Report prepared for laboratory personnel using Qiagen RNeasy kits. For safety data, consult Qiagen SDS for Buffer RPE (catalog numbers 1018013, 1018019).

Buffer RPE is a proprietary, mild washing buffer used in diverse QIAGEN nucleic acid purification kits to ensure high-purity RNA and DNA samples. It is most commonly associated with RNeasy , miRNeasy, and AllPrep procedures.

: Buffer RPE is typically supplied as a concentrate. Users must add 4 volumes of ethanol (96–100%) before the first use. For instance, a 55 ml concentrate is diluted to a larger final volume.

Buffer RPE serves two sequential purposes: Report prepared for laboratory personnel using Qiagen RNeasy

: It is a liquid with a characteristic odor and a pH of approximately 7.5 .

In a standard Qiagen protocol, Buffer RPE is added to the spin column and centrifuged to facilitate the washing of the silica membrane. Typically, two consecutive wash steps are performed using Buffer RPE to ensure optimal purification. It is most commonly associated with RNeasy ,

The isolation of high-quality plasmid DNA and RNA is fundamental to molecular biology, cloning, and transfection applications. Qiagen’s anion-exchange and silica-membrane technologies rely on a sequence of buffers to lyse cells, bind DNA, wash away impurities, and elute the final product. Buffer RPE (often noted in protocols alongside Buffers P1, P2, and P3) is the dedicated wash buffer used in the final stages of purification. Its formulation is optimized to prepare the nucleic acid for elution in a low-ionic-strength buffer or water, ensuring the sample is free of contaminants that inhibit enzymatic reactions.
