| DBP

D site of albumin promoter (albumin D-box) binding protein, also known as DBP, is a protein which is encoded by the DBP gene.DBP is a member of the PAR bZIP (Proline and Acidic amino acid-Rich basic leucine ZIPper) transcription factor family.DBP binds to an upstream promoter in the insulin gene.DBP was shown to follow a stringent circadian rhythm;both the levels of protein and mRNA are almost non-detectable in the morning, but reach their maximum level in the evening.
 

| 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)	20	10	5	2.5	1.25	0.62	0.31	0
OD	2.15	1.67	1.21	0.85	0.52	0.34	0.21	0.12
Corrected OD	2.03	1.57	1.02	0.73	0.4	0.22	0.13	-

 

| Repeatability

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

| Recovery

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

 

Sample Type	Range(%)	Average Recovery(%)
Tissue Homogenates(n=8)	84-101	96

 

| Linearity

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

 

		Tissue Homogenates(n=4)
1 : 2	Range (%)	84-95
	Average (%)	91
1 : 4	Range (%)	89-103
	Average (%)	98
