Inclusion body

[Scott Coutts]

You could try using 6M guanidinium hydrochoride. I use a buffer with the
following components:

	6M Guanidinium.HCl
	20mM Tris.HCl
	100mM NaCl
	5mM DTT

Clean up your pellet (I assume you have the inclusion bodies ready for
solubilisation), then very thoroughly resuspend it in the above buffer,
making sure there are no 'lumps' (vortex, at least). Leave it overnight
at four degrees celcius.

Hope that helps,
