Transcription Factor Binding Assay

Check if the same lab product or an alternative is used in the 5 most similar protocols
Assay was performed as recommended by the manufacturer of Promoter-Binding TF Profiling Plate Array I (Signosis). Briefly, nuclear extract was isolated from 5 9 10 6 HD11 cells, and the protein content was estimated. The reaction mixture, including 15 ll of TF binding buffer, 3 ll of probes, 10 lg of nuclear extract and 4 ll of the NLRC5 promoter fragment or no DNA, was incubated at room temperature for 30 min to allow for formation of the TF-DNA complex. Unbound probes were separated from the complex, and bound probes were eluted and then hybridized to the plate and incubated overnight at 42 °C. Bound probes were detected using a HRP-streptavidin conjugate incubated with the chemiluminescent substrate. Finally, chemiluminescence was measured.

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.
