| RBBP7

Histone-binding protein RBBP7 is a protein that is encoded by the RBBP7 gene.This protein is a ubiquitously expressed nuclear protein and belongs to a highly conserved subfamily of WD-repeat proteins. It is found among several proteins that binds directly to retinoblastoma protein, which regulates cell proliferation. The encoded protein is found in many histone deacetylase complexes, including mSin3 co-repressor complex. It is also present in protein complexes involved in chromatin assembly. This protein can interact with BRCA1 tumor-suppressor gene and may have a role in the regulation of cell proliferation and differentiation.
 

| 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)	10	5	2.5	1.25	0.625	0.312	0.156	0
OD	2.1	1.86	1.36	0.94	0.57	0.36	0.25	0.09
Corrected OD	2.01	1.77	1.27	0.85	0.48	0.27	0.16	-

 

| Repeatability

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

| Recovery

The recovery of Human RBBP7 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	95
Plasma(n=8)	92-105	103
Cell Lysates(n=8)	96-108	105

 

| Linearity

Samples were spiked with high concentrations of Human RBBP7 and diluted with Universal Diluent to produce samples with values within the range of the assay.

 

		Serum(n=4)	Plasma(n=4)	Cell Lysates(n=4)
1 : 2	Range (%)	84-95	88-95	90-110
	Average (%)	91	93	96
1 : 4	Range (%)	89-103	87-108	105-113
	Average (%)	94	98	107
