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 DNA Double Strand Break (DSB) Staining Kit, Trial Size
STA-321-T 20 assays
EUR 351
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.

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.

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.

OxiSelect N?-(carboxymethyl) lysine (CML) Competitive ELISA Kit, Trial Size
STA-816-T 32 assays
EUR 421
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 Competitive ELISA kit specifically detects CML formation with a high level of sensitivity. This is a Competitive ELISA Kit in which the plate is coated with a CML conjugate.  Standards and unknown samples are added to the plate, followed by incubation with the primary antibody. The CML in the unknown samples and the CML attached to the plate compete for the primary antibody. Higher CML content in unknown samples results in more binding of the antibody to the sample, and thus less antibody binds to the plate. Since the antibody bound to the sample is washed away, higher CML content in samples correlates with a lower signal.

STA-817-T 32 assays
EUR 398
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 (Figure 1).

QuickTiter Lentivirus Titer Kit (Lentivirus-Associated HIV p24), Trial Size
VPK-107-T 32 assays
EUR 409
Description: Measuring the HIV-1 p24 antigen is a long-established method for lentivirus quantitation. However, the traditional p24 ELISA detects both virus-associated p24 and free p24 generated by 293 cells during transient transfection. Free p24 can account for a substantial portion of total p24 in the supernatant. Therefore, the ELISA typically overestimates the quantity of lentivirus present. Our QuickTiter Lentivirus Titer Kit (Lentivirus-Associated HIV p24) substantially minimizes this problem. A proprietary technology separates the lentivirus from free p24 in solution prior to running the ELISA portion of the assay.

Description: Accurate measurement of adenovirus titer is critical for gene delivery. Traditional plaque-forming unit (PFU) assays are long and suffer from high inter-assay variability. The QuickTiter Adenovirus Titer Immunoassay Kit provide a quick, complete system to functionally titer virus infectivity. The assay recognizes all 41 serotypes of adenovirus, and can be used with any adenovirus system that can amplify in HEK 293 cells.
