Abstract
This protocol describes a common procedure to perform co-immunoprecipitation
Co-immunoprecipitation
Co-immunoprecipitation
1h 10m
1h 10m
Media fractions were collected and centrifuged at 1000×g for 00:10:00
10m
The supernatant fractions were collected and concentrated (20-fold) using a 10 kDa Amicon filter.
Concentrated media fractions (1 ml) were incubated with 20 μl of anti-FLAG M2 affinity gel for 01:00:00 at 4 °C
1h
After washing 5 times with lysis buffer , SDS-PAGE sample loading buffer was added to the beads (twice the beads volume) and samples were processed for SDS-PAGE and immunoblot.
