pINFUSE-hIgG4-Fc

INFUSE-hIgG4-Fc1 is a cloning plasmid for the generation of a Fc-fusion protein expressing the Fc region (CH2 and CH3 domains) of the human IgG4 heavy chain and the hinge region. The hinge serves as a flexible spacer between the two parts of the Fc-fusion protein, allowing each part of the molecule to function independently. A short intron is present between each region (one intron between the hinge and CH2 and one intron between CH2 and CH3). The presence of introns is known to enhance the level of gene expression as splicing is known to promote rapid and efficient mRNA export.

pINFUSE-hIgG4-Fc2 additionally features the IL2 signal sequence for the generation of Fc-Fusion proteins derived from proteins that are not naturally secreted
