Bioassay

We offer top-level service for cell-based assays and immunoassays. We focus on qualification and quantification of biological active molecules, including natural and recombinant cytokines, chemokines, growth factors, and their related antibodies, soluble receptors, receptor agonists/antagonists. All the assays employ non-radioactive commercial available reagents. Assays will be transferred to customers' facilities upon request. We will guarantee the highest quality of the assay results and the fastest turn around time.

Assay categories

• Cell proliferation. Example of molecules: EGF, FGF, SCF, IL-1, IL-2, et al.
• Cytotoxicity. Example of molecules: TNFs, IFNs, et al.
• Chemotaxis (cell migration). Example of molecules: all chemokines, et al.
• Intracellular ion mobilization. Example of molecules: Calcium channel of chemokine receptors, et al.
• Secondary cytokine secretion. Example of molecules: IL-12, IL-17, IL-18, et al.
• Intracellular kinase activation. Example of the molecules: Akt, MAPK, Junk, et al.
• Immunoassay. Ligand-receptor interaction. Quantification of target molecules. et al.

These assays can be used to test the blocking activities of neutralizing antibodies, soluble receptors, and antagonists.

Sample Type

We can test purified molecules as well as crude samples such as conditional media from insect and mammalian cell expression. Samples can be either liquid or lyophilized forms.
