A rapid enzymatic fluorometric assay for measuringd-arabinitol in serum was developed using recombinantd-arabinitol dehydrogenase from Candida albicans (rArDH) rArDH was produced in Escherichia coli and purified by dye-ligand affinity chromatography rArDH was highly specific for d-arabinitol cross-reacting only with xylitol (4 9%) among all polyols tested

High purity dyed soluble Azocasein (Sulphanilamide Dyed) for the measurement of enzyme activity for research biochemical enzyme assays and in vitro diagnostic analysis A highly sensitive soluble substrate for the assay of endo-protease activity This substrate has a 5-fold greater sensitivity than similar products supplied by other companies

Histone deacetylases (HDACs) catalyzing the removal of acetyl groups from lysine residues of histone and non-histone proteins play vital roles in regulation of gene transcription In plants HDACs can be grouped into three families including RPD3-type SIR2-type and plant specific HD2-type HDACs Here we describe a method to determine plant HDAC enzymatic activity

Enzyme assays can be split into two groups according to their sampling method: continuous assays where the assay gives a continuous reading of activity and discontinuous assays where samples are taken the reaction stopped and then the concentration of substrates/products determined

The assay range is 0 01-0 5 ng/ml (sensitive assay) and 0 1-10 ng/ml (regular assay) with 300 ul (so with 30 ul the detection range is 0 1-5 ng/ml for the sensitive assay and 1-100 for the regular assay) 5-day double antibody assay Interspecies and human-specific assays are available 1 uU/ml = 0 04 ng/ml 1 uU/ml = 6 pmol/l *Leptin

Enzymes play a key role in insect-plant relationships For a better understanding of these interactions we analyzed Tuta absoluta digestive enzymes Here we describe a detailed protocol for the detection of trypsin and papain-like enzymes in Tuta absoluta larvae by enzyme histochemistry This assay uses frozen and unfixed samples to avoid the loss of enzymatic activity

ABSTRACT

21 04 2020These telomeres consist of tandem repeats of a novel 30-32 bp telomeric r epeat u nit (TRU) and are confirmed by analysing the termini of long reads and through both chromosomal in situ hybridization and a Bal31 sensitivity assay The AalbS3 assembly included previously uncharacterized centromeric and rDNA clusters and more than doubled the content of transposable elements and

endo-1 4-β-Glucanase (endo-cellulase EC 3 2 1 4) is one of the most widely used enzymes in industry Despite its importance improved methods for the rapid selective quantitative assay of this enzyme have been slow to emerge In 2014 a novel enzyme-coupled assay that addressed many of the limitations of the existing assay methodology was reported

Ribosome-inactivating proteins (RIPs) are enzymes that irreversibly inactivate ribosomes as a consequence of their N-glycosylase (EC 3 2 2 22) activity The enzyme cleaves the N-glycosidic bond between the adenine No 4324 from the 28S rRNA and its ribose in rat ribosomes (or the equivalent adenine in sensitive ribosomes from other organisms)

The enzyme activity was completely inhibited by the action of ethylenediaminetetraacetic acid (EDTA) suggesting that the collagenase enzyme isolated from the fish waste is a metalloproteinase enzyme requiring metal ions for enzyme activity Dialysis against KSCN decreased the enzyme total activity and increased its specific activity Sodium dodecyl sulphate polyacryla-mide gel electrophoresis
