✦ Synopsis

Three homodimeric creatine kinase isozymes (A*, BP, and C,) of the green sunfish (Lepomis cyanellus)

were purified by a combination of affinity chromatography, gel filtration, and preparative starch gel electrophoresis. The final preparations were isozymically pure and were used to elicit antibodies in rabbits. The use of the group-specific adsorbant Blue Sepharose CL-6B (Pharmacia) and specific elution conditions for creatine kinase facilitated purification. Fish creatine kinase isozymes are sensitive to denaturation and cannot be readily purified by procedures routinely used for mammalian creatine kinase isozymes.
