- Standardization for enzymes in Japan are successful enough to converge within approximately 3% of CVs between laboratories, which is owing to the establishment of traceability chain with the JCCLS-CRM, a certified reference standard for enzymes, being composed of human recombinant enzymes.
- Reference measurement procedures (RMP) of enzymes in Japan (JSCC consensus??? method) are not always the same with IFCC RMP. ?Catalytic activities of 7 kinds of enzymes on the JCCLS CRM were measured by IFCC RMP in an accredited laboratory and compared with those of JSCC method (in detail, see PDF A and PDF B).
- We received Rerence Material Producer Accreditation Certificate on March 29, 2013, and the JCCLS-CRM is produced under this certificate. This certificate is based on ISO guide 34:2009, and ISO 17025 regarding assignment of property values (see PDF C).
