Description of Human CD14, soluble (glycosylated)

The CD14 is produced from human CD14 transfected CHO-cells. Before transfection the complete human CD14-cDNA was amplified by PCR and cloned into expression vector p-POL-DHFR. The myeloid differentiation antigen CD14 acts as the major receptor for bacterial LPS. The dominant form of the recombinant wild type CD14 is the 50-kDa protein containing 335 amino acids and lacks the GPI-Anchor.

Biological Activity

Up to 20 µg/ml CD14 inhibit binding of FITC-LPS (0.5µg/ml) to 600,000 CD14+CHO transfectants (FACS).

Reconstitution

It is recommended to reconstitute the lyophilized CD14 in sterile 18MO-cm H₂O not less than 100µg/ml. Further dilutions should be made with phosphate buffered saline (PBS).

Stability

Lyophilized CD14 although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution CD14 should be stored at 4°C between 2-7 days and for future use below -18°C.For long term storage it is recommended to add a carrier protein (0.1% HSA, order number: 2835.955.xyz or 2835.958.xyz, or BSA, order number: 2835.919.xyz). Please avoid repeated freeze-thaw cycles.
