Quantification of Melittin in Iranian Honey Bee (Apis mellifera meda) Venom by Liquid Chromatography-electrospray Ionization-ion Trap Tandem Mass Spectrometry (LC-ESI-IT-MS/MS)

The current research aimed to quantify melittin (MEL) in Iranian honey bee (Apis mellifera meda) venom. To this end, a liquid chromatography-electrospray ionization-ion trap tandem mass spectrometry (LC-ESI-IT-MS/MS) approach was employed. Melittin is the main toxic peptide of honey bee venom with various biological and pharmacological activities. It was extracted with...

Quantification of Signaling Lipids by Nano-Electrospray Ionization Tandem Mass Spectrometry (Nano-ESI MS/MS)

Lipids, such as phosphoinositides (PIPs) and diacylglycerol (DAG), are important signaling intermediates involved in cellular processes such as T cell receptor (TCR)-mediated signal transduction. Here we report identification and quantification of PIP, PIP2 and DAG from crude lipid extracts. Capitalizing on the different extraction properties of PIPs and DAGs allowed us to efficiently recover b...

LC-ESI-MS/MS : Liquid chromatography-electrospray ionization-ion-trap tandem mass spectrometry

s 39 40 Herbivorous insects can cause deep cellular changes to plant foliage following infestations depending on feeding 41 behavior. Here, a proteomic study was conducted to investigate green peach aphid (Myzus persicae Sulzer) 42 influence as a polyphagous pest on the defense response of Arabidopsis thaliana (L.) Heynh after aphid colony 43 set up on host plant (3 days). Analysis of about 574...
