3,3',5,5'-Tetramethylbenzidin ≥99%, powder

Supplier: MP Biomedicals

3,3',5,5'-Tetramethylbenzidine is suitable as peroxidase substrate for use in ELISA procedures. The substrate produces a soluble end product that is pale blue in color and can be read spectrophotometrically at 370 or 620 to 650 nm. The TMB reaction may be stopped with 2 M H₂SO₄ (resulting in a yellow color), and read at 450 nm. A sensitive and specific reagent for the detection of blood, assay of hemoglobin, assay of peroxidases. It is useful in gel staining procedure for low levels of home-associated peroxidases and for enzyme immunoassay of horseradish peroxidase.

5,5'-Dithiobis(kyselina 2-nitrobenzoová), Molecular Biology Grade

Supplier: G-Biosciences

Ellman's reagent is a versatile, water-soluble compound for quantifying free sulfhydryl groups in solution. It reacts with a free sulfhydryl group to yield a mixed disulfide and 2-nitro-5-thiobenzoic acid (NTB), a measurable yellow colored product at 412nm.
Ellman's reagent is very useful as a free sulfhydryl assay reagent due to its high specificity for -SH groups at neutral pH, high molar extinction coefficient and short reaction time.
