Seracare Life Sciences Inc TMB 2-Component Microwell Peroxidase Substrate Kit 600mL

Most sensitive chromogenic substrate for peroxidase detection, more sensitive than ABTS and OPD. It develops a deep blue color in the presence of peroxidase-labeled conjugates measurable at 650 nm. Turns yellow when stopped by acidification and read at 450 nm. Recommended for ELISA. TMB can also be used in blotting applications with the purchase of the TMB Membrane Enhancer (50-77-01). 2-component format of 3, 3', 5, 5' - Tetramethylbenzidine, simply mix and use. Has longer shelf life than 1-component TMB substrates.

Item requires ice pack and is temperature sensitive.

Cell Biolabs Inc OxiSelect™ In Vitro ROS/RNS Assay Kit (Green Fluorescence), 96 assays

The OxiSelect™ In Vitro ROS/RNS Assay Kit is an assay for measuring the total free radical presence of a sample. The assay employs a proprietary quenched fluorogenic probe, DCFH-DiOxyQ), which is based on similar chemistry to the popular DCFH-DA. The DCFH-DiOxyQ probe is first primed with a quench removal reagent, and subsequently stabilized in the highly reactive DCFH form. In this reactive state, ROS and RNS species can react with DCFH, which is rapidly oxidized to the highly fluorescent 2’, 7’-dichlorodihydrofluorescein (DCF) . The DCFH-DiOxyQ probe can react with hydrogen peroxide, peroxyl radical, nitric oxide, and peroxynitrite anion. These free radical molecules are representative of both ROS and RNS, thus allowing for measurement of the total free radical population within a sample. The kit has a detection sensitivity limit of 40 nM for H2O2. Each kit provides sufficient reagents to perform up to 96 assays, including standard curve and unknown samples.
