ProLabel systemÀÇ Æ¯Â¡

Figure 1. The ProLabel Screening Kit allows you to quantitatively measure the level of any recombinant protein. The ProLabel tag and Enzyme Acceptor(EA) combine to form an active enzyme that cleaves the chemiluminescent substrate; the resulting signal can be detected with any standard luminometer.


Figure 2. Use ProLabel to quantify protein coimmunoprecipitation. Protein complexes formed between SV40 T and p53 (which strongly interact), and SV40 T and lamin (which do not specifically interact) were analyzed by immunoprecipitation. In both instances, SV40 T was tagged with ProLabel, while p53 and lamin were each fused to AcGFP1. The fusion proteins were coexpressed in HEK 293 cells and then complexes were immunoprecipitated from cell lysates using an anti-AcGFP1 antibody. Coimmunoprecipitation was indicated by increased chemiluminescence, as measured by our ProLabel Chemiluminescent Detection Kit. SV40 T = SV40 large T antigen. Lam = lamin. (1, 3)


Figure 3. ProLabel assays allow you to measure protein knockdown. HEK 293 cells were cotransfected with individual shRNA expression cassettes (generated with our Knockout RNAi Clone & Confirm Kits) and their respective target protein-ProLabel constructs. Knockdown efficiency was determined using the ProLabel Chemiluminescent Detection Kit (1).
