ELISA Kit PrincipleThe test principle applied in this kit is Sandwich enzyme immunoassay. The microtiter plate provided in this kit has been pre-coated with an antibody specific to Creatine Kinase, Muscle (CKM). Standards or samples are then added to the appropriate microtiter plate wells with a biotin-conjugated antibody specific to Creatine Kinase, Muscle (CKM). Next, Avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. After TMB substrate solution is added, only those wells that contain Creatine Kinase, Muscle (CKM), biotin-conjugated antibody and enzyme-conjugated Avidin will exhibit a change in color. The enzyme-substrate reaction is terminated by the addition of sulphuric acid solution and the color change is measured spectrophotometrically at a wavelength of 450nm +/- 10nm. The concentration of Creatine Kinase, Muscle (CKM) in the samples is then determined by comparing the O.D. of the samples to the standard curve.

ELISA Kit ReproducibilityIntra-assay Precision (Precision within an assay): 3 samples with low, middle and high level Creatine Kinase, Muscle (CKM) were tested 20 times on one plate, respectively. Inter-assay Precision (Precision between assays): 3 samples with low, middle and high level Creatine Kinase, Muscle (CKM) were tested on 3 different plates, 8 replicates in each plate.

Gene SymbolCKM
Gene Full Namecreatine kinase, M-type
Alias SymbolsCPK-M;creatine kinase M chain;creatine kinase M-type;creatine kinase, muscle;creatine phosphokinase M-type;M-CK;muscle creatine kinase.
NCBI Gene Id100009056
Protein NameCreatine kinase M-type
Description of TargetReversibly catalyzes the transfer of phosphate between ATP and various phosphogens (e.g. creatine phosphate). 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.
