Title: Expression and purification of recombinant soluble tissue factor
Inventor: REZAIE ALIREZA
IPC: G01N33/68
Filed: 1992-12-29
Granted: 1999-05-11
Abstract: A method is disclosed to make any protein in a form that can be isolated rapidly from a solution using a specific monoclonal antibody designated "HPC-4". It has now been determined that it is possible to form a fusion protein of the epitope with a protein to be isolated, and isolate the protein using HPC-4-based affinity chromatography. In the preferred embodiment, a specific protease cleavage site is inserted between the epitope and the protein so that the epitope can be easily removed from the isolated protein. In an example, a functionally active soluble tissue factor including the twelve amino acid epitope recognized in. combination with calcium by HPC-4 and a factor Xa cleavage site was expressed from a vector inserted into a procaryotic expression system. The recombinant tissue factor can be rapidly isolated in a single chromatographic step using the HPC-4 monoclonal antibody immobilized on a suitable substrate. Once isolated, the Protein C epitope is removed by cleavage with factor Xa, leaving the functionally active, soluble tissue factor.

Abstract: Chemical (typically kraft) pulp having enhanced intrinsic fiber strength and bleachability compared to pulp produced using conventional or modified kraft cooking is produced by using high alkali and/or pH cooking, preferably by adding the vast majority of cooking liquor (such as kraft white liquor) after the first removal of liquid from the digester so that the effective alkali concentration is high near the end of the cook. That is during at least the last minute (preferably at least the last 15 minutes and most preferably at least the last 30 minutes) before the cook is terminated the effective alkali concentration is between 15-g/l, more preferably between about 18-40 g/l, and most preferably between about 20-35 g/l. More than 50% (in fact most preferably more than 90%) of the total alkali added to the slurry in order to produce the chemical pulp is added after the first removal of liquid from the digester, and the alkali is added at two or more different locations so that the highest effective alkali concentration is within the range set forth above. The extracted liquors having a high effective alkali concentration are reused in the earlier stages of the cooking to avoid an increase in the addition and consumption of fresh alkali. Also a hydraulic or vapor phase continuous digester is provided with a quench circulation and alkali and heat are added to the quench circulation to control the final kappa number of the pulp, and so that the effective alkali concentration just before termination of the cooking zone is within the above ranges.
