The international standard for atrial natriuretic factor. Calibration by an international collaborative study.
An ampouled preparation of human atrial natriuretic factor, ANF-(99-126), was evaluated by 23 laboratories in 10 countries for its suitability to serve as the international standard for ANF. The preparation was calibrated by radioimmunoassay, radioreceptor binding assay, and bioassay and was shown to have satisfactory stability and biological activity. Estimates of the ANF content of a set of s...

متن کاملInternational collaborative study to evaluate a recombinant L ferritin preparation as an International Standard.
A recombinant L ferritin preparation, lyophilized in ampoules and designated 94/572, was evaluated by 18 laboratories in 9 countries for its suitability as an International Standard (IS). The preparation was assayed in a wide range of in-house and commercial immunoassays against the 2nd IS for ferritin (of spleen origin; 80/578). The immunological reactivity of the recombinant material was simi...
متن کاملCollaborative study for the calibration of a new Italian HCV RNA reference preparation against the international standard.
We organised a collaborative study to calibrate a new Italian reference preparation for HCV RNA, the ISS 0102 reagent, to be used for plasma pools testing. This preparation will replace the previous one, the ISS 0498 reagent, as we are running short of it. The ISS 0102 reagent was obtained by appropriately diluting an HCV RNA-positive donation. Every participant in the collaborative study recei...
