Recombinant Rat Sftpb protein, His & T7-tagged

• Cat.No.: Sftpb-1721R
• Product Overview: Recombinant Rat Sftpb aa. (Arg111~His329 (Accession # XM_006236657.2)) fused with N-terminal His & T7 tag was produced in E. coli cells.

Specification

• Description: Acts to lower surface tension in lung alveoli.
• Source: E. coli
• Species: Rat
• Tag: His&T7
• Form: Freeze-dried powder
• Molecular Mass: Predicted Molecular Mass: 28.4kDa
• Protein length: Arg111~His329
• Endotoxin: <1.0EU per 1ug (determined by the LAL method)
• Purity: >95%
• Characteristic: The isoelectric point is 8.3.
• Applications: SDS-PAGE; WB; ELISA; IP.
• Stability: The thermal stability is described by the loss rate of the target protein. The loss rate was determined by accelerated thermal degradation test, that is, incubate the protein at 37°C for 48h, and no obvious degradation and precipitation were observed. (Referring from China Biological Products Standard, which was calculated by the Arrhenius equation.) The loss of this protein is less than 5% within the expiration date under appropriate storage condition.
• Storage: Avoid repeated freeze/thaw cycles. Store at 2-8°C for one month. Aliquot and store at -80°C for 12 months.
• Storage buffer: Supplied as lyophilized form in PBS, pH7.4, containing 5% trehalose, 0.01% sarcosyl.
• Reconstitution: Reconstitute in sterile PBS, pH7.2-pH7.4.
