Profacgen utilizes various methods for protein biotinylation including: Primary amine biotinylation, and Sulfhydryl biotinylation.
Total sulfhydryl (thiol) content was quantified spectrophotometrically after derivatization by Ellmans reagent 5,5'-Dithiobis (2-nitrobenzoic acid) (DTNB) as described by Jongberg et al [21].
Serum free sulfhydryl status is associated with patient and graft survival in renal transplant recipients.
Increased industrial activity, rapid urbanisation and agricultural requirement of chemicals and fertilisers have led to water pollution.3 The amount of As or its metabolites in biological materials such as hair, blood, nails and urine are used as biomarkers of As association.4 After absorption, As accumulates in biological samples such as in hair and nails, and it is thought to be involved in the binding of As to the sulfhydryl groups in keratin.
It is conceivable that plasma GSH levels and GST or GPx activities in fish may be affected by 2,4-D and carbaryl due to that TAS levels reflect antioxidant molecules containing sulfhydryl groups (Erel, 2004).
Arsenic renders its toxic effects by interacting with sulfhydryl groups present in enzymes and interrupt enzymes concerning cellular respiration, which in turn is responsible for blocking glycolysis and Krebs cycle and replace phosphorus in a couple of biological processes6.
Enzyme systems, ischemia-modified albumin, protein carbonyl content, protein sulfhydryl, malondialdehyde, lipid peroxides, and total antioxidant capacity were measured to understand the impact at tissue level.
The DTNB 5,5'-Dithiobis (2-nitrobenzoic acid) disulfide present in the measurement medium is a chromogen and is easily reduced by the sulfhydryl group-containing compounds.
In 1961, Frenkel and Hirsch described strains of streptococci isolated from cases of bacterial endocarditis that grew only in the presence of other bacteria, around which they formed satellite colonies, or in media enriched with sulfhydryl compounds, such as cysteine.
(12) Moreover, CAP has been considered a free-radical scavenger due to its terminal sulfhydryl group.
Also, 4-HNE is a strong electrophile that can change cellular redox state significantly by decreasing cellular sulfhydryl compounds such as glutathione (GSH).
