GMC lysates from various groups were used for co-immunoprecipitation as described previously (Koshiba et al. 2004 (link), Zhang et al. 2009) (link). In brief, cell lysates were first cleared with 50% protein A-agarose (Santa Cruz Biotechnology) and were then incubated with rabbit polyclonal antibody against mfn2 protein (Thermo Scientific) for 1 h at 4°C, followed by incubation with protein A-agarose overnight at 4°C. The antigenantibody-protein A-agarose complex pellets were collected through centrifugation and washed with RIPA buffer. The bound proteins were separated using SDS-PAGE and were then transferred to PVDF membranes for Western blot analyses with anti-mfn2 (Thermo Scientific), anti-Ras (Santa Cruz Biotechnology) or non-specific IgG antibodies (Santa Cruz Biotechnology).

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
