| JTB

The jumping translocation breakpoint protein (JTB), also known as prostate androgen-regulated protein (PAR), is a protein that is encoded by the JTB gene. It is an orphan receptor with unknown function.The JTB family of proteins contains several jumping translocation breakpoint proteins or JTBs. Jumping translocation (JT) is an unbalanced translocation that comprises amplified chromosomal segments jumping to various telomeres. JTB has been found to fuse with the telomeric repeats of acceptor telomeres in a case of JT. Homo sapiens JTB (hJTB) encodes a transmembrane protein that is highly conserved among divergent eukaryotic species.
 

| 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	2.22	1.43	0.87	0.52	0.34	0.27	0.22	0.08
Corrected OD	2.14	1.35	0.79	0.44	0.26	0.19	0.14	-

 

| Repeatability

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

| Recovery

The recovery of Human JTB 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)	92-105	103
Cell Culture Supernates(n=8)	95-108	105

 

| Linearity

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

 

		Tissue Homogenates(n=4)	Cell Culture Supernates(n=4)
1 : 2	Range (%)	88-96	90-110
	Average (%)	92	96
1 : 4	Range (%)	87-106	105-115
	Average (%)	98	108
