conclusions the prepared antibody can be used for the development of an elisa kit to assay afm1 in milk and other biological fluids. background aflatoxins are the most extensively studied group of mycotoxins produced by molds, especially the aspergillus group, which are highly toxic to animals and humans. objectives since immunoassay is a simple and rapid method for the analysis of many toxic s...

human serum albumin (hsa) is the most abundant protein constituent of blood plasma. this protein consists of a single polypeptide chain of 585 amino acid residues, which has many important physiological functions. hsa can bind and carry many drugs, including anticoagulants, tranquilizers, and general anesthetics. some technique such as: fluorescence spectroscopy, three-dimensional fluorescence ...

background glucose is an essential element in the supply of body’s energy. in diseases such as diabetes, glucose increase is associated with disturbance in metabolism. cortisol is an important hormone in the regulation of glucose metabolism, and human serum albumin (hsa) is one of the most important glucose and cortisol transmitters in blood. interaction between albumin and these ligands could ...

three new rimantadine schiff bases (rsbs) were prepared, and then the interaction of rsbs with bovine serum albumin (bsa) was investigated using fluorescence, synchronous fluorescence, uv-vis absorption spectroscopy under physiological conditions. the results showed that the three rsbs effectively quenched the intrinsic fluorescence of bsa via static quenching. binding constant (ka), number of ...

mechanism of the binding of lomefloxacin (lmf) with human serum albumin has been studied at physiological ph (7.4) using fluorescence spectroscopic technique. lmf is a third-generation fluoroquinolone antibiotic that exhibits striking potency against a broad spectrum of gram-negative and gram-positive bacteria through inhibition of dna gyrase. lomefloxacin is a drug that is excreted in urine an...

showing the occurrence of glass/rubber transition in bovine serum albumin (a globular protein) atlow moisture levels and the occurrence of maillard crosslinking in gelatin in previous works, the importanceof the state of glass or rubber of bsa on the rate and extent of polymerisation, protein solubility, colour andsds page patterns in the presence and absence of ascorbic acid, diketogulonic aci...

conclusions in this study, a low albumin level (≤ 3 mg/dl) was an indicator of nutritional status. patients’ albumin levels, bmi, nutritional status, apache ii score, and sofa score were associated with mortality. age in itself did not predict mortality in the elderly. objectives in this study, the effect of body mass index (bmi) and albumin values at first admission to the icu on the course an...

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...

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...
