Northern blot analysis and expression of GRAP mRNA in tumor cell lines and normal human tissues.

Northern blots containing 2.5 μg human polyA⁺RNA extracted from cancer cell lines or normal human tissues (panels A and B, respectively). Blots were hybridized with GRAP sequences. RNA size markers are shown on the left. Panels A and B correspond to blots. Panels C and D correspond to β-actin controls.
