(noun)

Any of a range of cross-linked polymers of acrylamide; used to form soft gels.

Examples of polyacrylamide in the following topics:

  • Primer Extension Analysis

    • By running the product on a polyacrylamide gel, it is possible to determine the transcriptional start site, as the length of the sequence on the gel represents the distance from the start site to the radiolabelled primer.

  • Immunoblot Procedures

    • Proteins are generally separated by size using sodium dodecyl sulfate (SDS) polyacrylamide gel electrophoresis.

  • DNA Sequencing Based on Sanger Dideoxynucleotides

    • This is frequently performed using a denaturing polyacrylamide-urea gel with each of the four reactions run in one of four individual lanes (lanes A, T, G, C).

  • DNA Mobility Shifts

    • A mobility shift assay is electrophoretic separation of a protein-DNA or protein-RNA mixture on a polyacrylamide or agarose gel for a short period.
