Constitutive probes (again?)

	I am currently studying gene expression in Arabidopsis roots, 
stems, leaves, flowers and siliques and am looking for a constitutive 
probe for my northerns. I have previously tried an 18S ribosomal probe 
which worked fine but I found I could not strip and reuse the filters 
afterwrds. I then tried Actin (AAc1, Nairn et al., (1988) Gene, 65. 
p247-257) but this seems to be more highly expressed in flowers and 
perhaps less in leaves i.e. its not constitutive. 
	Does anyone who has done similar studies in the past have any 
suggestions as to a better probe and if so where I could get it from. 
Hope some one can help. My e-mail is jrh2 at st-andrews.ac.uk   
		Thanks for any advice,
