NF-κB Activation Monitoring in SUM159

Check if the same lab product or an alternative is used in the 5 most similar protocols
Lentiviral particles containing luciferase reporter construct driven by NF-κB (system biosciences) were obtained and transfected into SUM159 cell line. Briefly, 4 copies of NF-κB TRE sequences “GGGACTTTCC” were inserted upstream of minimal essential CMV (mCMV) promoter which drives GFP-T2A-luciferase. Polyprotein is cleaved at the T2A site to give rise to GFP and Luciferase. Cell lines were plated at a density of 3000 cells per well in a clear bottom, white 96-well plate and treated with the indicated concentration with sulforaphane. Two hours following incubation with sulforaphane, TNF-α concentration in media was brought to 50 ng/ml. After 6 h Luciferase activity was measured according to manufacturer’s instructions using oneGlo assay (Promega) on Bio-Tek Synergy 2 plate reader.

NF-κB Luciferase Assay in BT474 Cells

Check if the same lab product or an alternative is used in the 5 most similar protocols
Lentiviral particles containing luciferase reporter construct driven by NF-κB (System Biosciences) were obtained and transfected into BT474 and BT474 PTEN LTT cells. Two hours following incubation with SF, TNF-α concentration in media was brought to 50 ng/ml. After 6 hr Luciferase activity was measured according to manufacturer’s instructions with oneGlo reagent (promega) on Synergy 2 plate reader (BioTek).

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.
