- 应用备注
- Each Investigator should determine their own optimal working dilution for specific applications.
- 实验流程
-
Protein quantitation was carried out by two independent methods. 1. UV spectroscopy at 280 nm using the absorbency value of 0.54 as the extinction coefficient for a 0.1 % (1 mg/mL) solution.
2. Analysis by RP-HPLC, using a standard solution of IL-21 as a Reference Standard. - 限制

- 背景
-
IL-21 is produced by CD4+ T cells in response to antigenic stimulation. Its action enhances antigen-specific responses of immune cells. The biological effects of IL-21 include induction of differentiation of T-cells-stimulated B-cells into plasma cells and memory B-cells, stimulation (in conjuction) with IL-4 of IgG production, and induction of apoptotic effects in na?ve B-cells and stimulated B-cells in the absence of T-cell signaling. Additionally, IL-21 promotes the anti-tumor activity of CD8+ T-cells and NK cells. IL-21 exerts its effect through binding to a specific type I cytokine receptor, IL-21R, which also contains the gamma chain (°C) found in other cytokine receptors including IL-2, IL-4, IL-7, IL-9 and IL-15. The IL-21/IL-21R interaction triggers a cascade of events which includes activation of the tyrosine kinases JAK1 and JAK3, followed by activation of the transcription factors STAT1 and STAT3.
