Abstract
Peptide sequence tags are identified and used to produce a class of global antibodies, which recognize all members of a particular protein family with uniform specificity, regardless of the species of origin. The tags are used to create antibodies to the major proteins of photosynthesis, and carbon and nitrogen metabolism. The antibodies have a range of applications as diagnostic detection reagents for major environmental processes.
Claims2
A method for detecting the presence of a PsbA protein (photosynthesis II protein A) in a sample comprising the steps of:
- (a) identifying and obtaining a peptide sequence tag conserved for the PabA protein, and exclusive to the PsbA protein wherein said peptide sequence tag is SEQ ID NO:
- 1, SEQ ID NO:14 or SEQ ID NO:15 ;
- (b) utilizing the tag to elicit the production of antibodies;
- and
- (c) using the antibodies to measure the concentration of PsbA protein in a sample.
