    • A compound having a polysaccharide binding domain such as contained by a cellulose and essentially lacking in polysaccharidase activity is purified from other ingredients in a mixture using an affinity partition system. A mixture containing the compound is contacted with a system containing as a first phase an aqueous solution of oligosaccharide polymer such as cellulose and as a second phase a solution of a polymer such as a poly(ethylene glycol)-poly(propylene glycol) copolymer. The compound petitions into the first phase and binds to the oligosaccharide polymer, preferably with a Ka of 103 to 107, to form a complex. The complex is collected, and the compound is dissociated from the oligosaccharide polymer. The compound may be formed of a non-peptide chemical moiety or a peptide moiety linked to a polypeptide having the polysaccharide binding domain. The compound may also be a fusion polypeptide containing the polysaccharide binding domain linked through a protease recognition sequence to a macromolecule such as an enzyme, a hormone or an antibody. The macromolecule can be removed by using a protease to cleave the recognition sequence. Another partition system contains the oligosaccharide polymer and a phase separation inducing agent such as a sulfate or citrate salt that induces separation to produce different phases.
    • 具有多糖结合结构域的化合物,例如由纤维素包含并且基本上不含多糖酶活性的化合物,使用亲和分配系统从混合物中的其它成分中纯化。 将含有化合物的混合物与含有第一相的系统接触,例如纤维素等低聚糖聚合物的水溶液,作为第二相与聚(乙二醇) - 聚(丙二醇)共聚物等聚合物的溶液接触。 化合物进入第一阶段并结合寡糖聚合物,优选用103至107的Ka形成络合物。 收集该络合物,并且该化合物与寡糖聚合物解离。 化合物可以由非肽化学部分或与具有多糖结合结构域的多肽连接的肽部分形成。 化合物还可以是含有通过蛋白酶识别序列连接到大分子如酶,激素或抗体的多糖结合结构域的融合多肽。 可以通过使用蛋白酶切割识别序列来除去大分子。 另一分隔系统含有寡糖聚合物和相分离诱导剂如硫酸盐或柠檬酸盐,其诱导分离以产生不同相。

    • An electrical resistance heating assembly having specially designed electrical insulators is disclosed. The electrical insulators have arms shaped to retain an electrical resistance heating coil which can be quickly, easily, and reliably mounted on the arms of the insulator. Top parts of the arms are generally rectangular or triangular in cross section and the arms are spaced and configured relative to each other to form a generally T-shaped opening between the arms, with the ends of the cross bar of the T-shaped opening forming electrically resistance heating coil retention surfaces. Also, cuts in side surfaces of the insulators may provide additional coil retention surfaces. The insulators have either an extended base portion for directly mounting the insulators to a mounting bar of the electrical resistance heating assembly or the insulators simply comprise slabs of electrically insulating material which are each mounted on a cross bar which is attached to a mounting bar of the electrical resistance heating assembly.
