Creatine Kinase MM Isoenzyme III, Recombinant, Human (CKMM)

The three isoenzymes (MM, MB, and BB) are found in muscle, cardiac and brain tissues. These recombinant proteins are ideal for calibrating diagnostic instruments and researching neuromuscular diseases. Creatine Kinases can be used for indications in many neuromuscular applications. These disorders include cardiac disease, mitochondrial disorders, inflammatory myopathies, myasthenia, polymyositis, McArdle's disease, NMJ disorders, muscular dystrophy, ALS, hypo and hyperthyroid disorders, central core disease, acid maltase deficiency, myoglobinuria, rhabdomyolysis, motor neuron diseases, rheumatic diseases, and other that create elevated or reduced levels of Creatine Kinases.\n\nRecombinant Human Creatine Kinase MM produced in Pichia pastoris is a glycosylated polypeptide chain having an identical amino acid sequence compared to the native enzyme, purified under non-denaturing conditions and reacts with polyclonal antibodies to MM Isoenzyme in ELISA.\n\nDimers and Aggregates: \nLess than 1% as determined by silver-stained SDS-PAGE gel analysis.\n\nBiological Activity: \nThe biological activity measured by the enzymatic activity of Creatine phosphokinase procedure No.45-UV, 1IU-1 umole creatine phosphate was 500IU/mg at 37 degrees C.\n\nEndotoxin: \nLess than 0.1ng/ug (IEU/ug) of Human CKMM.\n\nStorage and Stability:\nMay be stored at 4 degrees C for short-term only. For long-term storage, store at -20 degrees C. Aliquots are stable for at least 6 months at -20 degrees C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
