| RALBP1

RalA-binding protein 1 is a protein that is encoded by the RALBP1 gene.RALBP1 plays a role in receptor-mediated endocytosis and is a downstream effector of the small GTP-binding protein RAL. Small G proteins, such as RAL, have GDP-bound inactive and GTP-bound active forms, which shift from the inactive to the active state through the action of RALGDS, which in turn is activated by RAS.
 

| 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	2.32	1.7	1.19	0.72	0.46	0.32	0.22	0.07
Corrected OD	2.25	1.63	1.12	0.65	0.39	0.25	0.15	-

 

| Repeatability

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

| Recovery

The recovery of Human RALBP1 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)	82-101	96
Cell Lysates(n=8)	92-105	101

 

| Linearity

Samples were spiked with high concentrations of Human RALBP1 and diluted with Universal Diluent to produce samples with values within the range of the assay.

 

		Tissue Homogenates(n=4)	Cell Lysates(n=4)
1 : 2	Range (%)	85-95	88-96
	Average (%)	91	93
1 : 4	Range (%)	89-102	87-108
	Average (%)	94	102
