A collaborative study of a preparation of normal human serum for use as a reference in the assay of beta 2 microglobulin.
A biological standard for beta 2 microglobulin (beta 2m) determination has been prepared from pooled human serum by sampling and freeze-drying. A preliminary study of parallelism between the dose-response curves of the preparation and pure beta 2m or biological fluids was made with four different methods of assay and gave satisfactory results. In a collaborative study in five laboratories in five countries using a common method of assay, evidence was obtained that the preparation coded 80-12-3200 was suitable to serve as a standard for the assay of beta 2 microglobulin. Criteria included the constancy of the amount of material per vial and the stability of the freeze-dried product. The technique used for beta 2m determination was a radioimmunoassay.
