Purification, characterization, and seroactivity of a 20-kilodalton Brucella protein antigen.

M S Zygmunt1, F B Gilbert, G Dubray.   

Abstract

An internal protein was purified from cell extracts of Brucella melitensis B115 by a combination of preparative isoelectric focusing and high-performance size exclusion chromatography. The protein has an apparent molecular mass of 230 kDa as determined by size exclusion chromatography. The protein was resolved to a single band of 20 kDa after sodium dodecyl sulfate-polyacrylamide gel electrophoresis. The native protein had an isoelectric point of 4.9. The N-terminal sequence of the 20-kDa protein was determined. The 20-kDa protein has been identified as antigen A-2 with a previously described anti-antigen A-2 serum (B. Stemshorn, K. Nielsen, and B. Samagh, Can. J. Comp. Med. 45:77-81, 1981). Antigen A-2 reacted with sera from infected sheep in immunoblotting and may be useful in developing diagnostic tests for brucellosis.
