Regional localization of a trophoblast antigen-related sequence and 16 other sequences to human chromosomes 6q using somatic cell hybrids.

Using a panel of 13 hybrid cell lines, we have regionally localized 22 markers to the long arm of chromosome 6. Revised or new locations are provided for 17 of the markers, and preliminary assignments to chromosome 6 of 11 loci are confirmed. The location of NT5, previously determined by antigen expression in hybrids, has been confirmed at 6q14-q15 by using a cDNA probe. Other DNA probes include one new anonymous sequence, designated D6S130, that maps to 6q12 and 4 VNTR probes that map to the proterminal band, 6q27. Probe CRI-L1065 also maps to 6q21, CRI-994 maps to 6q21-qter, and CRI-L322 maps to 6q14-15, information that may assist the merging of physical and genetic maps.

A fluorimetric assay of the phosphoribosylation of 6-mercaptopurine in human blood cells.

A new fluorimetric method to assay HGPRT (hypoxanthine-guanine phosphoribosyl transferase, EC 2.4.2.8) from human red cell lysates using 6MP (6-mercaptopurine) as substrate is described. This assay is compared with an existing spectrophotometric method using hypoxanthine as substrate. Precision, sensitivity limits and kinetic differences of these assays are reported.
