Analysis of low molecular weight compounds using MALDI- and LDI-TOF-MS: Direct detection of active pharmaceutical ingredients in different formulations
(2017-11-01)
Matrix-assisted laser desorption/ionization mass spectrometry (MALDI-MS) is a high throughput, easy to use analytical technique. The simple sample preparation of this technique and its tolerance to the presence of contaminants ...
Friendly Strategy to Prepare Encoded One Bead−One Compound Cyclic Peptide Library
(ACS Publications, 2013-09-06)
One bead−one peptide libraries allow the screening of suitable ligands for any target protein. Short cyclic peptides are ideal ligands for affinity chromatography because of their high affinity and selectivity for the ...
Water-soluble Cu, Fe, Mn and Zn species in nuts and seeds
(ACADEMIC PRESS INC ELSEVIER SCIENCE, 2010)
An approach was developed to estimate molecular weight distribution of water-soluble Cu, Fe, Mn and Zn species in Brazil nut, cupuassu seed and coconut pulp by size exclusion chromatography (SEC) coupled on-line to ...
In situ assessment of atorvastatin impurity using MALDI mass spectrometry imaging (MALDI-MSI)

Distinguishing two species of Cavernicola (Hemiptera, Reduviidae, Triatominae) with matrix-assisted laser desorption ionization time-of-flight mass spectrometry
(2019-10-01)
The blood-sucking insects of the subfamily Triatominae are vectors of Chagas disease, the most impairing protozoan parasitic infection in Latin America. Among the five tribes known in the subfamily, one of the least studied ...

Cinerascetins, new peptides from Hypsiboas cinerascens : MALDI LIFT-TOF-MS/MS de novo sequence and imaging analysis
(Sociedade Brasileira de Química, 2015-11)
Isolation and sequence determination of peptides in the venom of the spider wasp (Cyphononyx dorsalis) guided by matrix-assisted laser desorption/ionization time of flight (MALDI-TOF) mass spectrometry
(Elsevier B.V., 2001-08-01)
Micro-scale (sub-pmol) isolation and sequence determination of three peptides from the venom of the solitary spider wasp Cyphononyx dorsalis is described. We isolated two novel peptides Cd-125 and Cd-146 and a known peptide ...
