(CD27 ligand)(CD27-L)(Tumor necrosis factor ligand superfamily member 7)(CD antigen CD70)
Reconstitution
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°C/-80°C. Our default final concentration of glycerol is 50%. Customers could use it as reference.
Tag
N-terminal hFc-tagged
Molecular Weight
67.8 kDa
Relevance
Cytokine which is the ligand for CD27. The CD70-CD27 pathway plays an important role in the generation and maintenance of T cell immunity, in particular during antiviral responses. Upon CD27 binding, induces the proliferation of costimulated T-cells and enhances the generation of cytolytic T-cells.
Source
Mammalian cell
Endotoxin Level
Not test.
Form
Liquid or Lyophilized powder
Notes
Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.
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.
Purity
Greater than 90% as determined by SDS-PAGE.
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°C/-80°C. The shelf life of lyophilized form is 12 months at -20°C/-80°C.
