Forwarded: grinding medium

[Jenny Davila-Aponte]

I'm a post-doc in Ken Keegstra's lab, where we study import of proteins
into chloroplasts.  The grinding buffer we use contains the following:
	50 mM HEPES-KOH, pH 7.3
	330 mM sorbitol
	0.1% bovine serum albumin, fraction V
	1 mM MgCl2
	1 mM MnCl2
	2 mM Na2EDTA

We don't normally include glutathione or isoascorbate, but if they're
added, we don't bother to adjust the pH after the addition.  

Hope this helps,
Jenny Davila-Aponte
