Abstract
An isolated and purified non-denatured transferrin receptor protein of a Moraxella strain, particularly,has an apparent molecular mass of about 80 to about 90 kDa, as determined by SDS-PAGE. The transferrin receptor protein or a fragment analog thereof is useful in diagnostic applications and immunogenic compositions, particularly for in vivo administration to a host to confer protection against disease caused by a strain of Moraxella. The transferrin receptor protein is isolated from strains of,by a procedure including extraction of agent soluble proteins of a cell mass produced by cultivating the strain under iron-starved conditions. The transferrin receptor protein is selectively solubilized from the extracted cell mass and purified.
