Small unilamellar vesicles (SUVs) functionalized with an enzyme label and with specific ligands for biological molecules are useful as signal enhancement vehicles in the development of enzyme-linked immunoadsorbent assays and other biosensor applications. Bifunctional vesicles were prepared by covalently attaching horseradish peroxidase (HRP) and an antibody to the outside of the lipid bilayer ...

Correspondence to be addressed to: Dr.T.G. Shrivastav, E-mail:[email protected] Summary Preparation of horseradish peroxidase (HRP) carbamide that is HRP linked to urea (HRP-carbamide/HRP-U) is demonstrated and its potential application in the development of enzyme immunoassays (EIAs) for haptens is described. In this new strategy, the lysine residues of HRP were acylated and then acylat...

Enzyme mimetic is an increasing pull to overcome the limitations on natural enzymes. mimicking done with help of nanozymes. Nanozymes contain nonmaterial which have enzyme-like activity; this similar activity attracts researchers.

Abstract The purpose of the study was to pretreat fermented rooibos biomass with partially purified horseradish peroxidase (HRP) for lignin removal and convert delignified soluble sugars through saccharification a formulated holocellulolytic enzyme cocktail (HEC). HRP extracted from root tissue by membrane filters characterised biochemically. used remove before hydrolysing it HEC. Our findings ...

The endocytosis of ricin, horseradish peroxidase (HRP), and a conjugate of ricin-HRP by monolayer cultures of murine neuroblastoma was studied using morphological and biochemical techniques. The binding of (125)I-ricin and (125)I-ricin-HRP to cells at 4 degrees C, as a function of ligand concentration, was a saturable process. The apparent affinity constants, determined at equilibrium, were 2.8...

To examine the involvement of (pro)renin receptor in the accelerated organ damage in streptozotocin-induced diabetic male SHRsp, the rats fed a high-salt diet were divided into 5 groups: a group treated with the vehicle, a group treated with 15 mg/kg/day of imidapril (ACEi), a group treated with 60 mg/kg/day of imidapril (High ACEi), a group treated with handle region peptide (HRP), and a group...

The C1a isoenzyme of horseradish peroxidase (HRP) is an industrially important heme-containing enzyme that utilizes hydrogen peroxide to oxidize a wide variety of inorganic and organic compounds for practical applications, including synthesis of fine chemicals, medical diagnostics, and bioremediation. To develop a ultra-high-throughput screening system for HRP, we successfully produced active H...

Lunularic acid (LA) inhibited not only the germination and the growth of cress and lettuce at 1 mM but also the gibberellic acid (GA3)-induced alpha-amylase induction in embryoless barley seeds at 120 microM, which was recognized as a specific activity of abscisic acid (ABA). Moreover LA and ABA equally inhibited the growth of Lunularia cruciata A18 strain callus at 40 and 120 microM. A computa...

Transporters within the placenta play a crucial role in the distribution of nutrients and xenobiotics across the maternal-fetal interface. An organic anion transport system was identified on the apical membrane of the rat placenta cell line HRP-1, a model for the placenta barrier. The apical uptake of 3H-labeled organic anion estrone sulfate in HRP-1 cells was saturable (Km = 4.67 microM), temp...

Mesoporous silica nanoparticles coencapsulating gadolinium oxide and horseradish peroxidase (HRP) have been synthesized in the aqueous core of sodium bis-(2-ethylhexyl) sulfosuccinate (AOT)-hexane-water reverse micelle. The average diameter of these silica particles is around 25 nm and the particles are spherical and highly monodispersed as depicted using transmission electron microscopy. The e...
