Arrow indicates the presence of an unspecific product. Although not desirable, this product did not interfere with the use of mix E in a microdeletion screening project. Occasionally, mix C was used without the primers for loci 4 and 5. In such cases, this mix is called mix undefined.</font></p> </td> </tr> <tr> <td> <p> </p> </td> <td> <p> <font color="#5247f1"><b>Fig. 2.</b> Mixtures F-I on a 2.5% agarose gel.</font></p> </td> </tr> </tbody> </table> <table> <tbody> <tr> <td> <p>  </p> <hr /> <font> </font> <p>  </p> </td> <td> <p>  </p> <hr /> <font> </font> <p>  </p> </td> </tr> <tr> <td> <p> <font color="#5247f1"><b>Fig. 3.</b> Multiplex PCR with mix J on four different genomic DNA templates, separated on an a denaturing, 6% polyacrylamide gel.

These primers amplify polymorphic loci, and alleles of different sizes can be observed. The shortest alleles of locus 6 and the longest alleles of locus 7 can, sometimes, overlap, making it difficult to assign precisely their origin.
