CORRECTION:
In the article by R.H. Christenson, H.
Vaidya, Y. Landt, R.S.Bauer, S.F. Green, F.A. Apple, et al.,
entitled "Standardizationof Creatine Kinase-MB (CK-MB) Mass Assays:
The Use of RecombinantCK-MB as a Reference Material" (Clin Chem
1999;45:1414–23),the first full sentence on page 1417 should read:
"Based onthis amino acid content, the absorbance of a 1 g/L CK-MB
solutionat 280 nm was estimated as 0.82, using a pathlength of 1 cm
12"rather than "Based on this amino acid content, the molar
absorptivityof CK-MB was estimated as 0.82 L/cm-mol (absorbance of 1
g/Lsolution of CK-MB at 280 nm using 1-cm pathlength) 12".
Theauthors regret any confusion this may have caused.
