A rapid and simple one step method for isolation of poly(A)+ RNA from cells in monolayer.

A simple method was developed to isolate low abundance hormone receptor poly(A)+ RNA from cells in tissue culture. Adherent cells in tissue culture plates were directly released with proteinase K and solubilized in SDS. Oligo(dT) cellulose was directly added to the lysate to obtain poly(A)+ RNA. Yields and purity of the poly(A)+ RNA were comparable to other more lengthy methods. IGF-I receptor and insulin receptor mRNA could be detected on Northern blot without any degradation.
