Research Topic: Cell Biology

Uniprot ID: P07988

Gene Names: SFTPB

Organism: Homo sapiens (Human)

AA Sequence: FPIPLPYCWLCRALIKRIQAMIPKGALAVAVAQVCRVVPLVAGGICQCLAERYSVILLDTLLGRMLPQLVCRLVLRCSM

Expression Region: 201-279aa

Sequence Info: Full Length of Mature Protein

Source: Yeast

Tag Info: NO-tagged

MW: 8.7 kDa

Alternative Name(s): 18KDA pulmonary-surfactant protein 6KDA protein Pulmonary surfactant-associated proteolipid SPL(Phe)

Relevance: 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.

Purity: Greater than 90% as determined by SDS-PAGE.

Storage Buffer: Tris-based buffer,50% glycerol

Storage: The shelf life is related to many factors, storage state, buffer ingredients, storage temperature and the stability of the protein itself. Generally, the shelf life of liquid form is 6 months at -20℃/-80℃. The shelf life of lyophilized form is 12 months at -20℃/-80℃.

Notes: Repeated freezing and thawing is not recommended. Store working aliquots at 4℃ for up to one week.
