    摘要: The present invention relates to a method of preparing a tetrameric protein comprising culturing a host cell transformed or transfected with an expression vector encoding a fusion protein comprising a vasodialator-stimulated phosphoprotein (VASP) domain and a heterologous protein. In one embodiment, the heterologous protein is a membrane protein, the portion of the heterologous protein that included in the fusion protein is the extracellular domain of that protein, and the resulting fusion protein is soluble. The method can be used to produced homo- and hetero-tetrameric proteins. The present invention also encompasses DNA molecules, expression vectors, and host cells used in the present method and fusion proteins produced by the present method.

    摘要: In various embodiments, the present invention provides methods of converting a Fab molecule to a scFv molecule. The methods include amplifying the polynucleotide sequence of the variable light and variable heavy regions of the Fab molecule from the framework 1 to framework 4 sequences; adding one or more restriction endonuclease sites to the amino or carboxyl terminal of the amplified variable region sequence by PCR or ligation; adding one or more linker sequences to the amino or carboxyl terminal of the amplified variable region sequence by PCR or ligation. Additionally, in various embodiments the variable light chain sequence is either amino terminal or carboxyl terminal to the variable heavy chain sequence.
