Growth factors and cytokines are involved in cell-to-cell signaling and are essential to many cellular and organismal processes. While growth factors are commonly associated with processes such as development and healing, cytokines are a broader class of proteins associated with numerous aspects of immune function. Both growth factors and cytokines are implicated in tumor formation. QED Bioscience offers an extensive selection of antibodies for growth factors, cytokines and their receptors, including common targets such as IGF-1, insulin receptor, fibroblast growth factor receptor, IL-1 and TNF-R1. Many of our antibodies have been validated for multiple immunoassay applications and provide well-characterized results for your research program.
