Select The Best Cytokine For Optimal Cell Growth

Cytokine Overview
Cytokines are a class of small molecule proteins with extensive biological activity that are synthesized and secreted by immune cells after stimulation. They exert their biological effects by binding to corresponding receptors on the surface of target cells. According to their functions, they are mainly divided into the following 7 categories, as shown in Table 1. At present, recombinant cytokines are widely used in research fields such as cell culture and differentiation, preparation of high-standard cell culture media, research and development and production of new drugs, and cell therapy, so they have very broad application prospects.

Applications
1. Cell culture experiments, cell therapy, cell apoptosis research, stem cell culture and expansion differentiation (IPS), functional analysis;2. As an antigen, used to produce high-quality antibodies;3. Used as a standard in ELISA and other analytical methods.

Features
1.  High biological activity : lower ED50, higher protein specific activity.
2.  Low endotoxin : tested by LAL method, most of them are < 0.1EU/μg, and some are < 0.01EU/μg.
3.  Tag-free : Has sequence information consistent with the natural protein.
4.  High purity : >95%, double detected by SDS-PAGE and HPLC.
5.  Product form : Freeze-dried powder . Compared with liquid, freeze-dried powder products have better stability and are easier to store for a long time.
6. Carrier Free: Stored in PBS, without BSA.
7.  Available from stock , various specifications are available.
