| THBS1

Thrombospondin 1, abbreviated as THBS1, is a protein encoded by the THBS1 gene. THBS1 is a subunit of a disulfide-linked homotrimeric protein. The thrombospondin-1 protein is a member of the thrombospondin family. Both positive and negative modulation of endothelial cell adhesion, motility, and growth have been attributed to TSP1. It also interacts with numerous proteases involved in angiogenesis, including plasminogen, urokinase, matrix metalloproteinase, thrombin, cathepsin, and elastase.
 

| 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)	50	25	12.5	6.25	3.12	1.56	0.78	0
OD	2.08	1.31	0.75	0.5	0.33	0.25	0.21	0.09
Corrected OD	1.99	1.22	0.66	0.41	0.24	0.16	0.12	-

 

| Repeatability

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

| Recovery

The recovery of Mouse THBS1 spiked at three different levels in samples throughout the range of the assay was evaluated in various matrices.

 

Sample Type	Range(%)	Average Recovery(%)
Plasma(n=8)	92-106	102
Tissue Homogenates(n=8)	96-108	105

 

| Linearity

Samples were spiked with high concentrations of Mouse THBS1 and diluted with Universal Diluent to produce samples with values within the range of the assay.

 

		Plasma(n=4)	Tissue Homogenates(n=4)
1 : 2	Range (%)	88-96	90-110
	Average (%)	93	95
1 : 4	Range (%)	87-110	105-115
	Average (%)	96	108
