Syd Labs has extensive experience with making DNA constructs for Fc fusion protein production, expressing and purifying a number of Fc fusion proteins from microgram to kilogram scales in mammalian cells, such as CHO and HEK 293 cells. With improved DNA construction system and fully optimized secretion signal and linker sequences, Syd Labs can efficiently complete a project from DNA construction and transient production of Fc fusion proteins in CHO and HEK 293 cells, to Fc fusion protein purification. N-term or C-term of Fc fusions of peptides and proteins in secreted form and multiple Fc backbone are available upon request.
