    • A method of induction of amyloid plaques includes immobilizing a quantity of a selected sulfated glycosaminoglycan (SGAG) on a selected medium and adding to the immobilized SGAG on the medium a quantity of dissolved low fibrillar Anull 1-40 (LFAnull). The LFAnull is added preferably in a Anull:SGAG w/w ratio of about 1:1. SGAGs are preferably selected from heparin, heparan sulfate, keratan sulfate, dermatan sulfate, chondroitin-4-sulfate and chondroitin-6-sulfate. Screening methods and kits for screening either immobilize a quantity of a selected sulfated glycosaminoglycan (SGAG) on a selected medium, followed by adding to a quantity of dissolved low fibrillar Anull 1-40 (LFAnull) a selected quantity of the selected amyloid therapeutic candidate to create a test solution, and then adding to the immobilized SGAG on the medium a selected quantity of the test solution to test for inhibition, or preform amyloid plaques on the medium by immobilizing a quantity of a selected sulfated glycosaminoglycan (SGAG) or a GAG-related macromolecule on a selected medium and then adding a selected quantity of dissolved low fibrillar Anull 1-40 (LFAnull), followed by adding to the amyloid plaques on the medium a selected quantity of a test solution of a selected amyloid therapeutic candidate to test for disruption.
    • 诱导淀粉样蛋白斑块的方法包括将一定数量的选择的硫酸葡糖胺聚糖(SGAG)固定在选定的培养基上,并向培养基上的固定化SGAG加入一定量的溶解的低纤维Aβ1-40(LFAbeta)。 LFAbeta优选以约1:1的Abeta:SGAG w / w比添加。 SGAG优选选自肝素,硫酸乙酰肝素,硫酸角质素,硫酸皮肤素,硫酸软骨素-4-硫酸盐和硫酸软骨素-6-硫酸盐。 用于筛选的筛选方法和试剂盒在选定的培养基上固定一定量的选择的硫酸葡糖胺聚糖(SGAG),然后将一定量的所选择的淀粉样蛋白治疗候选物加入到一定量的溶解的低纤维Aβ1-40(LFAbeta)中 产生一个测试溶液,然后在培养基上加入一定量的测试溶液中的固定化SGAG以测试抑制,或者通过将一定量的选择的硫酸糖胺聚糖(SGAG)或GAG- 然后加入选定量的溶解的低纤维Abeta 1-40(LFAbeta),然后向培养基上的淀粉样蛋白斑添加选定量的所选淀粉样蛋白治疗候选物的测试溶液,以测试 中断

    • Modified human factor VIII cDNA wherein mutations are inserted either in the wild-type factor VIII cDNA or in a factor VIII cDNA in which the B-domain is partially or completely deleted and may be replaced by a DNA linker segment and A) one or several codons of the human factor VIII cDNA which are not identical with the corresponding codon in the same position of the porcine factor VIII cDNA are substituted by a different codon in such a way that when the human sequence contains a codon for a neutral amino acid whereas the porcine sequence contains a codon for a charged amino acid then a codon for an amino acid with the same charge as found in the porcine sequence is introduced into the human sequence; when the human sequence contains a codon for a charged amino acid whereas the porcine sequence contains a codon for a neutral amino acid then a codon for a neutral amino acid or a codon for an amino acid of the opposite charge is introduced into the human sequence, when the human sequence contains a codon for a charged amino acid whereas the porcine sequence contains a codon for an amino acid with the opposite charge then a codon for an amino acid with the opposite charge is introduced into the human sequence or B) one or several codons for a charged amino acid which are found in the FVIII cDNA of a hemophilic patient are replaced by a codon for an amino acid of the opposite charge.
    • 修饰的人因子VIII cDNA,其中突变插入到野生型因子VIII cDNA或其中B结构域部分或完全缺失的因子VIII cDNA中,并且可以被DNA接头片段代替,并且A)一个或多个 与人因子VIII cDNA相同位置的相应密码子不同的人因子VIII cDNA的密码子被不同的密码子取代,使得当人序列含有中性氨基酸的密码子时 猪序列含有带电荷的氨基酸的密码子,然后将与猪序列中发现的相同电荷的氨基酸的密码子引入人序列; 当人序列含有带电荷氨基酸的密码子,而猪序列含有中性氨基酸的密码子时,则将中性氨基酸的密码子或相反电荷的氨基酸的密码子引入人序列中, 当人类序列含有带电荷氨基酸的密码子,而猪序列含有具有相反电荷的氨基酸的密码子时,具有相反电荷的氨基酸的密码子被引入人序列或B)一个或多个 在血友病患者的FVIII cDNA中发现的带电荷的氨基酸的密码子被相反电荷的氨基酸的密码子替代。
