Recombinant Human CD70 protein, His & GST-tagged

Specification :
| Description : The protein encoded by this gene is a cytokine that belongs to the tumor necrosis factor (TNF) ligand family. This cytokine is a ligand for TNFRSF27/CD27. It is a surface antigen on activated, but not on resting, T and B lymphocytes. It induces proliferation of costimulated T cells, enhances the generation of cytolytic T cells, and contributes to T cell activation. This cytokine is also reported to play a role in regulating B-cell activation, cytotoxic function of natural killer cells, and immunoglobulin sythesis. | Source : E. coli | Species : Human | Tag : His & GST | Form : Freeze-dried powder | Molecular Mass : 43kDa as determined by SDS-PAGE reducing conditions. | Protein length : Gln47~Val191 (Accession # P32970) | Endotoxin : | Purity : >95% | Characteristic : The isoelectric point is 6.8. | 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 liquid form in Phosphate buffered saline(PBS), pH 7.4. | Reconstitution : Reconstitute in sterile PBS, pH7.2-pH7.4.
