LANCE Ultra total NFκB kits are designed for the detection of NFκB (both phosphorylated and non-phosphorylated) in cell lysates using a simple, homogeneous LANCE Ultra TR-FRET assay (no wash steps). This assay is compatible with both adherent and suspension cells, and is intended to be used as a control or normalization assay in conjunction with the LANCE phospho-NFκB assay.
