Troponin C, also known as TN-C or TnC, is a protein that resides in the troponin complex on actin thin filaments of striated muscle (cardiac, fast-twitch skeletal, or slow-twitch skeletal) and is responsible for binding calcium to activate muscle contraction.Troponin C is encoded by the TNNC1 gene for both cardiac and slow skeletal muscle.Mutations in this gene are associated with cardiomyopathy dilated type 1Z.In cardiac muscle, cTnC binds to cardiac troponin I (cTnI) and cardiac troponin T (cTnT), whereas cTnC binds to slow skeletal troponin I (ssTnI) and troponin T (ssTnT) in slow-twitch skeletal 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 (pg/mL)	4000	2000	1000	500	250	125	62.5	0
OD	2.22	1.56	0.92	0.63	0.42	0.25	0.18	0.08
Corrected OD	2.14	1.48	0.84	0.55	0.34	0.17	0.1	-

 

| Repeatability

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

| Recovery

The recovery of Human tnnc1 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)	84-100	96
Plasma(n=8)	95-105	102
Tissue Homogenates(n=8)	96-108	103

 

| Linearity

Samples were spiked with high concentrations of Human tnnc1 and diluted with Universal Diluent to produce samples with values within the range of the assay.

 

		Serum(n=4)	Plasma(n=4)	Tissue Homogenates(n=4)
1 : 2	Range (%)	84-95	88-96	90-110
	Average (%)	91	93	96
1 : 4	Range (%)	89-103	87-108	105-115
	Average (%)	94	98	108
