introduction : albumin, one of the most important plasma proteins, has a difficult process of synthesis and production. we compared two different methods for albumin purification: carboxymethyl cellulose (cm cellulose) resin exchange and diethylaminoethyl cellulose (deae cellulose) resin exchange in order to determine which resin could be more beneficial. materials and methods : two ion exchang...

albumin has a fundamental role in human body. its main tasks in blood are to regulate osmotic blood pressure, maintaining the ph, and transporting metabolites and drugs throughout the vascular system.  pharmacological studies of the interaction of drugs on hsa are important due to structural and functional changes of this vital protein; thus, here in this research the effect of valproate as a c...

Plasma leakage in severe dengue has been postulated to be associated with skewed cytokine immune responses. In this study, the association of cytokines with vascular permeability in dengue patients was investigated. Human serum samples collected from 48 persons (13 with dengue fever, 29 with dengue hemorrhagic fever, and 6 healthy) were subjected to cytokines analysis by using Luminex Multiplex...

A nested PCR method was developed for the detection of Coxiella burnetii in human serum samples. Two pairs of oligonucleotide primers were designed to amplify a 438-bp fragment of the com1 gene encoding a 27-kDa outer membrane protein of C. burnetii. The primers amplified the predicted fragments of 21 various strains of C. burnetii but did not react with DNA samples from other microorganisms. T...

measles is one of the most contagious human diseases. although mass vaccination programs have reduced the incidence of this disease, measles is still an important cause of morbidity and mortality among children in developing countries. therefore the use of sensitive techniques to evaluate vaccine efficacy and level of immunity among members of susceptible communities is crucial. serum neutraliz...

background and aims: some nanoparticles can be used in immunoassays to increase sensitivity. this study aimed to evaluate a novel nano-immunoassay based on bovine serum albumin nanoparticles (bsa nps). materials and methods: at first, the nanostructure was synthesized, and then applied as a tag in the nano-immunoassay. then the concentration of β-subunit of human chorionic gonadotropin (βhcg) i...

a quantitative analysis method for fudosteine in human serum by high-performance liquid chromatography-electrospray ionization tandem mass spectrometry (hplc-esi/ms/ms) was established, which shows high sensitivity and selectivity. the mobile phase composition was 75% 20 mm acetic acid and 25% acetonitril, which was pumped at a flow rate of 0.40 ml/min. the overall chromatographic run time was ...

background: the immunogenic brucella abortus ribosomal protein l7/l12 is a promising candidate antigen for the development of subunit vaccines against brucellosis. objective: this study was aimed to evaluate the protection of recombinant human serum albumin (has)-l7/l12 fusion protein in balb/c mice. methods: the amplified l7/l12 gene was cloned in pyhsa5 vector, pyhsa5-l7/l12 construct was tra...
