| FGFR4

Fibroblast growth factor receptor 4 (FGFR-4) is a protein that in humans is encoded by the FGFR4 gene. FGFR4 has also been designated as CD334 (cluster of differentiation 334).The protein encoded by this gene is a member of the fibroblast growth factor receptor family, where amino acid sequence is highly conserved between members and throughout evolution. FGFR family members differ from one another in their ligand affinities and tissue distribution.
 

| 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	0.62	0.31	0.15	0
OD	1.99	1.21	0.64	0.35	0.26	0.21	0.18	0.08
Corrected OD	1.91	1.13	0.56	0.27	0.18	0.13	0.1	-

 

| Repeatability

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

| Recovery

The recovery of Human FGFR4 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)	83-101	96
Cell Lysates(n=8)	93-105	102
Cell Culture Supernates(n=8)	96-108	104

 

| Linearity

Samples were spiked with high concentrations of Human FGFR4 and diluted with Universal Diluent to produce samples with values within the range of the assay.
