We report the isolation and sequence of partial cDNA clones coding for human catalase. These clones were recovered from a human fibroblast cDNA library by screening with mixtures of oligonucleotide probes deduced from the amino acid sequence of human erythrocyte catalase. A comparison of their nucleotide sequence with the known protein sequence and mapping(More)
Techniques for three-dimensional (3D) light microsocpy throughout the volume of the specimen, not just a stereo image. of a wide variety of biological specimens are rapidly maturing. The Three-dimensional imaging is especially valuable when the specinext advances are to improve image contrast, make image resolution men is substantially thicker than the(More)
A radioisotopic assay is described to distinguish between Chinese hamster and human steroid sulfatase activity in extracts prepared from hamsterxhuman somatic cell hybrids. This assay is based on different pH optima and provides a sensitive and unambiguous biochemical marker for the short arm of the human X chromosome and as well as for otherwise(More)
We have used a cDNA clone for human phosphoglycerate kinase (PGK) to examine the chromosomal localization of three members of the human PGK gene family. Using somatic cell hybrids segregating portions of several X-autosome translocations as well as a clone panel of hybrids segregating radiation-induced fragments of the human X chromosome, we assign a PGK(More)
