Novex tris glycine 4 20 precast gels

Manufactured by Thermo Fisher Scientific

Novex Tris-Glycine 4–20% precast gels are polyacrylamide gels used for protein separation and analysis in electrophoresis procedures. They have a gradient concentration of 4-20% acrylamide, which allows for the separation of a wide range of protein sizes. These gels are pre-cast, ready-to-use, and designed for use with Tris-Glycine buffer systems.

Samples were boiled in 2× SDS-PAGE loading buffer (78.0 mM Tris [pH 6.8], 4% SDS, 20% glycerol, 100 mM DTT, 0.2% bromophenol blue) and loaded on SDS-PAGE gels (fixed % between 10 and 15% acrylamide [37.5:1], Bio-Rad, or Novex Tris-Glycine 4–20% precast gels [Invitrogen]). Proteins were transferred onto PVDF (Immobilon), which were blocked in TBS-T containing 5% nonfat milk or BSA before primary antibodies were added overnight at 4 °C. After three TBS-T washes, membranes were incubated with HRP-conjugated secondary antibodies (Bio-Rad, 1:10,000) and developed with ECL reagents (Pierce). Antibodies used are in supplemental Table S2.

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.
