Application


Coating a plate well (6 well plate) with this recombinant CD14 protein in a T cell specific medium at 1-10 µg / well can be used as 1) a human T cell / receptor interaction studies in vitro or 2) a breast cancer biomarker for diagnosis application when combined with CD16 antigen.Use this procedure as a guideline to determine optimal coating conditions for the culture system of choice.1. Thaw CD14 and dilute to desired concentration using serum-free medium or PBS. The final solution should be sufficiently dilute so the volume added covers the surface evenly (1-10 µg/well, 6 well plate).2. Add appropriate amount of diluted material to culture surface.3. Incubate at room temperature for approximately 1.5 hours.4. Aspirate remaining material.5. Rinse plates carefully with water and avoid scratching bottom surface of plates.6. Plates are ready for use. They may also be stored at 2-8 °C damp or air dried if sterility is maintained.


Preparation Note


The full-length extracellular domain of the human CD14 gene (20-345 aa) was constructed with 29 N-terminal T7/HIS-tag and expressed in E. coli as inclusion bodies. The final product was refolded using our unique “temperature shift inclusion body refolding” technology and chromatographically purified.
