mRNA extraction kit

[Y.R. Boisclair]

I want to obtain very good quality mRNA from cells.  I will start from
small amounts of total RNA (30-100 microgram).  I am debating between the
micro mRNA purification kit from pharmacia and the Polytract mRNA isolation
system from Promega.  Which one should I use for good yield and quality ? I
would like to hear from anybody who has used either system.
