Technical Data
Prosurfactant Protein B, CT (proSP-B)
Pulmonary surfactant is a lipid-rich material that prevents lung collapse by lowering surface tension at the air-liquid interface in the alveoli of lung. It is composed primarily of phospholipids (phosphatidylcholine and phosphatidylglycerol) and lesser amounts of cholesterol and surfactant-associated protein. Prosurfactant Protein B is a precursor of a very hydrophobic protein of the surfactant.

Suitable for use in Immunohistochemistry, Western Blot and ELISA. Other applications have not been tested.

Recommended Dilutions:
Immunohistochemistry: 1:2000-1:4000 on human tissue with and without antigen retrieval and 1:1000-1:2000 on adult mouse lung or 1:500 on fetal mouse lung.
Western Blot: 1:1000-1:5000
ELISA: 1:500-1:1000
Optimal dilutions to be determined by the researcher.

Storage and Stability:
May be stored at 4C for short-term only. Aliquot to avoid repeated freezing and thawing. Store at -20C. Aliquots are stable for 12 months. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap.
