| CKM

Creatine kinase, muscle also known as MCK is a creatine kinaseencoded by the MCK gene. The protein encoded by this gene is a cytoplasmic enzyme involved in cellular energy homeostasis. In vivo, two muscle-type M-CK monomers are symmetrically arranged to form an active MM-CK enzyme. The encoded protein reversibly catalyzes the transfer of "energy-rich" phosphate between ATP and creatine and between phospho-creatine and ADP. Its functional entity is a MM-CK homodimer in striated (sarcomeric) skeletal and cardiac muscle.
 

| Typical data

As the OD values of the standard curve may vary according to the conditions of the actual assay performance (e.g. operator, pipetting technique, wash technique or temperature effects), the operator should establish a standard curve for each test. Typical standard curve and data are provided below for reference only.

 

Concentration (ng/mL)	100	50	25	12.5	6.25	3.12	1.56	0
OD	2.56	1.77	1.22	0.71	0.46	0.31	0.23	0.07
Corrected OD	2.49	1.7	1.15	0.64	0.39	0.24	0.16	-

 

| Repeatability

Intra-assay Precision (Precision within an assay)：CV% < 10%; Inter-assay Precision (Precision between assays)：CV% < 10%
 

| Recovery

The recovery of Human CKM spiked at three different levels in samples throughout the range of the assay was evaluated in various matrices.

 

Sample Type	Range(%)	Average Recovery(%)
Serum(n=8)	84-101	96
Plasma(n=8)	92-105	102
Cell Culture Supernates(n=8)	96-107	105

 

| Linearity

Samples were spiked with high concentrations of Human CKM and diluted with Universal Diluent to produce samples with values within the range of the assay.

 

		Serum(n=4)	Plasma(n=4)	Cell Culture Supernates(n=4)
1 : 2	Range (%)	84-95	88-96	90-110
	Average (%)	91	93	96
1 : 4	Range (%)	89-103	87-108	104-115
	Average (%)	94	98	108
