specificity :
This assay has high sensitivity and excellent specificity for detection of human SP-B. No significant cross-reactivity or interference between human SP-B and analogues was observed.
storage stability :
Unopened test kits should be stored at 2 to 8 degree C upon receipt. Please refer to pdf manual for further storage instructions.
other info1 :
Samples: Serum, plasma, urine and cell culture supernates. Assay Type: Sandwich. Detection Range: 0.156 ng/ml -10 ng/ml. Sensitivity: The minimum detectable dose of human SP-B is typically less than 0.039 ng/ml. The sensitivity of this assay, or Lower Limit of Detection (LLD) was defined as the lowest protein concentration that could be differentiated from zero. It was determined the mean O.D value of 20 replicates of the zero standard added by their three standard deviations.
other info2 :
Intra-assay Precision: Intra-assay Precision (Precision within an assay): CV%<8%. Three samples of known concentration were tested twenty times on one plate to assess. Inter-assay: Inter-assay Precision (Precision between assays): CV%<10%. Three samples of known concentration were tested in twenty assays to assess.
products description :
Principle of the assay: This assay employs the quantitative sandwich enzyme immunoassay technique. Antibody specific for SP-B has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and any SP-B present is bound by the immobilized antibody. After removing any unbound substances, a biotin-conjugated antibody specific for SP-B is added to the wells. After washing, avidin conjugated Horseradish Peroxidase (HRP) is added to the wells. Following a wash to remove any unbound avidin-enzyme reagent, a substrate solution is added to the wells and color develops in proportion to the amount of SP-B bound in the initial step. The color development is stopped and the intensity of the color is measured.

ncbi summary :
This gene encodes the pulmonary-associated surfactant protein B (SPB), an amphipathic surfactant protein essential for lung function and homeostasis after birth. Pulmonary surfactant is a surface-active lipoprotein complex composed of 90% lipids and 10% proteins which include plasma proteins and apolipoproteins SPA, SPB, SPC and SPD. The surfactant is secreted by the alveolar cells of the lung and maintains the stability of pulmonary tissue by reducing the surface tension of fluids that coat the lung. The SPB enhances the rate of spreading and increases the stability of surfactant monolayers in vitro. Multiple mutations in this gene have been identified, which cause pulmonary surfactant metabolism dysfunction type 1, also called pulmonary alveolar proteinosis due to surfactant protein B deficiency, and are associated with fatal respiratory distress in the neonatal period. Alternatively spliced transcript variants encoding the same protein have been identified.[provided by RefSeq, Feb 2010]
uniprot summary :
Function: Pulmonary surfactant-associated proteins promote alveolar stability by lowering the surface tension at the air-liquid interface in the peripheral air spaces. SP-B increases the collapse pressure of palmitic acid to nearly 70 millinewtons per meter.
