摘要:
A synthetic or recombinant polypeptide displaying the antigenicity of all or an antigenic fragment of the H4 or H11 polypeptides of Toxoplasma gondii, and recombinant DNA molecules, vectors and host cells for the expression thereof. Use of the polypeptide in vaccine compositions and in diagnostic immunoassays is also disclosed.
摘要:
A pre-determined concentration of stabilized, maturation-arrested porcine reticulocytes in a red blood cell base, useful as a reticulocyte control composition. The composition can be provided in the form of a concentrated reticulocyte composition, to be diluted to a desired final reticulocyte concentration at the time of use. The composition can also be provided in the form of a diluted, ready-to-use control composition. Also included is a method of preparing such a composition, the method involving sequential steps of forming and sedimenting Rouleaux bodies.
