    摘要: A valve capable of controlling fluid flow at high temperatures and high-pressures. The valve can shut off or regulate flow and combines a small compact shape with the ability to be remotely operated and the ability to process a diverse variety of fluids including polymer melts at extreme temperatures and pressures including two phase fluids. The valve includes a process diaphragm that deflects to seat against a valve seat, a control diaphragm that deflects to contact against a stop surface, and a cylindrical actuating button therebetween. The actuating button has respective end surfaces that contact against the process diaphragm and the control diaphragm. The button end surfaces on the button are spaced apart by a button length. When assembled, the distance between the valve seat and the stop surface is greater than the button length by about the sum of the deflections of the diaphragms.

    摘要: The invention relates to the recombinant expression of a peptide of interest in the form of a fusion protein comprising a solubility tag. The fusion protein comprises at least two portions separated by a cleavable peptide sequence wherein one portion is devoid of cysteine residues and the second portion comprises an effective number of cross-linkable cysteine residues. After cell lysis and isolation of the fusion protein, the fusion protein is subsequently cleaved into a mixture of first and second portions. Oxidative cross-linking is used to selectively precipitate one of the two portions to facilitate simple and effective separation of the peptide of interest.
