OxiSelect Oxidative DNA Damage Quantitation Kit (AP Sites), Trial Size

STA-324-T 10 assays
EUR 498
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 DNA Double-Strand Break (DSB) Staining Kit

STA-321 100 assays
EUR 790.8
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.

EUR 664.8
Description: MDA, or malondialdehyde, is a widely accepted marker for oxidative stress. Our OxiSelect MDA Immunoblot Kit provides a specific method for detection of this lipid peroxidation by-product. 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.

OxiSelect DNA Double Strand Break (DSB) Staining Kit, Trial Size

STA-321-T 20 assays
EUR 421.2
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 N?-(carboxymethyl) lysine (CML) Competitive ELISA Kit

STA-816 96 assays
EUR 957.6
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.
