| PDGF-CC

PDGF-CC is a relatively new member of the PDGF family. PDGF-CC is abundantly expressed by different types of cells, such as tumor cells, endothelial cells (ECs),vascular smooth muscle cells (VSMCs), pericytes, fibroblasts, and macrophages. PDGF-CC binds to PDGFR-α and PDGFR-β, which are also expressed by many different cell types, including tumor cells, VSMCs, pericytes, and fibroblasts, all of which play important roles in angiogenesis. We and others have shown that PDGF-CC is a potent angiogenic factor.The angiogenic pathways induced by PDGF-CC appear to be largely VEGF-A-independent.Tumor-associated fibroblasts that are deficient of VEGF-A but with abundant PDGF-CC expression can promote tumor angiogenesis efficiently.
 

| 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	2.48	1.65	1.07	0.71	0.45	0.28	0.19	0.09
Corrected OD	2.39	1.56	0.98	0.62	0.36	0.19	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 PDGF-CC 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 PDGF-CC 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 (%)	85-95	88-96	90-110
	Average (%)	91	93	96
1 : 4	Range (%)	89-103	87-108	105-115
	Average (%)	94	98	108
