A cDNA clone for the complete coding sequence for alpha-1,3(6)-mannosylglycoprotein beta-1,6-N-acetylglucosaminyltransferase V (GlcNAc-T V, EC 2.4.1.155) was isolated and expressed in COS-7 cells. Degenerate oligonucleotide primers for polymerase chain reaction were synthesized based on the amino acid sequence of three tryptic peptides isolated from affinity-purified GlcNAc-T V. Polymerase chai...

A cDNA clone coding for the major house dust mite allergen Der p 1 was isolated from a lambda gt 11 library. Its sequence correlates with known amino acid sequences of Der p 1 and it produces a fusion protein which reacts with rabbit anti-Der p 1 antiserum.

We have isolated a human collagen alpha 1(I)-like gene from a cosmid library. The clone which contains 37kb of human DNA has been shown to contain this gene by DNA sequencing, hybrid arrest and hybrid selection assays and Northern blot hybridizations. The collagen gene sequence extends through most of the cloned DNA and must, therefore, be at least 35kb in length.

Generalization problems arise in many areas of software science: code clone detection, program reuse, partial evaluation, program synthesis, invariant generation, etc. Anti-unification is a technique used often to solve generalization problems. In this paper we describe an open-source library of some newly developed anti-unification algorithms in various theories: for firstand second-order unra...

A clone library of the partial formyltetrahydrofolate synthetase gene (fhs), a key enzyme in reductive acetogenesis, was constructed from the DNA of bovine rumen contents. Diverse sequences were recovered, the majority of which were clustered with the fhs of authentic acetogens. Low similarity values to known fhs were observed in all sequences, suggesting the presence of unknown acetogens.

The cDNA coding for dog thyrotropin (TSH) receptor was cloned from a dog thyroid library. The cloning procedure was based on the method described previously (Libert et al., 1989). The clone presented here was unambiguously identified as the thyrotropin receptor by expression in oocytes and culture cells (Parnentier et al., 1989).

In many meningiomas, alterations of chromosome 22 can be found, and the NF2 (neurofibromatosis type 2) gene, in particular, is of great interest as a putative gene involved in meningioma. Because the NF2 gene is not mutated in all meningiomas, additional genes may be involved. Instead of looking for alterations directly at the DNA level, we used the immune response of meningioma patients to ide...

A bacterial artificial chromosome (BAC) library for the A-genome of cotton has been constructed from the leaves of G. arboreum L cv. Jianglinzhongmian. It is used as elite A-genome germplasm resources in the present cotton breeding program and has been used to build a genetic reference map of cotton. The BAC library consists of 123,648 clones stored in 322 384-well plates. Statistical analysis ...

BACKGROUND The causative pathogens of healthcare-associated pneumonia (HCAP) remain controversial, and the use of conventional cultivation of sputum samples is occasionally inappropriate due to the potential for oral bacterial contamination. It is also sometimes difficult to determine whether methicillin-resistant Staphylococcus aureus (MRSA) is a true causative pathogen of HCAP. METHODS We e...

A group-specific PCR-based denaturing gradient gel electrophoresis (DGGE) method was developed and combined with group-specific clone library analysis to investigate the diversity of the Clostridium leptum subgroup in human feces. PCR products (length, 239 bp) were amplified using C. leptum cluster-specific primers and were well separated by DGGE. The DGGE patterns of fecal amplicons from 11 hu...
