Product Overview

Abbreviation
Recombinant Human SFTPB protein
Alternative names
18KDA pulmonary-surfactant protein 6KDA protein Pulmonary surfactant-associated proteolipid SPL(Phe)
Buffer [rich text]
If the delivery form is liquid, the default storage buffer is Tris/PBS-based buffer, 5%-50% glycerol. If the delivery form is lyophilized powder, the buffer before lyophilization is Tris/PBS-based buffer, 6% Trehalose, pH 8.0.
Endotoxin
Not test
Expression region
201-279aa
Form
Liquid or Lyophilized powder
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.
Gene names
SFTPB
Mw
8.7 kDa
Notes
Repeated freezing and thawing is not recommended. Store working aliquots at 4℃ for up to one week.
Organism
Homo sapiens (Human)
Protein length
Full Length of Mature Protein
Purity
Greater than 90% as determined by SDS-PAGE.
Reconstitution [rich text]
We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Please reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg/mL.We recommend to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20℃/-80℃. Our default final concentration of glycerol is 50%. Customers could use it as reference.

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℃.
