Amperometric detection of Enterobacteriaceae in river water by measuring β-galactosidase activity at interdigitated microelectrode arrays.

Anal. Chim. Acta 677 , 156-161, (2010)

Two simple methodologies are compared for the detection of faecal contamination in water using amperometry at gold interdigitated microelectrodes. They rely on the detection of β-galactosidase (β-gal) by redox cycling amperometry of the p-aminophenol (PAP) pr...

Sugar coated liposomal flavonoid: a unique formulation in combating carbontetrachloride induced hepatic oxidative damage.

J. Drug Target. 13(5) , 305-15, (2005)

Rats were administered a single dose of plant origin phenolic antioxidant Quercetin (QC) in free, liposome encapsulated and galactosylated liposome encapsulated forms 2 h prior to hepatotoxic dose of carbontetrachloride (CCl4, 40% v/v in olive oil, 1 ml/kg b....

Immunogenicity of galactosylated liposomes.

Immunol. Commun. 13(1) , 5-13, (1984)

The kinetics of the immune response to galactosylated liposomes in saline was studied in rabbits. The antibody level in the secondary immunization was found to be higher compared to that in the primary response. The antibodies were purified on an immunoadsorb...

Effect of membrane composition on the immune reactivity of galactosylated liposomes.

Quantum dot based fluorometric detection of cancer TF-antigen.

Anal. Chem. 85(20) , 9699-704, (2013)

Cancer is a major global health challenge that would benefit from advances in screening methods for early detection that are rapid and low cost. TF-antigen is a tumor-associated antigen displayed on cell surface proteins of a high percentage of human carcinom...

Specific and reversible immobilization of proteins tagged to the affinity polypeptide C-LytA on functionalized graphite electrodes.

PLoS ONE 9(1) , e87995, (2014)

We have developed a general method for the specific and reversible immobilization of proteins fused to the choline-binding module C-LytA on functionalized graphite electrodes. Graphite electrode surfaces were modified by diazonium chemistry to introduce carbo...

Fast electrochemical detection of anti-HIV antibodies: coupling allosteric enzymes and disk microelectrode arrays.

Anal. Chim. Acta 641 , 1-6, (2009)

Here a novel electrochemical method for the rapid detection of anti-HIV antibodies in serum is presented. The novelty lies in the combination of allosteric enzymes and coulometry to yield a fast, simple and reliable HIV diagnostic method. We have used a previ...

Electrochemical detection of quorum sensing signaling molecules by dual signal confirmation at microelectrode arrays.

Anal. Chem. 83 , 2097-2103, (2011)

n-Acyl homoserine lactones (AHLs) are produced by gram-negative bacteria to regulate gene expression in a cell density dependent manner. For instance, expression of virulence factors by pathogens such as Pseudomonas aeruginosa is induced only when a threshold...

[Chemical attachment of p-aminophenylgalactoside to acid alpha-glucosidase from human liver].

Biokhimiia 47(7) , 1141-6, (1982)

Chemical modification of the COOH-groups of acid alpha-glucosidase from human liver by 1-ethyl-3 (3'-dimethylaminopropyl) carbodiimide. HCl in the presence of rho-aminophenyl-beta-D-galactopyranoside was carried out. The presence of covalently bound galactose...

[Antibodies against p-aminophenyl-beta-D-galactopyranoside-containing proteins].

Biokhimiia 48(5) , 851-6, (1983)

The antibodies were prepared from antisera of rabbits immunized with bovine serum albumin containing covalently bound p-aminophenyl-beta-D-galactopyranoside (APG) and purified by affinity chromatography on APG-containing ovalbumin immobilized by BrCN-activate...
