Description

Mouse Sftpb (Pulmonary surfactant-associated protein B) ELISA Kit

The Mouse SFTPB (Pulmonary Surfactant-Associated Protein B) ELISA Kit is a powerful tool for researchers studying respiratory diseases and conditions affecting the lungs. This kit is specifically designed for the accurate detection of SFTPB levels in mouse serum, plasma, and cell culture supernatants.Pulmonary surfactant-associated protein B is a critical component of pulmonary surfactant, which plays a vital role in maintaining lung function and preventing collapse of the alveoli. Dysregulation of SFTPB levels has been associated with a variety of respiratory diseases, including acute respiratory distress syndrome (ARDS) and certain types of interstitial lung diseases.

With its high sensitivity and specificity, this ELISA kit provides researchers with reliable and reproducible results, making it an essential tool for studying the role of SFTPB in lung health and disease. By accurately quantifying SFTPB levels, researchers can better understand the pathophysiology of respiratory conditions and develop potential therapies to improve patient outcomes.

serum(n=5)0-3924
EDTA plasma(n=5)25-9469
heparin plasma(n=5)15-6138
Linearity: The linearity of the kit was assayed by testing samples spiked with appropriate concentration of Sftpb and their serial dilutions. The results were demonstrated by the percentage of calculated concentration to the expected.

When carrying out an ELISA assay it is important to prepare your samples in order to achieve the best possible results. Below we have a list of procedures for the preparation of samples for different sample types.

Sample TypeProtocol
Serum If using serum separator tubes, allow samples to clot for 30 minutes at room temperature. Centrifuge for 10 minutes at 1,000x g. Collect the serum fraction and assay promptly or aliquot and store the samples at -80°C. Avoid multiple freeze-thaw cycles.

If serum separator tubes are not being used, allow samples to clot overnight at 2-8°C. Centrifuge for 10 minutes at 1,000x g. Remove serum and assay promptly or aliquot and store the samples at -80°C. Avoid multiple freeze-thaw cycles.

PlasmaCollect plasma using EDTA or heparin as an anticoagulant. Centrifuge samples at 4°C for 15 mins at 1000 × g within 30 mins of collection. Collect the plasma fraction and assay promptly or aliquot and store the samples at -80°C. Avoid multiple freeze-thaw cycles. Note: Over haemolysed samples are not suitable for use with this kit.
Urine & Cerebrospinal FluidCollect the urine (mid-stream) in a sterile container, centrifuge for 20 mins at 2000-3000 rpm. Remove supernatant and assay immediately. If any precipitation is detected, repeat the centrifugation step. A similar protocol can be used for cerebrospinal fluid.
Cell culture supernatantCollect the cell culture media by pipette, followed by centrifugation at 4°C for 20 mins at 1500 rpm. Collect the clear supernatant and assay immediately.
Cell lysatesSolubilize cells in lysis buffer and allow to sit on ice for 30 minutes. Centrifuge tubes at 14,000 x g for 5 minutes to remove insoluble material. Aliquot the supernatant into a new tube and discard the remaining whole cell extract. Quantify total protein concentration using a total protein assay. Assay immediately or aliquot and store at ≤ -20 °C.
Tissue homogenatesThe preparation of tissue homogenates will vary depending upon tissue type. Rinse tissue with 1X PBS to remove excess blood & homogenize in 20ml of 1X PBS (including protease inhibitors) and store overnight at ≤ -20°C. Two freeze-thaw cycles are required to break the cell membranes. To further disrupt the cell membranes you can sonicate the samples. Centrifuge homogenates for 5 mins at 5000xg. Remove the supernatant and assay immediately or aliquot and store at -20°C or -80°C.
Tissue lysatesRinse tissue with PBS, cut into 1-2 mm pieces, and homogenize with a tissue homogenizer in PBS. Add an equal volume of RIPA buffer containing protease inhibitors and lyse tissues at room temperature for 30 minutes with gentle agitation. Centrifuge to remove debris. Quantify total protein concentration using a total protein assay. Assay immediately or aliquot and store at ≤ -20 °C.
Breast MilkCollect milk samples and centrifuge at 10,000 x g for 60 min at 4°C. Aliquot the supernatant and assay. For long term use, store samples at -80°C. Minimize freeze/thaw cycles.
