| SP-B

Surfactant protein B is an essential lipid-associated protein found in pulmonary surfactant. Without it, the lung would not be able to inflate after a deep breath out. It rearranges lipid molecules in the fluid lining the lung so that tiny air sacs in the lung, called alveoli, can more easily inflate. SP-B plays a critical role in the functioning of healthy lungs, and its absence inevitably leads to lung conditions, most common of which being acute respiratory distress syndrome (ARDS). Because of this, SP-B's function has been well researched, and has been found to exist in three parts. Beyond these three functions, it is worth noting that SP-B is also thought to have some anti-inflammatory function, though it is not well defined.

| 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)	50	25	12.5	6.25	3.12	1.56	0.78	0
OD	2.08	1.31	0.75	0.5	0.33	0.25	0.21	0.09
Corrected OD	1.99	1.22	0.66	0.41	0.24	0.16	0.12	-

| Repeatability

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

| Recovery

The recovery of Mouse SP-B 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)	84-102	96
Cell Lysates(n=8)	92-105	102
Cell Culture Supernates(n=8)	96-108	105

| Linearity

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