Buffer

Lyophilized from a 0.2 μm sterile filtered PBS, 6% Trehalose, pH 7.4

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.

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℃.

Description

IL-21 receptor signaling plays a pivotal role in T cell and NK cell differentiation, making the extracellular domain (aa 41–253) a critical tool for dissecting cytokine-mediated immune responses in preclinical primate models. Expressed in mammalian cells to preserve native glycosylation and disulfide architecture, this C-terminally His-tagged protein demonstrates quantified binding to human IL-21 with an EC50 of 15.01–19.43 ng/mL in functional ELISA and a KD of 1.31 nM by surface plasmon resonance, providing validated performance for ligand-receptor interaction studies and competitive inhibition assays. These affinity metrics support its use in therapeutic antibody epitope mapping, blocking antibody screening, and small-molecule inhibitor discovery campaigns targeting IL-21 signaling pathways implicated in cancer immunology. The protein meets the purity and endotoxin criteria typical for quantitative binding assays (>95% pure, <1.0 EU/μg), aligning with standards expected in SPR, biolayer interferometry, and high-throughput screening workflows.
