Histamine quantification in human plasma using high resolution accurate mass LC–MS technology

Abstract: Tables, and 27 References A C C E P T E D M A N U S C R I P T ACCEPTED MANUSCRIPTABSTRACT Background: Histamine (HA) is a small amine playing an important role in anaphylactic reactions. In order to identify and quantify HA in plasma matrix, different methods have been developed but present several disadvantages. Here, we developed an alternative method using liquid chromatography coupled with an ultra-high resolution and accurate mass instrument, Q Exactive TM (Thermofisher) (LCHRMS). Methods:The method inclu… Show more

“…Finally, some methods using mass spectrometry have been developed to quantify plasma HA [16,17]. In particular, our team developed an in-house plasma HA quantification assay for diagnostic use based on high Resolution Accurate Mass LC-MS (LC-HRMS) technology [18]. The LC-HRMS method is known to be highly sensitive and specific, averts radioactivity use, and avoids the potential detection of the metabolites of the targeted protein.…”

“…Calibrators were prepared by dilution of the histamine working standard solutions (Toronto Research Chemicals, Toronto, ON) with Tris BSA as a surrogate plasma matrix, as previously described (26) to concentrations ranging from 2.5 to 100 ng/mL. Calibration curves and negative control samples were prepared fresh for each quantitative assay.…”

“…14 LC coupled with tandem mass spectrometry (MS/MS) is also used for HA analysis, where HA- d 4 is used as an internal standard. 15,16 Non-separative methods such as enzyme immunoassaying 17 or radioimmunoassaying (RIA) 18 are also used. Of these methods, RIA is considered to be the gold standard.…”
