  • The certification of the catalytic concentration of alanine aminotransferase (ALT) (E.C. from pig heart in a reconstituted lyophilized material CRM 426


The report describes the work carried out for certification of the catalytic concentration of alanine aminotransferase (L-alanine: 2-oxoglutarate aminotransferase, EC (ALT) in a lyophilised solution of partially purified ALT from pig heart dissolved in a bovine serum albumin matrix. The preparation has been shown to be homogeneous, and the loss of activity on storage at -20 C is predicted to be less than 0.01% per annum on the basis of accelerated degradation studies. The catalytic concentration of ALT in samples of the reconstituted material is certified to be 129 U/l or 2.14 microkat/l reconstituted solution according to the IFCC recommended method at 30 C.
