|DNA Dot Blot||1:1000|
Supplied in 10 mM sodium HEPES (pH 7.5), 150 mM NaCl, 100 µg/ml BSA, 50% glycerol and less than 0.02% sodium azide. Store at –20°C. Do not aliquot the antibody.
IMPORTANT: This protocol employs an atypical fixation and denaturation strategy with which only certain targets are compatible. Where appropriate, this protocol will be linked to its validated antibody under the Product Information banner on the product-specific webpage.
NOTE: Prepare solutions with reverse osmosis deionized (RODI) or equivalently purified water.
NOTE: All subsequent incubations should be carried out at room temperature (20-25°C) unless noted otherwise.
Rinse three times in 1X PBS for 5 min each.
NOTE: If using a fluorochrome-conjugated primary antibody, then skip to Section C, Step 8.
Counterstain as appropriate.
NOTE: When including fluorescent cellular dyes in your experiment (DNA dyes, etc.), please refer to the dye product page for its recommended protocol. View our listing of cellular dyes validated for use in immunofluorescence.

Protocol Id: 865
Note: This protocol is written for spotting fragmented, purified genomic DNA (titration of 1000 ng, 500 ng, 250 ng, 125 ng, 62.5 ng, 31.25 ng, and 15.625 ng) onto a positively charged nylon membrane using a 96-well dot blotting apparatus. Depending on the source and type of DNA, more or less DNA may be required for detection with the antibody.
• Purify genomic DNA using a genomic DNA purification protocol or kit and sonicate
genomic DNA to generate fragments between 200 and 500 bp. DNA fragment size
can be analyzed by gel electrophoresis on a 1% agarose gel with a 100 bp DNA
• Cut a piece of nylon membrane to the size of the dot blot manifold.
• Wet nylon membrane with 10x SSC Buffer.
• Dry membrane by placing it in 96-well dot blot apparatus and applying vacuum.
NOTE: Due to the kinetics of the detection reaction, signal is most intense immediately following incubation and declines over the following 2 hr
