Human CD28 protein

SKU: orb391397

Description

Recombinant human CD28 protein is produced by our mammalian expression system and the target gene encoding Asn19-Pro152 is expressed with a Fc tag at the C-terminus.

Research Area

Immunology & Inflammation

Images & Validation

• Tested Applications: ELISA, MS, SDS-PAGE, WB
• Application Notes:
  Always centrifuge tubes before opening. Do not mix by vortex or pipetting. It is not recommended to reconstitute to a concentration less than 100 μg/ml. Dissolve the lyophilized protein in 1X PBS. Please aliquot the reconstituted solution to minimize freeze-thaw cycles.
