Description

IL-3, also known as Interleukin-3, is a cytokine that is produced by activated T cells and mast cells. It plays a crucial role in regulating the growth, differentiation, and function of various cell types in the immune system. human IL-3 is an important cytokine that regulates the growth, differentiation, and function of immune cells. Its study contributes to our understanding of immune system regulation and its potential applications in immunotherapy and disease treatment.

Reconstitution

We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Reconstitute in sterile distilled water or aqueous buffer containing 0.1% BSA to a concentration of 0.1-1.0 mg/mL. Stock solutions should be apportioned into working aliquots and stored at ≤ -20°C. Further dilutions should be made in appropriate buffered solutions.
