Pig Pulmonary Surfactant Associated Protein B (SFTPB) ELISA Kit is an ELISA Kit for the in vitro quantitative measurement of Pig Pulmonary Surfactant Associated Protein B / SP-B (SFTPB) concentrations in serum, plasma and other biological fluids.

Introduction 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.
Target Pulmonary Surfactant Associated Protein B (SFTPB)
Reactivity Pig
Tested Applications ELISA
Recommended dilutions Optimal dilutions/concentrations should be determined by the end user.
Storage Shipped at 4 °C. Upon receipt, store the kit according to the storage instruction in the kit's manual.
Validity The validity for this kit is at least 6 months. Up to 12 months validity can be provided on request.
Stability The stability of the kit is determined by the rate of activity loss. The loss rate is less than 5% within the expiration date under appropriate storage conditions. To minimize performance fluctuations, operation procedures and lab conditions should be strictly controlled. It is also strongly suggested that the whole assay is performed by the same user throughout.

Assay Procedure This procedure is provided for reference only. The product manual may differ slightly. The product should be used as stated on the product manual included and delivered together with the product.
  • 1) Set standard, test samples and control wells.
  • 2) Aliquot 100 µl of diluted standard into the standard wells.
  • 3) Aliquot 100 µl of Standard Diluent buffer into control (zero) well.
  • 4) Aliquot 100 µl of diluted samples into the sample wells. Incubate for 1 hr at 37 °C.
  • 5) Aliquot 100 µl of Detection Reagent A to each well. Incubate for 1 hr at 37 °C.
  • 6) Wash 3 times.
  • 7) Aliquot 100 µl of Detection Reagent B to each well. Incubate for 90 mins at 37 °C.
  • 8) Wash 5 times.
  • 9) Aliquot 90 µl of TMB Substrate to each well. Incubate for 10-20 mins at 37 °C.
  • 10) Aliquot 50 µl of Stop Solution.
  • 11) Measure the OD at 450 nm.
Assay Precision Intra-assay Precision (Precision within an assay): 3 samples with low, medium and high levels of Pulmonary Surfactant Associated Protein B / SP-B (SFTPB) were tested 20 times on one plate, respectively.

Inter-assay Precision (Precision between assays): 3 samples with low, medium and high levels of Pulmonary Surfactant Associated Protein B / SP-B (SFTPB) were tested on 3 different plates, 8 replicates in each plate.

CV (%) = (Standard Deviation / mean) × 100

Intra-Assay: CV<10%

Inter-Assay: CV<10%
Availability Shipped within 5-7 working days.
Note This product is for research use only.

The range and sensitivity is subject to change. Please contact us for the latest product information. For accurate results, sample concentrations must be diluted to mid-range of the kit. If you require a specific range, please contact us in advance or write your request in your order comments.

Please note that our ELISA and CLIA kits are optimised for detection of native samples, rather than recombinant proteins. We are unable to guarantee detection of recombinant proteins, as they may have different sequences or tertiary structures to the native protein.
