Fig 3. Flag® Immunoprecipitation assays confirming an interaction between LRP/LR and hTERT.

Fig 3

Pull down assays were used to detect LRP::FLAG as well as any associated proteins bound to the anti-M2 flag beads. A loading control of crude HEK293 lysate was incorporated to ensure the validity of the blots. Panel C indicates the positive and negative controls, where the Bound protein shows the detection of the BAP fusion protein (50 kDa) to the anti-FLAG beads. Panel B indicates that the LRP::FLAG protein was only present in the HEK293 transfected samples, where FLAG was detected on the anti-FLAG beads (Bound protein). Panel A illustrates the detection of a ±140 kDa band (Bound protein) showing a pull down of hTERT for the HEK293 transfected cell line, whereas no signal was detected for the non-transfected HEK293 cell line.
