RNase H activity in a convenient and sensitive colormetric assay that delivers results in real time. Great for Quality Testing for RNase H activity in enzyme preparations and determination of RNase H unit activity.
Attogene has developed the first of its kind and patent pending technology that uses a novel RNA/DNA substrate tagged on the 5′ and 3′ end with a Biotin that is attached to our streptavidin colloidal gold reporter molecules and a test line tag. In the absence of RNases H, the gold tagged RNA/DNA molecule will flow up the lateral flow strip and bind to the test line using an anti tag antibody (INDICATING that NO RNase H is detected). When RNases H is present or added, however, the RNA strand of the RNA/DNA substrate is cleaved, and the Biotin tagged 5′ and 3′ tags are spatially separated in solution cauing the test line to disapear.
This test can be used to rapidly and efficiently detect ribonucleases H activity and is a perfect tool for monitoring unit activity or residual RNAse H activity.
The Aflatoxin M1 plate kit is a competitive enzyme-labeled immunoassay. The Aflatoxin M1 sample extract and calibrators are pipetted into the test wells followed by the Aflatoxin M1 antibody into the test wells to initiate the reaction. During the 30 minutes incubation period, Aflatoxin M1 from the sample and Aflatoxin M1 antigen compete for binding to the Aflatoxin M1 antibody. The Aflatoxin M1 antibody is captured on the walls of the test well. Following this 30-minute incubation, the contents of the wells are removed and the wells are washed to remove any unbound Aflatoxin M1 and free Aflatoxin M1 antibody. After wash, 1X HRP-conjugated Antibody#2 is added for 30 minutes incubation. The wells are washed afterwards, and a clear substrate is then added to the wells and any bound enzyme conjugate causes the conversion to a blue color. Following a 15-minute incubation, the reaction is stopped and the amount of color in each well is read. The color of the unknown samples is compared to the color of the calibrators and the Aflatoxin M1 concentration of the samples is derived.
The HiPure Plasmid EF Mini Kit combine the power of HiPure technology with Magen’s innovative endotoxin removal technology to deliver high-quality plasmid DNA with low endotoxin levels foruse in eukaryotic transfection, and in vitro experiments. The HiPure plasmid endo-free system uses a specially formulated buffer that prevents endotoxin molecules from binding to the surface of the HiPure matrix. Endotoxin contamination lowers transfection efficiencies for endotoxin sensitive celllines. For gene therapy, endotoxin contamination should be of major concernsince endotoxins have the potential to cause fever, endotoxin shock syndrome, and interfere with in vitro transfection into immune cells.

Principle
The HiPure Plasmid procedure is based on alkaline lysis of bacterial cells followed by adsorption of DNA onto silica in the presence of high salt. The unique silica membrane used in the kit completely replaces glass or silica slurries for plasmid DNA minipreps. The procedure consists of 3 basic steps: Preparation and clearing of a bacterial lysate by alkaline method，then transfer the supernatant to column to bind DNA. After washing proteins and other impurities, nucleic acid was finally eluted with low-salt buffer (10mm Tris, pH9.0, 0.5mm EDTA).
Advantages
High purity – purified plasmid can be directly used in sequencing, enzyme digestion and PCR, etc.
Fast – silica gel column purification is much faster than ion exchange
High yield – up to 70μg plasmid can be binded in one column
Low endotoxin content – the obtained plasmid can be directly used in cell transfection and animal injection

Storage and Stability
The kit components can be stored dry at room temperature (15–25°C) and are stable for at least 18 months under these conditions. If any precipitates form in the buffers, warm at 37℃ to dissolve. After addition of RNase A，Buffer P1 is stable for 6 months when stored at 2–8°C.
