selection of pre-qualified standard peptides, matrices, and solvents for calibrating and testing matrix assisted laser desorption ionization (MALDI) mass spectrometers. Configured specifically for peptide applications (in the mass range of 700 to 3500 Da), MSCAL2 is ideal for analysis of tryptic fragments or post-source decay studies. Applications also include calibration, tuning, and sensitivity testing of MALDI instruments from all manufacturers.
ProteoMass Peptide MALDI-MS Calibration Kit has been used as a mass calibration standard for MALDI-TOF MS (matrix assisted laser desorption ionization-time of flight mass spectrometry) analysis.

Phosphatidylinositol (3,4,5)-triphosphate (PtdInsP(3)) mediates intracellular signaling for directional sensing and pseudopod extension at the leading edge of migrating cells during chemotaxis. How this PtdInsP(3) signal is translated into remodeling of the actin cytoskeleton is poorly understood. Here, using a proteomics
