    摘要: The invention provides novel DNA and peptide sequences encoding a family of phospholipase A.sub.2 enzymes, with specific activities of approximately 20 .mu.mol/min/mg in the mixed micelle assay. These enzymes are useful in methods for detecting the anti-inflammatory potential of various chemical agents. The invention also details novel methods for determining such potential using the novel sequences, methods for making the novel peptides, and methods for developing new anti-inflammatory drugs.

    摘要: A method for detecting the presence of small mounts of contaminant DNA, present in an amount of at least about 0.1 picogram of DNA, in a protein product produced by recombinant DNA technology. The method comprises using oligonucleotides with sequences directed to those of repetitive host cell line DNA sequences, as primers in a PCR reaction. Also disclosed are kits for the detection of small amounts of contaminant DNA in a protein product.
