A recombinant plasmid has been constructed which contains the mature protein coding region of the human serum albumin (HSA) gene. Bacteria containing this plasmid synthesize HSA protein under control of the E. coli trp promoter-operator. The DNA sequence and predicted protein sequence of HSA were determined from the cDNA plasmid and are compared to existing data obtained from direct protein seq...

Human serum albumin (HSA) is the most abundant protein in the blood plasma. Molecular dynamics simulations of subdomain IIA of HSA and its complex with salicylic acid (SAL) were performed to investigate structural changes induced by the ligand binding. To estimate the binding affinity of SAL molecule to subdomains IB and IIA in HSA protein, binding free energies were calculated using the Molecu...

human serum albumin (hsa) is an important protein that carries variety of substances like some hormones and drugs in blood. pharmacological studies of the interaction of many drugs and hsa are reported during several decades, specially recently years. interaction of cortisol and fluoxetine hydrochloride (flx) (as a common anti-stress drug) with hsa (as their carrier in blood) has been studied s...

The concentration of human serum albumin (HSA) indicates the health state of individuals and is routinely measured by UV spectroscopy with bromocresol. However, this method tends to overestimate HSA, and more critically, depends highly on the timing, in seconds, of the measurements. Here, we report an analog of 2',7'-dichlorofluorescein that can be used as a fluorescent sensor to quantify HSA i...

Choroidal neovascularization (CNV), the advanced stage of age-related macular degeneration (AMD), accounts for >80% of vision loss in AMD. Carboxyethylpyrrole (CEP) protein modifications, uniquely generated from oxidation of docosahexaenoate-containing lipids, are more abundant in Bruch's membrane from AMD eyes. We tested the hypothesis that CEP protein adducts stimulate angiogenesis and possib...

We have investigated the potentiation of transferrin [Tfn]-toxin [Tfn-ricin toxin A chain (RTA) and Tfn-So6 saporin toxin] and monoclonal antibody-RTA conjugates by monensin (Mo) and by a human serum albumin (HSA)-monensin conjugate in vitro. The in vivo survival and in vitro and in vivo toxicity of HSA-Mo were also studied; monensin was chemically linked to HSA carrier protein via a disulfide ...

The in vivo survival and in vitro and in vivo toxicity of HSA-Mo were also studied; monensin was chemically linked to HSA carrier protein via a disulfide b...

The stereoselectivity of the reversible binding interactions between the Dand L-tryptophan enantiomers and serum albumins of different animal species and fragments of human serum albumin (HSA) was investigated by applying three novel high performance liquid chromatographic (HPLC) arrangements. The separations were performed by means of 1) an achiral (diol-bond), 2) a chiral (bovine serum albumi...

The detection of human serum albumin (HSA) is significant clinical importance in disease diagnoses. In this work, polymer-based synthetic receptors are designed by incorporating Ag-ZnS microspheres molecularly imprinted poly(methacrylic acid-co-ethylene glycol dimethacrylate) (MIPs) for the gravimetric HSA. Among different compositions Ag-ZnS@MIPs, MIPs having methacrylic acid and ethylene dime...
