The enzyme expressed stably in V79 cells predominantly catalyzed the glucuronidation of simple, planar phenols (e.g., for 1-naphthol, K (m) = 41 microM, V (max) = 0.07 nmol/min/mg protein), a class of compounds extensively glucuronidated by human UGT1A6.

And the horseradish peroxidase labeled protein A conjugate which was bounded to the SjAb by a "sandwich" format was used as a biocatalyst for the oxidative precipitation of 4-chloro-1-naphthol by H (2) O (2) to yield the insoluble product benzo-4-chlorohexadienone, resulting in an amplified mass sensing of antigen-antibody interaction.

Alcohol-solubilized zein is spotted onto chromatography paper disks or strips, incubated with antiserum (30-60 min), washed with several changes of Tris-buffered saline (10 min), incubated with protein A-peroxidase (30 min), and washed with several changes of Tris-buffered saline (10 min). the binding of zein-specific antibody is visualized by peroxidase-catalyzed color production from 4-chloro-1-naphthol.

The virus-bound antibodies were located by protein A-peroxidase or protein A-alkaline phosphatase conjugate followed by the peroxidase substrate mixture, 4-chloro-1-naphthol and H2O2, in the first case or the alkaline phosphatase substrate mixture, 5-bromo-4-chloro-3-indolyl phosphate and Nitroblue tetrazolium in the second case.

All activities, however, were immunoadsorbed in the presence of protein A-Sepharose.
This enzyme had a broad substrate specificity and was mainly responsible for the microsomal capacity to glucuronidate testosterone, 1-naphthol, and morphine.

On the basis on heterogeneous competitive enzyme formats, three assay types were used: immobilized antibodies (direct format), immobilized hapten conjugates (indirect format), and capture format based on immobilized protein A/G.
Monoclonal and polyclonal antibodies for carbaryl and 1-naphthol were used to develop sensors in different organic solvent mixtures.

The strips were incubated with test samples and later with horseradish peroxidase (HRPO) labelled protein-A conjugate.
A dark blue spot was obtained by treatment with peroxidase substrate, 4-chloro-1-naphthol, in positive samples.

A synthetic bifunctional ligand (22/8) comprising a triazine scaffold substituted with 3-aminophenol (22) and 4-amino-1-naphthol (8) has been designed, synthesised, characterised and immobilized on agarose beads to create a robust, highly selective affinity adsorbent for human immunoglobulin G (IgG).
The adsorbent shows similar selectivity to immobilized protein A and binds IgG from a number of species.

The novel approach consists of the expression of a N-terminal UGT polypeptide fused to Staphylococcus aureus protein A in Escherichia coli and a single step purification of the fusion protein by immunoaffinity chromatography.
In human liver microsomes, specific immunoinhibition analysis demonstrated that glucuronidation by UGT1*6 represented 20 to 50% of the total 1-naphthol UGT activity with a good correlation with the amount of protein selectively quantified on immunoblot.

Enzymic activity was evidenced using the substrate 4-chloro-1-naphthol.
