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...

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...
متن کاملA sensitive liquid chromatography–electrospray ionization-mass spectrometry (LC–ESI-MS) method for determination of eperisone
spectrometry (LC–ESI-MS) method for determination of eperisone in human plasma using buflomedil as the internal standard (IS) is established. After being made alkaline with saturated sodium bicarbonate solution, plasma samples are extracted with a mixture of diethyl ether–cyclohexane (1:1, v/v) and separated by highperformance liquid chromatography on a reversed-phase C1 8 column with a mobile ...
متن کاملForensic DNA fingerprinting by liquid chromatography-electrospray ionization mass spectrometry.
The determination of the molecular mass of a DNA sequence has several benefits over conventional fragment-length analysis that are advantageous to the forensic field: (i) sequence variation is captured that increases the power of discrimination compared with that obtained by conventional fragment-length analysis. First experiments showed that this increase makes up to 20%-30% for STR analysis. ...
متن کاملProfiling histidine-containing dipeptides in rat tissues by liquid chromatography/electrospray ionization tandem mass spectrometry.
The histidine-containing dipeptides carnosine (CAR) and structurally related anserine (ANS) and homocarnosine (HCAR), widely distributed in vertebrate organisms, have recently been proposed as endogenous quenchers for highly cytotoxic alpha,beta-unsaturated aldehydes generated by peroxidation. A sensitive, selective, specific and rapid liquid chromatographic/electrospray ionization tandem mass ...
