Aflatoxins are a group of fungal toxic metabolites, which are contaminated certain food commodities. ELISA is one of the sensitive methods for detection of aflatoxins. Preparation and stabilizing of a proper conjugated tracer for detection of aflatoxins is probably the main step for designing an ELISA method. In current study, different stabilizers were applied to stabilize a newly prepared con...

The interaction of clarithromycin (CAM) with bovine serum albumin (BSA) was investigated in pH 4.5-8.0 phosphate buffer solutions in which three irreversible reduction waves P(1), P(2) and P(3) of CAM appeared on linear-sweep voltammetry on a static dropping mercury working electrode. In the acidic media, with the addition of BSA into the CAM solution, a new electrochemically active complex was...

Through observations of colloidal gold with silver enhancement, we have demonstrated that 2-nm colloidal gold labeled-testosterone-bovine serum albumin (BSA) conjugate or hydrocortisone-BSA conjugate injected intravenously enters the hormone-target cell nuclei of rats (Nishimura and Ichihara, 1997; Nishimura and Nakano, 1997, 1999). To confirm immunocytochemically whether the nature of BSA in t...

A novel molecularly imprinted optosensing material based on multi-walled carbon nanotube-quantum dots (MWCNT-QDs) has been designed and synthesized for its high selectivity, sensitivity and specificity in the recognition of a target protein bovine serum albumin (BSA). Molecularly imprinted polymer coated MWCNT-QDs using BSA as the template (BMIP-coated MWCNT-QDs) exhibits a fast mass-transfer s...

A 2'-succinyltaxol-bovine serum albumin (BSA) conjugate was prepared as an antigen to produce an anti-taxol monoclonal antibody by immunizing mice. Formation of a linkage between hapten and protein is usually confirmed by the UV or fluorescamine method. However, it was difficult to confirm the binding of 2'-succinyltaxol to BSA by these methods owing to the similar UV absorption maxima of 2'-su...

Mitochondria from a variety of mouse and rat tumors were studied. In general, tumor mitochondria isolated in a medium containing bovine serum albumin (BSA) exhibit respiratory control, while mitochondria isolated from the same tumor in the absence of BSA lack respiratory control. Some variability in oxidative phosphorylation was obtained among the various types of tumors. The rates of phosphory...

OBJECTIVES Pancreatic cancer is one of the most common malignancies of the digestive system, and remains a clinical challenge. This study aimed to assess the effects of bovine serum albumin (BSA) nanoparticles carrying the hMDA-7 gene (BSA-NP-hMDA-7) in the treatment of pancreatic cancer. METHODS BSA-NP-hMDA-7 was generated by nanotechnology and gene recombination technology. A total of 5 BXP...

A novel extracorporeal immunoadsorbent is described in which anti-bovine serum albumin (anti-BSA) was entrapped in collodion membranes adherent to activated charcoal particles. This immunoadsorbent was capable of specifically removing circulating BSA in vitro and in vivo in an extracorporeal system in dogs. In preparation of the immunoadsorbent, up to 81.2% of added anti-BSA was retained on col...

The neoglycoproteins alpha-D-mannose-bovine serum albumin (mannose-BSA) and N-acetyl-alpha-D-glucosamine-BSA (glucNAc-BSA) were shown to rapidly increase intracellular free calcium ([Ca2+]i) in human spermatozoa. The increase in [Ca2+]i induced by these neoglycoproteins accounts for the known ability of these compounds to induce the acrosome reaction in human spermatozoa. Our data support the h...

Supporting Information Proteins were from Sigma and used as received. Antibodies were labelled either with tetramethylrhodamine isothiocyanate (TRITC) or fluorescein isothiocyanate (FITC). Solutions of proteins and adsorption experiments were done in PBS or in PBS-containing 1% BSA. Bis(sulfosuccinimidyl)suberate (BS 3) was from Pierce, aminopropyltriethoxysilane (APTS) from Fluka. PDMS stamps ...
