Growth Factors and Cytokines

Growth factors are part of cell signaling pathways that are essential for development and cell differentiation. Gold Biotechnology is excited to offer an ever-increasing number of recombinant proteins including cytokines, fibroblast growth factors (FGFs), interleukins and neurotrophic factors. Originated from human, murine, rat and other assorted species, our high-quality recombinant proteins have a purity level exceeding 95% in most cases and also have excellent bioactivity with low endotoxin levels. GoldBio recombinant proteins are typically derived from an E. coli source and are fully biologically active in mammalian cell culture. Our growth factors provide your research with comparable activity but at just a fraction of the price of other commercially available recombinant proteins so that your research funds can be better focused on what really matters.

Our vast collection of trusted growth factors, cytokines and peptide hormones is designed to allow you to perform a myriad of cell signaling mechanism experiments with reproducible results. You can use our cytokines, including chemokines, colony stimulating factors (CSFs) and stem cell factors (KITLG), as well as individually separate cytokine families, such as fibroblast growth factors (FGFs) and interleukins to study cell proliferation, chemotaxis and inflammation, cell migration differentiation and migration and immune system regulation in your cell culture or animal model.

We also offer many different platelet derived growth factors (PDGFs) and VEGFs that will allow you to study angiogenesis, vascularization, and cell proliferation and migration and many other cellular processes. Our EGFs will serve as effective signaling molecules for your cell proliferation, differentiation, immune system and cancer research. We also carry high-quality amyloids and neurotrophic factors for the study of Alzheimer's and Parkinson's disease and other neurodegenerative disorders as well as neuron development and maintenance. Neurotrophic factors regulate neuron growth and maintenace and are an essential tool in the study of the nervous system.

Sonic hedgehog (SHH), bone morphogenetic protein and Noggin are signal transducers and essential for embryonic development—neurulation, cell differentiation other developmental processes—and their deregulation may result in development of cancer. GoldBio offers SHH, BNPs and Noggins that will help you investigate different signaling mechanisms while giving reproducible and trusted results.


Find relevant articles, charts and protocols to choose and use the appropriate growth factors and cytokines in your experiment. You can also find in our videos demonstrations of cell culture methods and techniques that will help you plan growth factor treatments for your experimental setup. Here you can also access our Growth Factor Handbook, which contains a description of popular growth factors' activity, functions and role in different organisms.
