| BMP-2

Bone morphogenetic protein 2 or BMP-2 belongs to the TGF-β superfamily of proteins.BMP-2 like other bone morphogenetic proteins,plays an important role in the development of bone and cartilage. It is involved in the hedgehog pathway, TGF beta signaling pathway, and in cytokine-cytokine receptor interaction. It is also involved in cardiac cell differentiation and epithelial to mesenchymal transition.Like many other proteins from the BMP family, BMP-2 has been demonstrated to potently induce osteoblast differentiation in a variety of cell types.BMP-2 may be involved in white adipogenesis[8][9] and may have metabolic effects.
 

| 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	2.23	1.42	0.83	0.5	0.31	0.23	0.18	0.08
Corrected OD	2.15	1.34	0.75	0.42	0.23	0.15	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 BMP-2 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 BMP-2 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 (%)	90	93	96
1 : 4	Range (%)	89-103	87-108	105-115
	Average (%)	94	98	108
