Our Abpromise guarantee covers the use of ab73650 in the following tested applications.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

  • Biological activityThe biological activity measured by the enzymatic activity of Creatine phosphokinase procedure No.45-UV, 1IU-1 µmole creatine phosphate was 892 IU/mg at 37 degrees celsius.
  • Applications



  • Purity> 95 % by SDS-PAGE.
    ab73650 is purified by proprietary chromatographic techniques under non-denaturing conditions. Purity is greater than 95.0% as determined by RP-HPLC and SDS-PAGE.
  • FormLiquid
  • Additional Notes

    Creatine Kinase MB, Type II, has a naturally occurring carboxy-terminal amino acid lysine. During a myocardial infarction (MI) Creatine Kinase MB Type II is released from damaged heart muscle, and the C-terminal lysine is cleaved in the blood stream, thus creating Creatine Kinase Type I.

  • RelevanceCreatine Kinase MB consists of a dimer of nonidentical chains. With MM being the major form in skeletal muscle and myocardium, MB existing in myocardium, and BB existing in many tissues, especially brain. Creatine Kinase MB reversibly catalyses the transfer of phosphate between ATP and various phosphogens. The creatine kinase isoenzymes play a central role in energy transduction in tissues with large fluctuating energy demands such as skeletal muscle, heart, brain and spermatozoa.

Product Wall

Thank you for contacting us.

The protein ab73649 is Creatine Kinase MB Isoenzyme Type-I and protein ab73650 is Creatine Kinase MB, type 2. Theoratically both will work; customer can buy any of these.

I hope this information is helpful...

Thank you for your enquiries and your interest.

Currently, we only have two antibodies (ab19603 and ab110655) which have been tested for sELISA - and only ab19603 is monoclonal.

Full length proteins are the followings: ab73649 and 7...
