Recombinant Zebrafish il4 protein

• Cat.No.: il4-22Z
• Product Overview: Recombinant Zebrafish il4 was expressed in Yeast.

Specification

• Species: Zebrafish
• Source: Yeast
• Tag: Non
• Description: Interleukin-4 (IL-4) induces differentiation of naive helper T cells (Th0 cells) to Th2 cells. Upon activation by IL-4, Th2 cells subsequently produce additional IL-4. IL-4 has many biological roles, including the stimulation of activated B-cell and T-cell proliferation, and the differentiation of CD4+ T-cells into Th2 cells. It is a key regulator in humoral and adaptive immunity. IL-4 induces B-cell class switching to IgE, and up-regulates MHC class II production. Overproduction of IL-4 is associated with allergies.
• Form: Lyophilized without carrier protein.
