Redissolving RNA Pellet

[Gina Beck]

I am working with total RNA from Chondrocyte cells.  I am isolating the
RNA using TRizol Reagent and I am having a problem with the last step of
redissolving the RNA pellet.  These cells have been put in 1.2% alginate
and cultured for 5 days and then extracted out of the alginate using 55
uM of Na Citrate solution.  Then I add Trizol and continue with the
isolation.  Do you think there may be excess of proteoglycan material
that is making the pellet hard to redissolve?  any suggestions?
