Acrylamide

Manufactured by National Diagnostics
Sourced in United States

Acrylamide is a chemical compound used as a laboratory reagent. It is a colorless, odorless, crystalline solid that is soluble in water and other polar solvents. Acrylamide is commonly used in the preparation of polyacrylamide gels for electrophoresis, a technique used to separate and analyze biological macromolecules such as proteins and nucleic acids.

[γ–32P]-ATP was purchased from MP Biomedical (Irvine, CA, USA). Unlabeled deoxynucleoside triphosphate (dNTPs) (ultrapure) were obtained from Pharmacia. Unlabeled dNTPs (ultrapure) were obtained from Pharmacia. Magnesium acetate, magnesium chloride and Trizma base were from Sigma. Urea, acrylamide and bis-acrylamide were from National Diagnostics (Rochester, NY, USA). Oligonucleotides, including those containing 8-oxo-guanine, were synthesized by Operon Technologies (Alameda, CA, USA). All modified nucleotides including N6-MedATP, 6-Cl-PTP, 6-Cl-2APTP, O6-MedGTP, N2-MedGTP, 2-6-dATP, dITP and 8-oxo-dGTP were obtained from Trilink Biotechnologies (San Diego, CA, USA). All non-natural nucleotides including IndTP, 5-MeITP, 5-Et-ITP, 5-EyITP, 5-NITP, 4-NITP and 6-NITP were synthesized and purified as previously reported (23 (link)–26 (link)). All other materials were obtained from commercial sources and were of the highest available quality. Exonuclease-deficient bacteriophage T4 DNA polymerase (gp43exo (Asp-219 to Ala mutation)) was purified and quantified as previously described (27 (link)). Recombinant human polymerase delta (pol δ) and human polymerase eta (pol η) were purified as previously described (28 (link),29 (link)). All DNA polymerases used in this study were >97% pure as assessed by sodium dodecylsulphate-polyacrylamide denaturing gel electrophoresis.

Samples were separated on 7.5%, 10%, or 15% sodium dodecyl sulfate (SDS) polyacrylamide (PA) gels (acrylamide; National Diagnostics, Atlanta, GA; Cat #: EC-890) and transferred to nitrocellulose membranes (BioRad, Hercules, CA; Cat #: 162–0115) in 25 mM Tris, 192 mM glycine, and 20% methanol. After the transfer, the membrane was blocked in 4% milk for 1 hour at room temperature and then immunoblotted. Results were visualized with horseradish peroxidase-conjugated secondary antibodies (Jackson ImmunoResearch, West Grove, PA) and enhanced chemiluminescence (Pierce/Thermo Scientific, Waltham, MA).

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
