| FcεRIα

Fc fragment of IgE, high affinity I, receptor for; alpha polypeptide, also known as FCER1A, is a protein which is encoded by the FCER1A gene.The high affinity IgE receptor plays a central role in allergic disease, coupling allergen and mast cell to initiate the inflammatory and immediate hypersensitivity responses that are characteristic of disorders such as hay fever and asthma. The allergic response occurs when 2 or more IgE receptors are crosslinked via IgE molecules that in turn are bound to an allergen (antigen) molecule. A perturbation occurs that brings about the release of histamine and proteases from the granules in the cytoplasm of the mast cell and leads to the synthesis of prostaglandins and leukotrienes—potent effectors of the hypersensitivity response.

| 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	2.51	1.96	1.24	0.72	0.46	0.3	0.22	0.09
Corrected OD	2.42	1.87	1.15	0.63	0.37	0.21	0.13	-

| Repeatability

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

| Recovery

The recovery of Human FcεRIα spiked at three different levels in samples throughout the range of the assay was evaluated in various matrices.

Sample Type	Range(%)	Average Recovery(%)
Serum(n=8)	84-101	96
Plasma(n=8)	92-106	103
Cell Culture Supernates(n=8)	96-108	105

| Linearity

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

		Serum(n=4)	Plasma(n=4)	Cell Culture Supernates(n=4)
1 : 2	Range (%)	84-95	88-95	90-110
1 : 2	Average (%)	91	92	96
1 : 4	Range (%)	89-103	87-108	105-115
1 : 4	Average (%)	94	98	108
