1. Introduction

Nucleic acid hybridization is a process in which complementary single strands of nucleic acids combine to achieve a stable double-stranded nucleic acid molecule. This action has been used to establish a molecular or genetic relatedness among organisms and to characterize their genomes. Furthermore, this technique is one of several diagnostic tools useful for detecting a wide variety of conditions. Since the determination of the basic principles of duplex formation and stability in the 1950s, many variations of the hybridization techniques have been developed. Southern first transferred DNA fragments from agarose, after electrophoretic separation, onto nitrocellulose (1). The technique is known as Southern blotting. Alwine et al (2) described shortly afterward a similar Northern blotting technique in which separated RNA strands are transferred from an agarose gel to a suitable solid support. A logical extension of these blotting techniques has been the dot or slot blot...
