Immunoglobulin A only weakly. IgA exists in two isotypes, IgA1 and IgA2. They are both heavily glycosylated proteins. While IgA1 predominates in serum (~80%), IgA2 percentages are higher in secretions than in serum (~35% in secretions); the ratio of IgA1 and IgA2 secreting cells varies in the different lymphoid tissues of the human body: Both IgA1 and IgA2 have been found in external secretions like colostrum, maternal milk, tears and saliva, where IgA2 is more prominent than in the blood. Polysaccharide antigens tend to induce more IgA2 than protein antigens. Both IgA1 and IgA2 can be in membrane-bound form. ("see B-cell receptor")
A Guy Called Gerald single called "Wax On The Melt", a collaboration between a number of crews and Graham Massey and Martin Price together with whom he would later form 808 State. Their first album, "Newbuild", was released in 1988, but he soon left the group to concentrate on his solo work. The result of heading back into his bedroom studio was "Voodoo Ray", played first at the Hacienda in 1988 and then the underground clubs before entering the UK Singles Chart a year later. It was the first acid house track produced in the UK, and released on a small Merseyside independent label
