+27.	Resuspend the beads with 500µl HKM (0.1% Tween-20) and transfer to a new tube, again wash old tube carefully with 500µl and add to new tube 
+28.	spin again and wash two more times with 750µl HKM and 0.1% Tween
+29.	spin down, remove the supernatant carefully, add 100 µl 2x SDS-buffer without DTT
+30.	boil all samples 1 min at 95°C
+31.	Take the eluate from the beads with a 100 µl Hamilton pipette (ensure good washing of the pipet, SDS running buffer, H2O, H2O)
+32.	Add 50mM DTT and boil again 5 min to cleave the crosslinker 
+33.	Take 10 µL for western, freeze the rest at -20°C
