Creatine Kinase MB Isoenzyme Type-II, CKMBITII, CKMBI, CKMB.
CK-MB Type II possesses the naturally occurring carboxy-terminal amino acid lysine.
This occurs during a myocardial infarct (MI or heart attack) when CK-MB Type II is released from damaged heart muscle, and the C-terminal lysine is cleaved in the blood stream, thus creating CK-MB Type I. This difference can be exploited in diagnosis of an MI.
CKMBITII Human Recombinant 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 MB Isoenzyme in ELISA.
The CKMBITII is purified by proprietary chromatographic techniques.
Pichia Pastoris
Sterile Filtered colourless liquid formulation.
Each mg of protein contains 20mM Tris-HCl, pH-6.8, 1mM EDTA and 1mM DTT.
CKMBITII although stable at 15°C for 7 days, should be stored desiccated below -18°C.
Please prevent freeze-thaw cycles.
Greater than 95.0% as determined by:
(a) Analysis by RP-HPLC.
(b) Analysis by SDS-PAGE.
The 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.
