Abstract
Recombinant asparaginyl tRNA synthetase from human filarial parasite Brugia malayi. The enzyme is used in an assay for inhibitors of the synthetase and can be used as an antigen for producing antibody inhibitors of the disease, either monoclonal or polyclonal. The antibodies can be used to detect the synthetase and related enzymes. In particular, the synthetase can be used to produce an antibody to be used for detecting filarial nematodes. The synthetase can be used to produce adenylated nucleosides.
Claims2
An assay for detection of filariasis in an animal which comprises:
- (a) providing a biological sample from the animal suspected of containing filarial nematodes expressing asparaginyl-tRNA synthetase;
- (b) contacting the biological sample with an antibody to a recombinant DNA derived full length purified and enzymatically active asparaginyl-tRNA synthetase of Brugia malayi so that the antibody binds to the asparaginyl-tRNA synthetase in the sample;
- (c) detecting asparaginyl-tRNA synthetase in the sample bound to the antibody;
- and
- (d) correlating the antibody bound to the asparaginyl t-RNA synthetase to the filariasis.
