| TNNI1

Troponin I Type 1, Slow Skeletal (TNNI1) is a protein encoded by the TNNI1 gene.It is a tissue-specific subtype of troponin I, which in turn is a part of the troponin complex.The function of TnI is to control striated muscle contraction and relaxation. Troponin I interacts with all major regulatory proteins in the sarcomeric thin filaments of cardiac and skeletal muscles: troponin C, troponin T, tropomyosin and actin.When cytosolic Ca2+ is low, TnI binds the thin filament to block the myosin binding sites on actin.
 

| 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)	3000	1500	750	375	187.5	93.75	46.87	0
OD	2.36	1.56	1.04	0.65	0.46	0.34	0.29	0.1
Corrected OD	2.26	1.46	0.94	0.55	0.36	0.24	0.19	-

 

| Repeatability

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

| Recovery

The recovery of Human TNNI1 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)	96-108	105

 

| Linearity

Samples were spiked with high concentrations of Human TNNI1 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 (%)	89-102	87-108	105-115
	Average (%)	94	98	108
