Protein enzyme derivative.

摘要

The B subunit of creatine kinase has been made substantially free of albumin and substantially enzymatically inactive. Antibodies recognising the subunit can be raised by inoculating a host with a suitable immunogen and collecting serum or plasma from the host. The subunit may be labelled, e.g. with a radioisotope. The labelled subunit and antibodies may be packed separately in a diagnostic kit.
