This kit features a convenient selection of pre-qualified standard proteins, matrices, and solvents for calibrating and testing matrix assisted laser desorption ionization (MALDI) mass spectrometers. Configured specifically for applications in the mass range of 5 to 66 kDa, MSCAL3 is ideal for most protein studies. Applications include calibration, tuning, and sensitivity testing of MALDI instruments from all manufacturers.
ProteoMass Protein 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.

The ethanolic extract from Rhodomyrtus tomentosa leaf exhibited good antibacterial activities against both methicillin-resistant Staphylococcus aureus (MRSA) and S. aureus ATCC 29213. Its minimal inhibitory concentration (MIC) values ranged from 31.25-62.5 µg/ml, and the minimal bactericidal concentration (MBC) was 250...

The RdxA oxygen-insensitive nitroreductase of the human gastric pathogen Helicobacter pylori is responsible for the susceptibility of this organism to the redox active prodrug metronidazole [2-(2-methyl-5-nitro-1H-imidazol-1-yl)ethanol]. Loss-of-function mutations in rdxA are primarily responsible for resistance to this therapeutic. RdxA exhibits potent...

In-source decay (ISD) fragmentation as combined with matrix-assisted laser desorption/ionization (MALDI) mass spectrometry allows protein sequencing directly from mass spectra. Acquisition of MALDI-ISD mass spectra from tissue samples is achieved using an appropriate MALDI matrix, such as 1,5-diaminonaphthalene (DAN). Recent...
