| PC Ⅲ

Procollagen III (PCIII) is a kind of procollagen. Procollagen is the precursor of protocollagen and is the form before it is secreted into the extracellular system. Procollagen is formed by spiraling three proα chains, each with an N-terminal propeptide of 15 amino acid residues and a C-terminal propeptide of 25 amino acid residues.
 

| 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)	160	80	40	20	10	5	2.5	0
OD	2.47	1.73	1.04	0.57	0.36	0.22	0.17	0.09
Corrected OD	2.38	1.64	0.95	0.48	0.27	0.13	0.08	-

 

| Repeatability

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

| Recovery

The recovery of Rat PC Ⅲ 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 Rat PC Ⅲ 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	105-115
	Average (%)	94	98	108
