IL-33 Protein, Cynomolgus (Biotinylated, HEK293, His-Avi)

The IL-33 protein is part of the IL-1 family, a different cytokine that is critical in immune responses and inflammation. IL-33 acts through its receptor ST2 to promote the activation and recruitment of immune cells such as Th2 cells, mast cells, and eosinophils to sites of inflammation. IL-33 Protein, Cynomolgus (Biotinylated, HEK293, His-Avi) is the recombinant cynomolgus-derived IL-33 protein, expressed by HEK293, with C-Avi;C-His labeled tag.

Description

The IL-33 protein is part of the IL-1 family, a different cytokine that is critical in immune responses and inflammation. IL-33 acts through its receptor ST2 to promote the activation and recruitment of immune cells such as Th2 cells, mast cells, and eosinophils to sites of inflammation. IL-33 Protein, Cynomolgus (Biotinylated, HEK293, His-Avi) is the recombinant cynomolgus-derived IL-33 protein, expressed by HEK293, with C-Avi;C-His labeled tag.

Background

IL-33 protein belongs to the IL-1 family and is known for its high divergence from other family members. It functions as an important cytokine involved in various immune responses and inflammatory processes. IL-33 plays a crucial role in promoting the activation and recruitment of immune cells, such as T-helper 2 (Th2) cells, mast cells, and eosinophils, to sites of inflammation. It is primarily produced by epithelial and endothelial cells and acts through its receptor, ST2, to induce the production of other pro-inflammatory cytokines and chemokines. IL-33 has been implicated in various diseases, including asthma, allergic diseases, and autoimmune disorders, highlighting its significance as a therapeutic target for modulating immune responses.

Reconstitution

It is not recommended to reconstitute to a concentration less than 100 μg/mL in ddH2O. For long term storage it is recommended to add a carrier protein (0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose).

Storage & Stability

Stored at -20°C for 2 years from date of receipt. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer (with carrier protein). It is recommended to freeze aliquots at -20°C or -80°C for extended storage.

Shipping

Room temperature in continental US; may vary elsewhere.
