| RSPO1

R-spondin-1 is a secreted protein that is encoded by the RSPO1 gene, found on chromosome 1. It interacts with WNT4 in the process of female sex development. Loss of function can cause female to male sex reversal. Furthermore, it promotes canonical WNT/β catenin signaling.The protein has two cysteine-rich, furin-like domains and one thrombospondin type 1 domain.
 

| 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	1.5	0.87	0.52	0.35	0.24	0.18	0.08
Corrected OD	2.24	1.42	0.79	0.44	0.27	0.16	0.1	-

 

| Repeatability

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

| Recovery

The recovery of Mouse RSPO1 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
Cell Lysates(n=8)	90-105	102
Cell Culture Supernates(n=8)	96-108	106

 

| Linearity

Samples were spiked with high concentrations of Mouse RSPO1 and diluted with Universal Diluent to produce samples with values within the range of the assay.
