OxiSelect Total Glutathione (GSSG/GSH) Assay Kit, Trial Size

STA-312-T 20 assays
EUR 282
Description: The OxiSelect Total Glutathione Assay Kit is a quantitative assay for measuring the total glutathione content within a sample (GSH/GSSG).  Glutathione Reductase reduces oxidized glutathione (GSSG) to reduced glutathione (GSH) in the presence of NADPH.  Subsequently, the  chromogen reacts with the thiol group of GSH to produce a colored compound that absorbs at 405 nm.  The total glutathione content in unknown samples is determined by comparison with the predetermined glutathione standard curve.  The rate of chromophore production is proportional to the concentration of glutathione within the sample.  The rate can be determined from the absorbance change over time.  Metaphosphoric acid is provided to remove interfering proteins or enzymes from samples.

OxiSelect Myeloperoxidase Chlorination Activity Assay Kit (Colorimetric)

STA-803 200 assays
EUR 554
Description: Myeloperoxidase (MPO) is a heme-based peroxidase enzyme responsible for antimicrobial activity against a wide range of organisms. It has also been found to be correlated with increased oxidative stress and decreased levels of catalase activity. The OxiSelect Myeloperoxidase Chlorination Activity Assay Kit is a quantitative, colorimetric assay for measuring the myeloperoxidase activity within a sample.

OxiSelect Myeloperoxidase Peroxidation Activity Assay Kit (Fluorometric)

STA-805 192 assays
EUR 577
Description: Myeloperoxidase (MPO) is a heme-based peroxidase enzyme responsible for antimicrobial activity against a wide range of organisms. It has also been found to be correlated with increased oxidative stress and decreased levels of catalase activity.

OxiSelect s-Glutathione Adduct Competitive ELISA Kit

STA-814 96 assays
EUR 624
Description: Glutathione helps protect cells from free radical damage as an antioxidant, but it can also covalently attach to proteins through its sulfhydryl moiety upon derivatization by reactive oxygen species (ROS). Glutathione protein adducts can therefore serve as a marker of oxidative stress. OxiSelect s-Glutathione Adduct Competitive ELISA Kit quantifies the glutathionylation of proteins in a standard 96-well plate.

OxiSelect Hydrogen Peroxide/Peroxidase Assay Kit (Colorimetric)

STA-844 500 assays
EUR 531
Description: The OxiSelect Hydrogen Peroxide/Peroxidase Assay Kit is a sensitive colorimetric assay for hydrogen peroxide or peroxidase. The H2O2 or peroxidase content in unknowns is compared with a standard curve. 500 assays/kit.

OxiSelect N-epsilon-(Carboxymethyl) Lysine (CML) Immunoblot Kit

STA-313 10 blots
EUR 531
Description: Advanced glycation end products (AGE) are formed during the Maillard reaction where reducing carbohydrates react with lysine side chains and N-terminal amino groups of various macromolecules, particularly proteins. The advanced glycation end products can adversely affect the fuction of these macromolecules. One of the most prevalent AGE products, N-epsilon-(Carboxymethyl) Lysine, has been implicated in oxidative stress and vascular damage. The OxiSelect N-epsilon-(Carboxymethyl) Lysine Immunoblot kit specifically detects CML formation in protein samples.

OxiSelect DNA Double-Strand Break (DSB) Staining Kit

STA-321 100 assays
EUR 659
Description: Double-strand breaks (DSB) in DNA are among the most dangerous types of DNA damage occuring within cells. One of the earliest cellular responses to double-strand breaks is the phosphorylation of a histone variant, H2AX, at the sites of DNA damage. Within seconds Ser139 is phosphorylated when DSBs are induced in mammalian cells. Phosphorylation of this serine residue causes chromatin condensation and appears to play a critical role in the recruitment of repair or damage-signaling factors to the DNA damage sites. The OxiSelect DNA Double-Strand Break Staining Kit provides an easy-to-use method for detecting the presence of DSBs in cells cultured in microtiter plates. Double strand breaks can be detected in just a few hours by immunofluorescence staining of the phosphorylated histone H2AX.

OxiSelect Oxidative DNA Damage Quantitation Kit (AP sites)

STA-324 50 assays
EUR 780
Description: DNA damage can manifest in the formation of apurinic or apyrimidinic (AP or abasic) sites. Such spontaneous base loss in mammalian cells has been estimated at between 50,000 and 200,000 sites per day. Unrepaired abasic sites can inhibit transcription and may be mutagenic. Our OxiSelect Oxidative DNA Damage Quantitation Kit provides a simple, user-friendly method for the quantitaiton DNA damage in the form of abasic sites. The assay uses an Aldehyde Reactive Probe (ARP) to specifically react with an aldehyde group on the open ring of the AP site. This allows the AP site to be labeled with Biotin, followed by detection with Streptavidin-Enzyme conjugate.

OxiSelect TBARS Assay Kit (MDA Quantitation), Trial Size

STA-330-T 20 assays
EUR 340
Description: The TBARS (Thiobarbituric Acid Reactive Substances) assay is well-established for screening and monitoring lipid peroxidation. MDA forms a 1:2 adduct with thiobarbituric acid; the MDA-TBA adduct can then be measured. Our OxiSelect TBARS Assay Kit provides a much more user-friendly protocol to measure the MDA-TBA adduct. Reaction volumes are much smaller than the traditional assay, so much less sample is required. Also, reactions can be performed in standard polypropylene tubes - no glass tubes or glass marbles are required. Important Note: MDA adducts are not stable long term. For best results test all samples immediately upon collection, or freeze them at -80ºC for up to one month. MDA may be degraded in samples that have been frozen for longer periods; in such cases more reliable results may be obtained from more stable markers of oxidative stress such as protein carbonyl, 8-OHdG or 4-HNE.
