| GATA3

GATA3 is a transcription factor that is encoded by the GATA3 gene. Studies in animal models and humans indicate that it controls the expression of a wide range of biologically and clinically important genes. The GATA3 transcription factor is critical for the embryonic development of various tissues as well as for inflammatory and humoral immune responses and the proper functioning of the endothelium of blood vessels. GATA3 plays central role in allergy and immunity against worm infections.GATA3 haploinsufficiency (i.e. loss of one or the two inherited GATA3 genes) results in a congenital disorder termed the Barakat syndrome.
 

| 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)	2000	1000	500	250	125	62.5	31.2	0
OD	2.26	1.46	0.85	0.57	0.37	0.28	0.22	0.07
Corrected OD	2.19	1.39	0.78	0.5	0.3	0.21	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 GATA3 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)	93-105	102

 

| Linearity

Samples were spiked with high concentrations of Human GATA3 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 (%)	84-95	88-96
	Average (%)	92	93
1 : 4	Range (%)	89-103	87-108
	Average (%)	94	98
