doi: 10.1038/s41598-017-09518-1
Figure Lengend Snippet: High-level expression and purification of TRAIL-Trimer fusion protein. ( a ) 10% SDS-PAGE analysis of TRAIL-Trimer expression from a fed-batch serum-free cell culture in the bioreactor. 10 µL of cell-free conditioned medium from Day 6 to Day 13 were analyzed under non-reducing condition followed by Coomassie Blue staining. ( b ) Bioassay analysis of TRAIL-Trimer production in conditioned medium from Day 5 to Day 13. ( c ) SDS-PAGE and western blot analysis of purified TRAIL-Trimer under either non-reducing or reducing conditions. 2 µg of purified protein was analyzed by a 10% SDS-PAGE and stained with Coomassie Blue. 0.2 µg of purified protein was analyzed by western blot using monoclonal antibody against TRAIL-domain and Trimer-domain, respectively.
Article Snippet: Bioactivity of purified TRAIL-Trimer, TRAIL-Fc and native TRAIL was evaluated using a Real-Time Cell Analysis (RTCA) iCELLigence system (ACEA Biosciences, San Diego, CA, USA) based on electrical impedance measurement which is a label-free approach for cell-based assays .
