Description

Recombinant human CD19 protein is produced by our Mammalian expression system and the target gene encoding Pro20-Lys291 is expressed with a Fc tag at the C-terminus.

Research Area

Epigenetics, Immunology

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.
