LDH-A Enzyme Assay

open access: yesBio-Protocol, 2013
LDH (Lactate dehydrogenase) enzyme catalyzes the reversible conversion of pyruvate to lactate using NAD+ as a cofactor. Although the physiological significance of lactate accumulation in tumor cells, a dead-end product in cellular metabolism, is ...

Enzyme-linked immunosorbent assay for urinary albumin at low concentrations [PDF]

open access: yes, 1987
We describe an enzyme-linked immunosorbent assay (ELISA) for urinary albumin. It requires only commercially available reagents, can detect as little as 16 micrograms of albumin per liter, and analytical recovery ranges from 92 to 116%.

The BhbA Enzyme Assay

open access: yesBio-Protocol, 2014
Reductive dehalogenation has been found primarily in anaerobic communities and is originally thought to rarely occur in aerobes. A reductive dehalogenase (BhbA) was characterized from an aerobic strain of Comamonas sp.

Development of an Enzyme-Based Thin-Layer Chromatographic Assay for the Detection of Cyclooxygenase-2 Inhibitors

open access: yesSeparations, 2022
The search for new anti-inflammatory drugs with less side effects requires simple, fast and reliable screening methods. In this context, we have developed a sensitive thin-layer chromatographic (TLC) assay on silica gel plates to detect cyclooxygenase-2 (

Cloning, expression, purification and assay of sorbitol dehydrogenase from "Feicheng" peach fruit (Prunus persica)

open access: yesBrazilian Archives of Biology and Technology, 2013
A gene encoding NAD+-dependent sorbitol dehydrogenase (SDH) in peach fruit was cloned and expressed in Escherichia coli. Recombinant SDH protein with 6×His-tagged was localized exclusively in the cytoplasmic soluble fraction of E.

A method for assaying deubiquitinating enzymes [PDF]

open access: yesBiological Procedures Online, 1998
A general method for the assay of deubiquitinating enzymes was described in detail using (125)I-labeled ubiquitin-fused alphaNH-MHISPPEPESEEEEEHYC (referred to as Ub-PESTc) as a substrate. Since the tyrosine residue in the PESTc portion of the fusion protein was almost exclusively radioiodinated under a mild labeling condition, such as using IODO-BEADS,

Biochemical and computational study of an alginate lyase produced by Pseudomonas aeruginosa strain S21 [PDF]

open access: yesIranian Journal of Basic Medical Sciences, 2020
Objective(s): Alginates play a key role in mucoid Pseudomonas aeruginosa colonization, biofilm formation, and driving out of cationic antibiotics. P. aeruginosa alginate lyase (AlgL) is a periplasmic enzyme that is necessary for alginate synthesis and ...
