Further characterization of the subunits of the giant extracellular hemoglobin of Glossoscolex paulistus (HbGp) by SDS-PAGE electrophoresis and MALDI-TOF-MS
(2011-11-01)
Further characterization of hemoglobin of Glossoscolex paulistus (HbGp) subunits was performed based on SDS-PAGE, size exclusion chromatography (SEC) and MALDI-TOF-MS analysis. SDS-PAGE has shown a total of four linker ...
Identification of bradykinins in solitary wasp venoms
(Elsevier B.V., 2002-03-01)
Bradykinins were identified in three solitary wasp venoms. Purification and characterization of the venom extract of the scoliid wasp Megacampsomeris prismatica led to the identification of bradykinin and threonine(6)-bradykinin ...
Hyaluronidase Alters the Lipid Profile of Cumulus Cells as Detected by MALDI-TOF MS and Multivariate Analysis
(Springer, 2014-09-01)
This research aimed to study the changes in lipid composition in cumulus cells using hyaluronidase according to the intracytoplasmic sperm injection protocol commonly used in human reproduction clinics. the lipid extraction ...
Evaluating and Improving Vitek MS for Identification of Clinically Relevant Species of Trichosporon and the Closely Related Genera Cutaneotrichosporon and Apiotrichum
(Amer Soc Microbiology, 2017)
Trichosporon species are relevant etiologic agents of hospital-acquired infections. High mortality rates are attributed to Trichosporon deep-seated infections in immuno-compromised individuals, making fast and accurate ...
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 ...
Profiling the proteome complement of the secretion from hypopharyngeal gland of Africanized nurse-honeybees (Apis mellifera L.)
(Elsevier B.V., 2005-01-01)
The protein complement of the secretion from hypopharyngeal gland of nurse-bees (Apis mellifera L.) was partially identified by using a combination of 2D-PAGE, peptide sequencing by MALDI-PSD/MS and a protein engine ...
Characterization of gallotannins from Astronium species by flow injection analysis-electrospray ionization-ion trap-tandem mass spectrometry and matrix-assisted laser desorption/ionization time-of-flight mass spectrometry
(Im Publications, 2011-01-01)
The species Astronium urundeuva (Allemao) Engl. and Astronium graveolens Jacq., which are used in Brazilian folk medicine to treat allergies, inflammation, diarrhea and ulcers, were investigated for their composition. The ...
