TY - JOUR TI - Cell-free Generation of COPII-coated Procollagen I Carriers AU - Yuan, Lin AU - Baba, Satoshi AU - Bajaj, Kanika AU - Schekman, Randy VL - 7 IS - 22 PY - 2017 DA - 2017/11/20 SP - e2450 C1 - Bio-protocol 2017;7:e2450 DO - 10.21769/BioProtoc.2450 UR - https://doi.org/10.21769/BioProtoc.2450 AB - The aim of this protocol is to generate COPII-coated procollagen I (PC1) carriers in a cell-free reaction. The COPII-coated PC1 carriers were reconstituted from donor membrane, cytosol, purified recombinant COPII proteins, and nucleotides. This protocol describes the preparation of donor membrane and cytosol, the assembly of the reaction, and the isolation and detection of reconstituted COPII-coated carriers. This cell-free reaction can be used to test conditions that stimulate or suppress the packaging of PC1 into COPII-coated carriers.
