Print Disputes between the United States and China regarding transfer of technology and intellectual property are of long-standing nature. The more economically significant elements of China's practices addressed by US complaints are not well-addressed by WTO rules. US criticism of China's industrial policy may reflect a fundamental difference in national governance models.

INQUIRY The transfer or "blotting" of electrophoretic separated proteins from the gel matrix to a membrane typically nitrocellulose or PVDF followed by subsequent antibody-based detection on the surface of the membrane is called Western Blot or Immunoblot.

Creative Proteomics provides western blotting analysis for the detection of a specific target protein out of a complex protein mixture, e. The resulting data allow both qualitative and semi-quantitative analysis of the protein of interest.

The Western Blot is a widely used analytical technique for the detection of specific proteins in a sample of tissue homogenate or extract. It uses gel electrophoresis to separate native proteins by 3-D structure, or denatured proteins by the length of the polypeptide. The separated proteins are then transferred to a membrane typically nitrocellulose or PVDFwhere they are stained with antibodies specific to the target protein.

Western Blot is widely used in the fields of molecular biology, biochemistry, immune genetics and other molecular biology disciplines. Blotting is the transfer of macromolecules on immobilizing membranes for specific and sensitive detection. In Western Blot analysis, the proteins of the sample are first separated in gel electrophoresis by isoelectric point pImolecular weight, electric charge, or a combination of these factors using various methods such as SDS-PAGE and IEF.

Usually SDS-PAGE is employed for the separation, because all the proteins are solubilized and migrate in the same direction, and the epitopes are easier accessible due to the denaturing effect of SDS. After the gel electrophoresis analysis, the proteins are moved from within the gel onto a membrane made of nitrocellulose or polyvinylidenedifluoride PVDF to make them accessible for antibody detection.

PVDF membranes have a higher binding capacity for proteins than nitrocellulose, but nitrocellulose binds small proteins better. The primary method for transferring the proteins is called electroblotting which uses an electric current to pull proteins from the gel into the PVDF or nitrocellulose membrane.

There are several ways to perform the electrophoretic transfer: All three have in common is that the gel and the membrane form a sandwich with a stack of filter papers on both sides.

It should be noted that, if isoelectric focusing is used for the separation of the proteins, it is more efficient to transfer the proteins by diffusion with pressure blotting. During electroblotting, the proteins move from within the gel onto the membrane while maintaining the organization they had within the gel.

After the blotting process, which can take about an hour semidry blotting to overnight tank blottingthe proteins are exposed on a thin surface layer for antibody detection.

Besides, the free binding sites of the membrane are blocked with a protein mixture, which will not interfere with the subsequent probing with an antibody. The proteins are first detected by the primary antibody, and then detected with a secondary antibody, which recognizes this particular primary antibody.

The secondary antibody is conjugated with a set of specific molecules, which can be easily detected with a subsequent development procedure with high sensitivity.

The most sensitive detection methods are using enhanced chemiluminescence ECL: This light signal is accumulated by exposing the membrane on an X-ray film, or by placing it into an absolutely dark cabinet where the signal is recorded with a sensitive CCD camera.

With a special variant of ECL, down to 1 pg of a protein band is detectable.The management of technology transfers across multinational organisations. The effective management of intra-company technology transfer can affect all levels of a firm's value chain, including production processes, R&D, and innovation management, as this is often .
