Detection Method
Method Type
Purpose Human NF-κB p50 Transcription Factor Activity Assay. This assay uses a dsDNA coated plate with canonical NF-κB binding sequences to semi-quantitatively detect active NF-κB in lysates or nuclear extracts. Only available in North America.
Sample Type Cell Lysate, Nuclear Extract
Analytical Method Semi-Quantitative
Detection Method Colorimetric
Specificity The olionucleotide/antibody pair provided in this kit recognizes human NF-κB p50 in whole lysates and nuclear extracts.
