| Comments： | Restriction digests of the clone give the following sizes (kb): BamHI--7.4; EcoRI--4.4, 3.0; HindIII--4.4, 3.0; PstI--5.0, 0.96, 0.36, 0.24; HincII--4.0, 3.4. To resolve some of the TaqI alleles with similar fragment sizes, the depositor suggests using a 0.9% agarose gel and allowing bromphenol blue migration of 15 cm. The St14 sequence family appears to be dispersed over a 570 - 600 kb region of Xq28. The TaqI B2 allele (4.1 + 1.4) is almost exclusively associated with the 3.4 kb allele from the VNTR polymorphism. This probe also detects polymorphisms with MspI, DdeI, BglI, and Tth111I. St14-1 detects genomic fragments of the following approximate sizes (kb): BamHI--3.6; HindIII--10.0; TaqI--3.9; EcoRI--10.0. |
