The structures of the classical A and M antigens of Brucella were recently shown to be hompolymers of 4,6-dideoxy-4-formamido-a-D-mannopyranose [102, 103]. The A antigen was an a-l,2-linked polymer, while the M antigen was also linear but was composed of a pentasaccharide repeating unit of four a-1,2- and one a-l,3-linked residues.

Precise quantitative work with the SRID test requires that the wells be cut repro-ducibly, and have vertical walls to produce distinct rings. To facilitate measurement, once the precipitin forms, the slide can be rinsed with PBS overnight to remove free Ab from the gel, then stained with a general protein stain such as Coo-massie Blue. With this staining technique, detection limits of 10-7 M antigen have been achieved. 

Microcrystalline cellulose (1 g) is washed with distilled water and oxidized in 40 ml 100 mM NaHCOs containing 60 mM NaI04 in the dark for 2 h at room temperature in a closed container. This activated matrix is quickly washed on a sintered glass filter with 100 mM sodium carbonate buffer, pH 9.0, to remove by-products. For conjugation, the cellulose is suspended in 40 ml of the pH 9 buffer containing 10 M antigen or antibody and stirred overnight at room temperature, followed by two additions (30 min... 

In Enterobacteriaceae, certain of those polysaccharides which comprise the M antigens have been found to carry some acetal substituents, such as carboxyethylidene, ethylidene, isopropylidene, or methylidene. Such groupings may be identified by injecting an aqueous hydrolyzate onto columns of Carbowax or OV-1.
