SFTPD produced in Sf9 Baculovirus cells is a single, glycosylated polypeptide chain containing 363 amino acids (22-375 a.a.) and having a molecular mass of 36.5kDa. (Molecular size on SDS-PAGE will appear at approximately 40-57kDa).
SFTPD is expressed with a 9 amino acid His tag at C-Terminus and purified by proprietary chromatographic techniques.
Sf9, Baculovirus cells.
SFTPD protein solution (0.25mg/ml) contains 10% glycerol & Phosphate Buffered Saline (pH 7.4).
For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).
Avoid multiple freeze-thaw cycles.
Greater than 90.0% as determined by SDS-PAGE.
