Description

Application

Coating a plate well (6 well plate) with this recombinant CD2 protein in a T cell specific medium at 1-10 μg/well allows for human T cell differentiation studies in vitro.

Use this procedure as a guideline to determine optimal coating conditions for the culture system of choice.
1. Thaw CD2 and dilute to desired concentration using serum-free medium or PBS. The final solution should be sufficiently dilute so that the volume added covers the surface evenly.
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 CD2 gene (25-209 aa) was constructed with 31 N-terminal T7/HIS-tag and expressed in E. coli as inclusion bodies. The final product was refolded using a unique “temperature shift inclusion body refolding” technology and chromatographically purified.
