| SP-D

Surfactant Associated Protein D (SPD) is a pattern-recognition molecule that is an important component of the mucosal immune system of the reproductive tract (FRT). In addition to its host defense function in the FRT, it has an immunomodulatory role in labor and preterm delivery. Its deficiency affects the fertility of female organisms, highlighting the role of SPD in ovarian and uterine physiology.

| 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 (pg/mL)	500	250	125	62.5	31.2	15.6	7.8	0
OD	2.44	1.87	1.29	0.83	0.58	0.38	0.27	0.08
Corrected OD	2.36	1.79	1.21	0.75	0.5	0.3	0.19	-

| Repeatability

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

| Recovery

The recovery of Rat SP-D 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)	92-104	101

| Linearity

Samples were spiked with high concentrations of Rat SP-D and diluted with Universal Diluent to produce samples with values within the range of the assay.

		Serum(n=4)	Plasma(n=4)
1 : 2	Range (%)	84-95	88-96
1 : 2	Average (%)	91	92
1 : 4	Range (%)	89-103	87-108
1 : 4	Average (%)	94	98
