Reducing agent and detergent compatible protein assay rc dc assay

Manufactured by Bio-Rad
Sourced in United States

The Reducing Agent and Detergent compatible protein Assay (RC/DC) is a colorimetric assay that can measure protein concentration in the presence of reducing agents and detergents. It is designed to be compatible with samples containing compounds that interfere with other protein assays.

Cells were collected as described above. Protein concentrations were measured using Reducing Agent and Detergent compatible protein Assay (RC/DC) assay (Bio-Rad, Hercules, CA, USA, 500–0119). A total of 40 μg of protein was loaded and ran on an SDS-PAGE gel, transferred to a PVDF membrane, and blocked in 5% milk in Tris-buffered saline (TBS). Membranes were probed overnight for primary antibodies specific to puromycin (Jackson ImmunoResearch, 115-035-206) and ubiquitin (Cell Signaling, 3933). Antibodies were diluted by using Odyssey Blocking Buffer TBS (LI-COR, 927-50000). LI-COR secondary antibodies conjugated with InfraRed were used according to the manufacturer’s protocol (LI-COR, 925-32211). Membranes were imaged on LI-COR Odyssey FC using IR detection. Entire lanes were normalized to the 45 kDa actin band of Ponceau S strain as a loading control. Ponceau S band densities did not differ between any groups. This was used was as a relative measure of the amount of actively translated proteins in the polysome prior to harvest of cells.

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.
